This paper describes an apparatus for burning particulate combustible fuel to produce a pressurized gas for operating a gas turbine. It comprises: a housing having side wall means forming a generally cylindrically shaped primary combustion chamber, a secondary chamber and a choke opening of reduced size between the primary combustion chamber and the secondary chamber; a fuel opening formed through the side wall means of the primary combustion chamber near the end wall means for introducing a particulate fuel under pressure therein generally tangentially to the inner wall of the primary combustion chamber and transverse to its axis; a plurality of spaced apart tuyere openings formed through the side wall means of the primary combustion chamber; at least one quench gas opening formed through side wall means of the choke opening intermediate its ends for introducing a quench gas into the choke opening for cooling the hot gas flowing.
