Rijke type combustion arrangement and method

Abstract

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 several steps. In a first step, a mixture of fuel and oxidant is ignited 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 the combustion zone or zones (16, 18, 98, 122) to provide a low pressure area within the combustion zone or zones (16, 18, 98, 122). In a second step, said low pressure area causes partial return of the combusted fuel/oxidant mixture from a location remote of the combustion zones (16, 18, 98, 122) and also causes 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 the first step 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.
