Patent ID: 8132416

Claim:
A method for producing hydrocarbon combustion gas for the production of energy comprising: providing a hydrocarbon combustion gas generator, which comprises a first combustion chamber having an inlet end and an outlet end, a second combustion chamber having an inlet end and an outlet end, an injector plate between the outlet end of the first combustion chamber and the inlet end of the second combustion chamber separating the first combustion chamber from the second combustion chamber, wherein the inlet end of the second combustion chamber is in fluid communication with the outlet end of the first combustion chamber through the injector plate, and a heat exchanger means for cooling the first and second combustion chambers and for converting cooling water to steam, wherein the cooling water and steam are maintained separate from combustion gases produced by the first and second combustions; metering a hydrocarbon fuel which comprises particles of hydrocarbon-containing material into the first combustion chamber; separately metering an oxidizer into the first combustion chamber to achieve an incomplete combustion of the fuel in the first chamber; metering into the second combustion chamber the incomplete combustion product produced in the first combustion chamber through the injector plate; and metering additional oxidizer into the second combustion chamber through the injector plate to further combust the fuel in the second chamber.
