A process of producing heat energy for use in heat exchange with other fluids and substances so as to impart said heat energy to said fluid or substances which includes the steps of: (i) igniting a mixture of fuel and oxidant in a combustion zone or zones (16, 18, 98, 122) to create a combusted fuel mix which in the form of Shockwaves are carried away from Ihe combustion zone or zones (16, 18, 98, 122) to provide a low pressure area within the combustion zone or zones (16, 18, 98, 122); and (ii) said low pressure area causing partial return of the combusted fuel/oxidant mixture from a location remote of the combustion zones (16, 18, 98, 122) and also causing a new change of oxidant/fuel mixture to be transferred from the combustion zone or zones (16, 18, 98, 122) whereby incoming and returning hot gases are caused to ignite automatically without the aid of the ignition device used in step (i) thereby causing a series of pulses or oscillations of successive return of hot gases and further.changes of fuel/oxidant mixture to provide a process of production of energy which is self-sustaining and continuous. A combustion arrangement for use in the process described above having at least one combustion chamber or space (16, 18, 98, 122) having an associated ignition device (53A) wherein the combustion chamber or space (16, 18, 98, 122) has one or more inlets or entrances (66, 131, 132) and a flame retainer in the form of a porous membrane (28, 97, 123) located In or adjacent to the or each inlet or entrance (66, 131, 132) and one or more conveying zones (22, 100, 101, 120) located adjacent the porous membrane (28, 97, 123) for conveying hot gases away from the combustion chamber or space (16, 18, 98, 122). |
