A pulse combustion apparatus is described which includes: a combustion chamber; an exhaust system including an exhaust pipe forming a resonant system with the combustion chamber and a generally cylindrical exhaust cushion chamber downstream of the exhaust pipe for receiving combustion gases from the pipe and communicating with an exhaust outlet form the apparatus; means for delivering successive fuel charges to the chamber; combustion air supply means including a housing of generally rectangular, box shape enclosing the exhaust cushion chamber and defining a space around the chamber through which combustion air can be conducted from an air inlet to the combustion chamber for permitting heat exchange between exhaust gases in the exhaust cushion chamber and the combustion air when the apparatus is in operation, for pre-heating the combustion air; means adapted to cause combustion air to flow in a convoluted path in the space for promoting improved heat transfer between exhaust gases in the chamber and the combustion air, the means comprising partitions between the exhaust cushion chamber and housing extending generally longitudinally of the exhaust cushion chamber and arranged to cause the combustion air to flow alternately from end to end of the chamber in the convoluted path.
