Traditional fire-fighting methods for fighting fires in storage vessels containing flammable liquids may require the application of a plurality of fire-fighting agents issued from one or more discharging apparatuses. These methods include: a) Long range fire-fighting methods including fixed, semi-portable or portable systems that discharge fire-fighting agents from a position located afar from the storage vessel. These include fixed monitors, semi-portable monitors, fixed cannons, vehicle mounted cannons, hand held nozzles, etc. b) Fixed systems permanently installed on the storage vessel. These include fixed foam chambers mounted on the roof of the storage vessel, circumferential discharge system or seal area protection systems on floating roof tanks, sub-surface injection systems, etc. c) Portable systems that are used for mounting discharging apparatuses on the storage vessel. Each of these traditional fire-fighting methods possess certain limitations that can include one or more of the following: their effectiveness in the application of the fire-fighting agent; the operating system requirements; the costs associated with the acquisition of the fire-fighting equipment and necessary peripheral equipment; the costs associated with the operation of the equipment, namely the volume of fire-fighting agent consumed; the time required to extinguish the fire and resume normal operations; and the associated damages related to property, plant, equipment and lost production. The limitations of long range fire-fighting methods discussed in a) above, include the following: a significantly higher minimum system pressure is required for the fire-fighting agent to reach the surface of the flammable liquid in the storage vessel; the costs are significantly higher in acquiring, maintaining and operating firefighting equipment operating at these higher pressures; the radial component in the stream velocity is allowed more time to develop, hence dispersing the fluid flow, thereby increasing the cross-sectional impact area of the fire-fighting agent, thus decreasing the concentration of the fire-fighting agent, and finally reducing the effectiveness of the fire-fighting agent in arresting the fire; the atmospheric winds surrounding the vessel and the convective gases arisir g from the fire also contribute significantly to the dispersion of the fire-fighting agent thereby reducing the effectiveness of the fire-fighting agent in arresting the fire; and - the longer trajectory of the stream of the fire-fighting agent from the discharge point to the target area increases the amount of air dragged into the stream of the firefighting agent and onto the surface of the flammable liquid thereby increasing the oxygenation of the fire. The Industry has generally sought to address the above performance limitations in arresting the fire by increasing the rate of application of fire-fighting agents from 3,OOOGPM to 5,OOOGFM to 10,OOOGPM, using a "surround and drown" approach. This method significantly increases the amounts of fire-fighting agents consumed and thereby the costs associated with extinguishing the fire. The limitations of fixed systems that are permanently installed on storage vessels, discussed in b) above, include the following: the foam chambers permanently installed on the roof of storage vessels, traditionally the first line of defense in the event of a fire, are highly vulnerable and are frequently rendered entirely inoperable in the initial phase of the conflagration when violent explosions may occur, and the Sub-surface injection systems can be rendered inoperable due to the effects of an explosion and more often due to clogging of the system. The limitations of portable systems that are used for mounting discharging apparatuses on the storage vessel, discussed in c) above, can include one or more of the following: they operate only with pre-mixtures of foam concentrate and water; they do not include apparatus for mixing the fire-fighting agents with a convening media; they are designed to discharge only one type of fire-fighting agent, for example foam; the foam discharge device is not detachable from the installation apparatus and therefore the installation of each discharge device requires its own installation apparatus; and they do not include an apparatus for the transportation of the entire system In view of the limitations of the traditional fire-fighting methods discussed above, thi applicants have developed a portable system for extinguishing fires in storage vessels containing flammable liquids that seeks to complement the positive performance aspects of these methods while addressing many of their core performance limitations There is therefore a need in the art for low-cost fire-lighting equipment that can be used to extinguish tires on or within a flammable substance in storage vessel. There is also a need for a system that is not permanently installed on the storage vessel so that the fire-fighting equipment is not damaged or destroyed by the explosions or conflagrations often associated with the initial stage of a lire There is also a need for a portable fire-fighting apparatus that does not attempt to spray fire-fighting agents from a remote position In addition, there is a need for lire-fighting apparatus that does not utilize costly high-pressure equipment. BRIEF SUMMARY This disclosure relates to the mounting or placement of one or more portable discharging apparatuses on the top perimeter of a storage vessel that contains a flammable substance. The portable discharging apparatus is adapted to issue a fire-fighting agent, at relatively low pressures, at the top of the burning storage vessel so as to extinguish a fire. The fire-fighljing agent may be applied to the surface of the burning liquid either indirectly, by issuing the firefighting agent against the inner walls of the storage vessel, or directly into the burning surface. The portable discharging apparatus may be installed on the storage vessel with a portable installation apparatus that can repeatedly install a plurality of portable discharging apparatuses on a burning storage vessel. The portable discharging apparatus is suitable for use with a wide variety of storage vessels including, without limitation, cylindrical storage tanks, spherical storage tanks, storage basins, railcars, tractor-trailers, ships, and barges. The portable discharging apparatus discharges fire-fighting agents, such as fire-fighting foams, onto the surface of a storage vessel. The portable discharging apparatus may also discharge the firsfighting agents directly onto a surface of the burning substance itself. The fire-fighting agint may comprise any number of well known fire-fighting mixtures, such as foam concentrates and water, foam concentrates and air, powders in a conveying media, chemical agents, colloid:;, gels or other agents. One or more different types of fire-fighting agents can be applied to a fin; either simultaneously, or one at a time. The disclosed system comprises one or more portable discharging apparatuses thai can be removably mounted on a flammable liquid storage vessel for discharging at least one firelighting agent. The system may further comprise one or more portable installation apparatuses for installing said one or more portable discharging apparatuses on said storage vessel. Tl system may further comprise one or more transportation apparatuses for carrying at least one portable fire-fighting apparatus and at least one portable installation apparatus. The system may further comprise one or more fire-fighting agent conditioning apparatuses for preparing tht formulated proportions of the fire-fighting agents and the conveying media. Only one portable installation apparatus is required to be transported to the fire sit£ to removably mount a plurality of portable discharging apparatuses onto a storage vessel wall The disclosed system further provides a method for extinguishing fires by removably attaching lone or more portable discharging apparatus to a storage vessel for discharging a fire-fighting agent; providing a mobile installation apparatus for removably attaching one or more said portable discharging apparatus on said storage vessel; and providing a transportation apparatus for carrying at least one portable discharging apparatus and one mobile installation apparatus. The portable discharging apparatus, the portable installation apparatus and other accessories for issuing fire-fighting agents may be readily transported to the site of a fire. The portable installation apparatus is deployed near the burning vessel and is used to place one or more of the portable discharging apparatuses on the top perimeter of a storage vessel wall after the conflagration has begun and the possible violent explosive phase has passed. Once the portable discharging apparatus is removably mounted or placed on the wall, the portable installation apparatus may be removed without hindering the continued operation of the portable discharging apparatus After this, the portable installation apparatus may be used to mount other portable discharging apparatuses to the vessel or other vessels. Only one source of pressurized fluid (i.e conveying media) need by used with multiple portable discharging apparatuses. A portable discharging apparatus can comprise a hollow circular tube, referred to as| a discharge duct A discharge attachment may be attached to the discharge duct to aim the flow of the lire-fighting agent in a specific direction The discharge attachment may be connected to the discharge duct at a mating junction to aim the flow of the fire-fighting agent in other directions. A flow aillimator is attached to the other end of the discharge duct and provides a supply pf lire-lighting agents to the discharge duct The flow collimator may also include a jet strearri enhancer plate, which increases the flow velocity of the lire-lighting agent, thereby enhancing the mixing of the tire-fighting agent with inflowing air to efficiently aerate the fire-fighting agent Specifically, in the embodiment of a foam concentrate mixed with water as the firelighting agent, the collision of the foam concentrate mixture with the in flowing air generates a higher quality of lire-lighting foam The portable installation apparatus can also comprise a plurality of extendible sections so that the length of the apparatus may be adjusted to correspond to the height of a particular storage vessel Specifically, by extending the length of the telescopic mast of the portable installation apparatus, the portable discharging apparatus (or apparatuses) may be mounted or placed on storage vessels of a variety of heights The portable installation apparatus may a|so have a foldable compact configuration so that it can be readily transported as a pre-assembled structure that may be quickly unfolded at the location of a fire for rapid deployment and operation. Another advantage of the disclosed system is its lower acquisition and operational costs These and other advantages of the system for extinguishing fires will become apparent to those of ordinary skill in the art from the following detailed description, which refers to the accompanying drawings.

DETAILED DESCRIPTION Two components of a fire-fighting system according to one aspect of the invention are depicted in FIGURE 1A: a portable discharging apparatus 100 and a portable installation apparatus 105. The portable discharging apparatus 100 may be removably coupled to the portable installation apparatus 105 so that one or more of the portable discharging apparatuses 100 can be mounted or placed on the top of a storage vessel 110. After the portable discharging apparatus 100 is mounted or placed on a storage vessel 110, fire-fighting agents are introduced into one end of the portable discharging apparatus and issued at the discharge end to extinguish a lire in the storage vessel The portable discharging apparatus 100 is comprised of several components, some of which are depicted in FIGURE 1A The depicted components include a receptacle duct 1 5, a How collimator 120, a discharge duct 125, and an arc-shaped flow discharge attachment HO. A supply hose 135 is attached to the flow collimator 120 to provide a supply of fire-fighting agents to the portable discharging apparatus 100. Also depicted in FIGURE 1A is a mixing apparatus 140, adapted to mix the fire-fighting agent concentrate with a supply of a conveying medic in the required proportions before it is fed into the supply hose 135. Accordingly, a conveyance media supply line 142, and a fire-fighting agent supply line 144, are connected to the mixing apparatus 140 The portable installation apparatus 105 is also comprised of several components, some of which are also depicted in FIGURE 1 A. These components include a telescopic mast 150L a base tube 165 and a pair of lateral support struts 170. The telescopic mast 150, the base tube 65 and the lateral support struts 170 are arranged in a generally triangular shape to provide a simple and stable support for erecting the portable installation apparatus 105. A support rod 155 witi a horizontal control rod 160 is affixed to the top of the telescopic mast 150. The support rod 155 and the support rod receptacle 175 join the portable discharging apparatus 100 to the poriable installation apparatus 105 Specifically, the portable discharging apparatus 100 may be removably coupled to the portable installation apparatus by inserting the support rod 155 into the support rod receptacle 175, which is permanently affixed to the receptacle duct 115. While the disclosed embodiment depicts a support rod 155 and a support rod receptacle 175 as the means by which the portable discharging apparatus 100 is attached to the portable installation apparatus 105, other suitable coupling devices will be apparent to one of ordinary skills, such as a hook and eye bolt connection, or other such means. Some of the other components of the portable installation apparatus 105 are stabilizing rods 180, which may be coupled to the telescopic mast 150 to provide stability and control during the installation of the portable discharging apparatus 100. Also depicted are tether lines 185, which are connected to the ends of the horizontal control rod 160 to provide further stability and control for orienting the portable discharging apparatus during the installation process. Another aspect of the portable fire-fighting apparatus depicted in FIGURE 1A is an installation control system 190 that controls the flow of hydraulic fluid to the portable installation apparatus 105. The installation control system 190 provides bi-directional hydriulic fluid flow through the hydraulic line 192 to the telescopic mast 150. As this hydraulic fluid is supplied, the telescopic mast 150 will be extended, thereby lifting the portable discharging apparatus 100 until it reaches the height of the storage vessel 110. Similarly, by removing hydraulic fluid from the telescopic mast 150, it can be retracted. According to one embodi nent of the invention, hydraulic fluid is injected into or released from the hollow cavity of the telescopic mast 150 to either expand or contract the telescopic mast 150. The hydraulic fluid flows into and out of the cylindrical cavity though the hydraulic line 192 with a quick disconnect coupler that functions as a check valve at an orifice at the base of telescopic mast 150. Th check valve operation is deactivated whenever the hydraulic line 192 is inserted into the quick disconnect coupler and activated when the hydraulic line 192 is removed from the quick disconnect coupler. Yet another aspect of the portable fire-fighting apparatus depicted in is a spacer member 194 that may be placed between the base tube 165 of the portable inst apparatus 105 and a wall of the storage vessel 110. The spacer member 194 is used to maintain a 10 ard distance between the portable installation apparatus 105 and the wall of the storage vessel during the installation of a portable discharging apparatus 100, thereby increasing the foru stability of the portable installation apparatus 105 as it raises or lowers the portable discharging apparatus 100 A fully extended portable installation apparatus 105 is depicted in FIGURE IB wherein the telescoping sections of the telescopic mast 150 are fully extended. As described above, the extension and retraction of the telescopic mast is controlled by the installation control system 190. According to the disclosed embodiment, the telescopic mast 150 of the portable installation 'ig. 1A llation apparatus 105 is comprised of a plurality of axially concentric sliding hollow cylinders. The inner hollow cylinders slide out of the top-end of the outer cylinder to extend the telescopic mast along the common axis to the length required to reach the upper perimeter rim of the storage vessel 110. Wide varieties of means are known in the art and are available to extend or contract the inner cylinders of the telescopic mast 150. After the portable discharging apparatus 100 is lifted over the edge of the storage vessel 110 and any fixed obstacles such as perimeter rails or cat walks, the telescopic mast 150 is lowered so as to locate the portable discharging apparatus 100 on the edge of the storage Vessel 110. After the portable discharging apparatus 100 is mounted or placed on the storage v 110, the portable installation apparatus 105 may be disengaged from the portable discharging apparatus 100 thereby leaving the portable discharging apparatus 100 mounted on the storage vessel 110. After the portable installation apparatus 105 has been used to place a portable discharging apparatus 100 on the storage vessel 110, it may be moved to different locations to successively mount a plurality of portable discharging apparatuses 100. FIGURE 1C depicts the assembly of the portable installation apparatus 105 and tlje portable discharging apparatus 100 according to one aspect of the invention. The portable installation apparatus 105 is shown with the telescopic mast 150 elevated at the distal end and supported using the support pedestal 198 for the purpose of facilitating the assembly process. A portable discharging apparatus 100 that has been mounted or placed on a storage vessel 110 is depicted in FIGURE ID. A supply hose 135 remains connected to the portable discharging apparatus 100 so that the fire-fighting agent can be applied continuously to th storage vessel 110. Thus, after the portable discharging apparatus 100 is mounted or placed on the top of the storage vessel 110, it can function independently to provide fire-fighting agents without the portable installation apparatus 105. More than one portable discharging apparatus 100 may be mounted or placed on <..> storage vessel 1 10. This embodiment is depicted in FIGURE IE where three separate portable discharging apparatuses 100 are mounted or placed on the storage vessel 110. This embodiment may be suitable for large surface-area vessels or for large fires, which may require the application of larger amounts of fire-fighting agents. :ssel Various embodiments of the portable discharging apparatus are depicted in FIGURES 2A through 2H. FIGURE 2A depicts a side view of a portable discharging apparatus 100 in further detail. As described previously, the portable discharging apparatus 100 may be comprised of a flow collimator 120, a receptacle duct 115, a discharge,duct 125 and a support rod receptacle 175. Also depicted in FIGURE 2A are a first rigid device 205 and a second rigid device 210. These rigid devices 205 and 210 work in unison to provide the required orientation for the portable discharging apparatus 100 and for maintaining the positional stability of the portable discharging apparatus 100 on the upper edge of the storage vessel 110 wall. The portable discharging apparatus 100 can be stabilized in this position using various other coupling mechanisms, such as spring loaded stabilizers, clamps, magnets and other means known in tlu art. This embodiment of the portable discharging apparatus 100 is suited for orienting the flow of the fire-fighting agent directly onto the surface of the burning liquid in the storage vessel I K The portable discharging apparatus 100 is also equipped with connection means, connecting bolts 215 in this embodiment, that allow the connection of alternate attachments to the port, discharging apparatus 100. ble Another component that may be used with the portable discharging apparatus 100 is ent arc-shaped flow discharge attachment 130, a representative embodiment of which is depicted in FIGURE 2B. The discharge attachment 130 is used, to direct the flow of the fire-fighting being discharged from the portable discharging apparatus 100 in a specific direction to extinguish a fire. The arc-shaped flow discharge attachment 130 of FIGURE 2B is designec to be connected to the end of the discharge duct 125 by joining the connecting bQlts 215 with the eye and bolt 220 of the arc-shaped flow discharge attachment 130. A wide variety of other means for attaching the arc-shaped flow discharge attachment 130 to the discharging duct 1(25 are known in the art and may be suitable for use with this invention, such as spring loaded tensors, buckles or other means. A portable discharging apparatus 100 that includes an arc-shaped flow discharge attachment 130 is depicted in FIGURE 2C wherein the portable discharging apparatus 100 is mounted onto the upper edge of the wall of a storage vessel 110. As the portable discharging apparatus 100 is mounted or placed on the storage vessel 110, the first rigid device 205 maintains an a space between the portable discharging apparatus 100 and the wall of the storage vessel 110 In addition, the second rigid device 210 secures the apparatus 100 onto the upper edge of the storage vessel wall 110. A supply hose 135 is connected to the flow collimator 120 to supply a mixture of fire-fighting agents to the receptacle duct 115. In FIGURE 2C, the embodiment of the portable discharging apparatus 100 with the arc-shaped flow discharge attachment 130 suited for orienting the flow of the fire-fighting agent against the inside wall of the storage vessel 110. Other embodiments, however, may be utilized to direct the fire-fighting agent in different directions. FIGURE 2D is a front view of the portable discharging apparatus 100 and an arcshaped flow discharge attachment 130. In FIGURE 2E, a side view of a portable discharging apparatus 100 is depicted. This embodiment incorporates a mounting loop 225 which is attached to the receptacle duct 115. This mounting loop 225 provides another means by which the portable discharging apparatus 10 may be mounted or placed on a storage vessel 110. Specifically, the portable discharging apparatus 100 may be raised'or lowered by attaching the mounting loop 225 to a hook that connected to a crane or other such conveyances. FIGURE 2F depicts an alternative embodiment for the portable discharging apparatus 100 with an arc-shaped flow discharge attachment 130, and the mounting loop 225 mounted or placed on the upper edge of the will of a storage vessel 110. In FIGURE 2G, a side view of a particular embodiment of the portable discharging apparatus 100 is depicted wherein a passage duct 240 is externally attached to the receptacle duct 115, passes into the discharge duct 125 and terminates concentrically at the output end of the discharge duct 125. The passage duct 240 is used to deliver an additional fire-fighting agen such as powders, colloids, gels, etc. within the discharge stream of the fire-fighting agent being delivered through the discharge duct 125. This embodiment permits the use of more than one fire-fighting agent simultaneously and orients the flow of the fire-fighting agents directly onto the surface of the burning liquid in the storage vessel 110. In FIGURE 2H, a side view of a particular embodiment of the portable discharging apparatus 100 and an arc-shaped flow discharge attachment 130 is depicted wherein the passage duct 240 extends concentrically through the interior of the arc-shaped flow discharge attachment 130. This embodiment permits the use of more than one fire-fighting agent simultaneously and orients the flow of the fire-fighting agents directly onto the inner wall of the storage vessel 110. In other embodiments, the passage duct 240 may be attached externally on the portable discharging apparatus 100 and the arc-shaped flow discharge attachment 130. More than on additional passage duct 240 may be attached to the portable discharging apparatus 100 for conveying and issuing a plurality of fire-fighting agents. FIGURE 3A depicts a longitudinal cross-sectional view of an alternative embodiment of the portable discharging apparatus 100, illustrating the positioning of the flow collimator 120 to the receptacle duct 115, as well as the mixing operations provided by these elements. After jhe fire-fighting agents pass through the flow collimator 120, they are aerated and passed from ihe receptacle duct 115 to the discharge duct 125. A mixture of foam concentrate is provided ir to a first end 305 of the flow collimator 120 by a supply hose 135. The conveyance of the mixti.re through the flexible supply hose 135 imparts a high degree of turbulence or non-uniform ve ocity in the mixture flow, shown by arrows 310, arriving at the first end 305. A higher level of turbulence in the flow results in a greater pressure loss along the length of the supply hose 35. The flow collimator 120 is used to pre-condition the mixture flow to obtain a higher degree of uniformity in the flow velocity of the mixture flow, as depicted by arrows 315, prior to passing through the jet-stream enhancer plate 325 with an end result of a better, more efficient and cost effective foam generation process. The flow collimator 120 may be comprised of a cylindrical tube of sufficient length to collimate the mixture. Upon reaching a second end 320 of the flow collimator 120, the foam concentrate mixture passes through a jet-stream enhancer plate 315. The jet-stream enhancer plate 325 increases the velocity of the flow and directs the foam concentrate mixture against the interior surface of the receptacle duct 115 thereby increasing the impact force between the foam concentrate mixture and the air 330, thus improving the foaming process. Furthermore, the flow of the foam concentrate mixture from the flow-collimator 120 into the receptacle duct 115 draws a supply of air 330 into the air input port 335, which is located at a first end of the receptacle duct 115. As the foaming agent is distributed throughout tl e interior of the receptacle duct 115, it is mixed with the air 330 that is drawn in from the ai input port 335 so as to generate a foam 340 that will be directed towards a second end of the receptacle duct 115. The embodiment depicted in FIGURE 3A utilized a flow collimator 120 and a jet- 20 stream enhancer plate 325 to generate the foam 340, however, one of ordinary skill in the art will realize that other arrangements may be utilized to generate a foam. FIGURE 3B depicts an alternative embodiment of the invention wherein the jet-stream enhancer plate 325, together with the collimator tube 120, are positioned at such a height, so as to reduce the vertical column of foam between the jet-stream enhancer plate 325 and the top of the receptacle duct 115, thus allowing a lower system pressure to overcome the back pressure of the foam 340 and thus obtain a higher fire-fighting agent flow at a lower pressure. This alternative embodiment incorporates many of the same components as the embodiment depicted in FIGURE 3A. The embodiment depicted in FIGURE 3B, however incorporates certain differences. Specifically, a much longer portion of the flow collimator is placed within the receptacle duct 115. In addition, air vents 350 are incorporated into the sidewall of the receptacle duct 115 in order to facilitate the mixing of the fire-fighting agen with the air 330. A perspective view of an alternative embodiment of the connection between a flow collimator 120 and a receptacle duct 115 is depicted in FIGURE 4. The flow collimator 1 attached to the receptacle duct 115 by a series of fins 400. The fins 400 secure the separat between the flow collimator 120 and the receptacle duct 115 resulting in an air input port 3 the first end of the receptacle duct 115. Also depicted in FIGURE 4 is a support rod receptacle 175 that is attached to the of the receptacle duct 115. The support rod receptacle 175 is designed to receive a suppo 155 that is attached to the telescopic mast 150 of the portable installation apparatus 105 (n shown) The portable installation apparatus 105 may be removably connected to the porta discharging apparatus 100 by inserting the support rod 155 into the support rod receptach The support rod receptacle 175 may also include a flared termination 410 that is designed guide the support rod 155 into the support rod receptacle 175 so that the portable dischar apparatus 100 may be readily coupled to and de-coupled from the portable installation ap] 105 Further, the support rod receptacle 175 and the support rod 155 depicted in FIGUR square cross-sectional areas adapted to prevent the rotation of the support rod receptacle with respect to the support rod 155. The specific embodiment depicted in FIGURE 4, als an oval point at the upper end of the support rod 155 for the purpose of facilitating the co Ois on $5 at icterior rod le 175. ;ng .ratus 4 have 75 shows pling of the support rod 155 with the support rod receptacle 175. Other forms of coupling may with corresponding mating cross-sections for the prevention of rotation such as a triangular cross-section, etc. Also depicted in FIGURE 4 is the horizontal control rod 160, which nay be used to stabilize and control the orientation of the portable discharging apparatus 100. The use of one embodiment of the portable discharging apparatus 100 is depicted ir FIGURES 5A-5C. In FIGURE 5A, a portable discharging apparatus 100 has been mounted or placed on the upper edge of the wall of a storage vessel 110. In the depicted embodiment, an arc-shaped flow discharge attachment 130 is attached to the discharging duct 125, so that the fire-fighting agent 500 is directed against the inside wall of the storage vessel 110. The firefighting agent flows down and in contact with the inside wall of the storage vessel 110 as a thick, continuous cascade, as depicted in FIGURE SB. As the fire-fighting agent 500 continues to be applied, it will spread uniformly over the surface 510 of the burning liquid contained in the storage vessel 110, as depicted in FIGURE 5C. Experience demonstrates that the disrupti effects of the fire on the fire-fighting agent layer, such as push back or disruption of the continuity of the fire-fighting agent layer is overcome by the back pressure that exists on the leading edge of the fire-fighting agent layer. This back pressure is generated from the location where the fire-fighting agent flows down the inside wall of the storage vessel 110 and comes in contact with the liquid contained in the storage vessel. Eventually, as the fire-fighting agent continues to be issued from the portable discharging apparatus 100, the entire surface 510 of the burning liquid contained in the storage vessel 110 will be covered with the fire-fighting agent 500, thus cutting off the oxygen supply and extinguishing the fire. In another embodiment of this invention, fire-fighting agents may be used also to extract heat from the burning liquid contained in the storage vessel 110. In this manner, the temperature of the burning liquid is lowered beneath the ignition point thus contributing to extinguishir g the fire. Another embodiment of the portable discharging apparatus 100 is depicted in FIGURES 6A-6C. In FIGURE 6A, a portable discharging apparatus 100 is mounted or placed on lie upper edge of the wall of a storage vessel 110. In this embodiment, however, the arc-shaped flow discharge attachment 130 is not utilized. Accordingly, the fire-fighting agent 500 that is discharged from the discharge duct 125 is aimed directly onto the surface 510 of the burning liquid contained in the storage vessel 110. Eventually, as the fire-fighting agent continues to be issued from the portable discharging apparatus 100, the entire surface 510 of the burning liquid contained in the storage vessel 110 will be covered with the fire-fighting agent 500, thus cutting off the oxygen supply and extinguishing the fire (FIGURES 6B & 6C). In this embodiment experience indicates that the disruptive effects of the fire may destroy the continuity of the ~irefighting agent layer thereby permitting the access of oxygen and delaying or preventing the extinction of the fire. In this embodiment it is recommended that several portable discharging apparatuses be mounted using only one portable installation apparatus 105 and used simultaneously to ensure the successful extinction of the fire. The two embodiments depicted in figures 5A-5C and 6A-6C, and other embodimen specified here, can be used simultaneously given the flexible nature of the portable discharging apparatus 100 and the range of geometries available for the flow discharge attachments. In another embodiment of this invention, fire-fighting agents may be used also to ex heat from the burning liquid contained in the storage vessel 110. In this manner, the tempe of the burning liquid is lowered beneath the ignition point thus contributing to extinguishing fire. A representative embodiment of a mixing apparatus 140 is depicted in FIGURE 7. described earlier with reference to FIGURE 1 A, the mixing apparatus 140 mixes a conveyi media with a concentrated fire-fighting agent, such as a foaming mixture, and feeds this mi into a supply hose 135. In FIGURE 7, a conveyance media supply line 142 is provided to end 700 of the mixing apparatus 140. A pressure gauge 705 may be attached to the conve media supply line 142 to measure pressure. Within the mixing apparatus 140 is an inspirat 720.

The inside diameter of the fire-fighting agent concentrate inlet 730 is selected a priori to provide the required proportions of fire-fighting agent concentrate and conveying media. A fire-fightir agent supply line 144 is attached to the fire-fighting agent concentrate inlet 730 to provide fighting agent concentrate to the mixing apparatus 140. Thus, at the second end 735 of th s not ract ature the As 8 ture first ance g fire- mixing apparatus 140, a mixture of a conveying media and fire-fighting agent concentrate is provided to a fire-fighting agent supply hose 135.
