FIELD OF INVENTION The invention relates to methods., and apparatuses for carrying out combustion for industrial application. More particularly, the invention relates to a gravity-fed oil- fired burner capable of carrying out combustion without a fuel oil pressurizing pump. conTbustion air blower, atomizer tip, and swirelers. PRIOR ART. Many industrial applications require large-scale generation of heat from burners. Various types of burners are available world wide for industrial applications. Generally oil pumps and blowers/ fans with associated control systems are employed to pressurize the fuel oil and to supply the combustion air at required parameters. However there are many applications where there are limitations in employing blowers and pumps due to various statutory and/ or safety restrictions. As on today many industrial burners of different capacities are available, all of which are required to be operated with moderate fuel oil pressures and forced draft combustion air with precisely machined atomizer tips. They further require swirlers of calculated geometry and shape and restricted operational flexibility. Requirement however exists where industrial burners warrant generation of heat without any or none of the auxiliary equipment such as described hereinabove. Such requirements may further call for a vertically upward oil firing as opposed to conventional horizontal firing. Accordingly, there is a need of an oil burner with the above-mentioned unique features, which the present invention primarily addresses. OBJECTS OF THE INVENTION. An object of the present invention is to provide a gravity fed oil fired burner which operates"without any externally driven/assisted fuel oil pump. Another object of the present invention is to provide a gravity fed oil fired burner which operates without a combustion air blower, and/or without fuel-oil atomizer tip, wind box. Yet another object of the present invention is to provide a gravity fed oil fired burner which operates without any electrical power, both during start up and operation. A still further object of the present invention is to provide a gravity fed oil-fired burner which is adaptable to generate a vertically upward firing configuration for improved combustion. SUMMARY OF THE INVENTION. Accordingly there is provided a gravity-fed oil fired burner for generation of heat, characterized by a burner cup receiving oil from an oil tank disposed at a height higher than the burner cup ; a first pipe line for delivery of oil to the burner cup via an oil entry port, an atomizing tube being provided in the burner cup for atomizing the oil; a second pipe line configured at an opposite end in respect of the first pipe line , and being flowably connected to the burner cup for supply of an atomizing medium; at least one first isolation valve to isolate the oil flow followed by .a flow control valve to control the oil flow rate is disposed on the oil-flow path, and in that a regulating valye. preceded by a second isolation valve is provided on the flow path of the atomizing medium, the cup, and the tube arrangements being housed in a burner pipe BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS. Figure-1- shows a block diagram of a gravity-fed oil-fired burner according to the present invention. DETAILED DESCRIPTION WITH REFERENCE TO THE DRAWING. The nature of invention will be clear from the following descripfions with reference to the accompanying Figure 1. An oil entry port ( 1) for oil entry is configured on a burner cup (3). Oil is transported via first a first pipeline (2) to the burner cup(3). At least one first isolation valve(4) is disposed on the oil delivery path to isolate the oil flow. A flow control valve (5) to control the required oil flow rate is provided immediately adjacent to the first isolation valve (4). The cup (3) is fitted with an atomizing tube(6). An atomizing medium is carried to the burner through a second pipe line (7). A second isolation valve (8) to isolate the atomizing medium and a regulating valve (9) to regulate the atomizing medium is successively disposed on the flow-path of the atomizing medium. The cup (3) and the tube arrangement (2, 7) are housed in a burner pipe (10). The level of the fuel oil is maintained to be just above the atomizing tube(6). fhis level is maintained constantly by setting the opening of the control valve (5). The opening percentage is governed by the height of a fuel tank ( not shown) and the design parameters of the first and the second pipelines ( 2, 7). We Claim: 1. A gravity-fed oil fired burner for generation of heat, comprising a burner cup (3) receiving oil from an oil tank disposed at a height higher than the burner cup (3); a first pipe line (2) for delivery of oil to the burner cup (3) via an oil entry port (1), an atomizingJube_(6) being provided in the burner cup (3) for atomizing the oil; a second pipe line (7) configured ai an opposite end in respect of the first pipe line (2), and being flowably connected to the burner cup (3) for supply of an atomizing medium; characterized in that at least one first isolation valve (4) to isolate the oil flow followed by a flow control valve (5) to control the oil flow rate is disposed on the oil-flow path, and in that a regulating valve (9) preceded by a second isolation valve (8) is provided on the flow path of the atomizing medium, the cup (3) and the tube arrangements ( 2, 7) being housed in a burner pipe (10). 2. The burner as claimed in claim 1, wherein location of the oil storage tank causes gravity-feed of oil adequately to the burner cup (3). 3. The burner as claimed claim 1 wherein combustion air is self aspirated atmospheric air. 4. The burner as claimed in claim 1, wiierein the atomization medium could be either steam or compressed air. 5. The burner as claimed in claim 1, wherein the level of the oil in the cup is maintained by a preset flow control valve (5). 6. A gravity-fed oil fired burner for heat as substantially described Hereinabove and illustrated with reference to the accompanying drawing. This invention relates to a gravity fed oil fired burner for generation of heat having technical features (inventive features) of a) receiving oil from an oil tank disposed at a height higher than the burner cup; b) delivering oil by a first pipe line (2) to the burner cup via an oil entry port (1) for atomizing the oil through an atomizing tube (6); c) supplying atomizing medium by a second pipe line (7) disposed at an apposite end of the first pipe line (2) being flowably connected to the burner cup (3); with distinguished characterized features over prior art d) of control means of oil flow rate disposed on oil flow path consisting of first isolation valve (4) to isolate the oil flow followed by a flow control valve (5); e) a regulating valve (9) preceded by a second isolation valve (8) disposed on the flow path of the atomizing medium; f) a burner pipe (10) housing the cup (3) and tube arrangements (2,7). The technical features (a) to (f) of the invention is performed to generate heat by the burner on maintenance of controlled flow of oil and atomizing medium through distinguished technical features (d) to (f).
