A system for burning particulate combustible fuel to produce a pressurized gas for operating a gas turbine is described comprising: a housing having side wall means forming a primary combustion chamber, a secondary chamber and a choke opening for reduced size between the primary combustion chamber and the secondary chamber. The secondary chamber is in fluid communication with the primary combustion chamber through the choke opening. The end of the primary combustion chamber opposite the choke opening is closed by end wall means. The end of the secondary chamber opposite the choke opening has an outlet opening for the passage of hot gas therethrough. A gas turbine is coupled to the outlet opening of the secondary chamber for operation by the gas passing through the outlet opening. A fuel opening is 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 such that the particulate fuel travels toward the choke opening in a helical path around the inner wall of the primary combustion chamber for burning therein for the production of hot gas under pressure for flow through the choke opening to the secondary chamber.
