THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE NATURE OF THIS INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED

This invention relates to a device generating electrical power from thermal energy obtained from liquefied petroleum gaa (LPG) or compressed natural gas (CNG). The use of one of these expressions will also be applicable to the other in this specification.
Normally, while using an LPG cylinder only about 30 % of heat is usefully utilised to heat food while the balance about 70% energy is wasted, by passing on to atmosphere.
On the other hand, use of the device proposed herein serves to harness about 40 % of the energy which would otherwise have been wasted and convert such energy into electrical energy.
The device, for generating electrical power from thermal energy obtained from liquefied petroleum gas or

compressed natural gas, according to this invention comprises ft plurality of chambers arranged in close juxtaposition in circular array, the said chambers being sandwiched between two static frames provided with first and second outlets, said chambers being circularly driven by a prime mover, each such chamber, while rotating, successively (i) receiving atmospheric air from a blower through an inlet orifice and a first m atch ing inlet opening in the frame, at an air intake zone, while simultaneously evacuating the spent gases in the chamber through an outlet orifice in the chamber and the second outlet, at an exhaust zone; (it) receiving, at a gas intake zone, liquefied petroleum gas from a source, through the said inlet orifice and a second matching inlet opening in the frame, to mix with the air already in the chamber (iii) igniting the air-gas mixture in the chamber at an ignition zone, to result in combustion, releasing thermal energy and building up pressure, the gases of combustion being directed through the outlet orifice and the first outlet to a

turbine impeller/blade for driving the same, the said turbine being coupled to an electrical generator for generating electrical power. This invention will now be described with reference to the accompanying drawings which illustrate by way of example, and not by way of limitation, one of possible embodiments of the device proposed herein*
Fig. 1 illustrating the embodiment in plan Fig.2 illustrating the embodiment in side elevation Figs. 3 to 6 illustrating the said embodiment in sectional elevation at various stages thereof
A plurality of chambers C are arranged in close juxtaposition in circular array, the said chambers being sandwiched between two static frames F provided with first and second outlets S1 and S2.
The chambers C are circularly driven by a prime mover (not illustrated as this can be readily visualised).

Each such chamber, say, the chamber CI. while rotating, successively receives atmospheric air from a blower through an inlet opening Fl in the frame F and a matching in let orifice 01 in the chamber CI, at an air intake zone Zl, while, simultaneously, evacuating the spent gases in the chamber (collected from the completion of the previous procedure) ^trough outlet orifice 02 in the chamber CI and a matching outlets 2 in the frame F at the exhaust zone.
Thereafter, as the chamber CI rotates further, it receives at a gas intake zone Z2, liquefied petroleum gas or compressed natural gas from a source (such u a cylinder), through the said inlet orifice 01, to mix wtA the air ah-eady in the chamber. The said gas entors the said orifice 01 a matching inlet opening F2 in the frame F.

Subsequently, the chamber CI reaches the ignition zone Z3 at which ignition of the air-gas mixture in the said chamber takes place by means of a spark plug P or heat source. Combustion of the said air-gas mixture takes place releasing thermal energy and building up pressure.
By this time the chamber CI, during rotation, would have reached the power zone Z4 where the gases of combustion are released through the outlet orifice 02 and the matching outlet SI in the frame F. These gases are then directed to a turbine coupled to a generator (not illustrated s thee can be readily visualised). The turbine is driven by the gases emerging at the outlet SI. The turbine is coupled to a generator for generating electric power.
All the remaining chambers C undergo the same procedure as the chamber CI identified above.

Preferably, a cushioning layer L made of a beat resistant material, such as, asbestos, is provided between the array of chambers and the frame.
