Kitchen, J A

A pulse combustion apparatus is described comprising: a combustion chamber having inlet means for fuel charges and an outlet for exhaust gases remote from the inlet means; an exhaust pipe extending from the exhaust gas outlet and forming a resonant system with the combustion chamber; and, means operable to initiate combustion in the chamber; wherein the fuel charge inlet means comprises: a fuel gas distributor forming a bluff body within the combustion chamber and defining an annular combustion air passageway around the body. The distributor has a fuel inlet for connection to a fuel supply externally of the combustion chamber, and discrete fuel gas outlets extending around a peripheral surface of the bluff body and from which individual gas streams issue when the apparatus is in operation; and, valve means for admitting air to the air passageway during low pressure portions of the pulse combustion cycle; whereby, at each cycle, a striated charge having streaks of gas and air is introduced into the combustion chamber.
