Abstract
A gaseous fuel combustor for a Stirling engine includes a shell mounted on the engine, and air inlet and exhaust ports formed in the shell. An annular cylindrical recuperator communicates with the inlet and exhaust ports for preheating the combustion air with the heat from the exhaust. An annular burner surrounds the dome shaped engine heater head for mixing gaseous fuel with the air and burning it at the outer peripheral edge of the heater head. The combustion products converge upwardly in a narrow space between a ceramic partition and the heater head dome so that the heat flux is constant. The combustion products exhaust through a axial hole in the center of the ceramic partition and travel back outward over the top of the partition to the annular recuperator.
