Abstract:
1. An integrated power generation and fuel synthesis process, comprising: (a) providing a fuel synthesis unit to process a feedstock to produce a synthesis gas comprising hydrogen; (b) providing a gas turbine engine and an electrical generator, the gas turbine engine coupled to the electrical generator for generating electrical power, the gas turbine engine comprising (c) compressing an oxidant in the compressor to produce a compressed oxidant stream, and supplying the compressed oxidant stream to the trapped vortex combustor; (d) mixing the synthesis gas with the compressed oxidant stream to form a lean premixed fuel and oxidant mixture; (e) feeding the lean premixed fuel and oxidant mixture to the trapped vortex combustor in a bulk fluid flow direction at a bulk fluid velocity in excess of the speed of a flame front in the lean premixed fuel and oxidant mixture, wherein the bulk fluid velocity of the lean premixed fuel and oxidant mixture flows to said trapped vortex combustor is at least 105 meters per second, and wherein an additional flow of synthesis gas is injected into said trapped vortex combustor as a vortex stabilization jet; (f) combusting the fuel in the trapped vortex combustor, to create a hot combustion gas exhaust stream; and (g) expanding the hot combustion gas exhaust stream in the turbine to produce shaft power, said shaft power turning the electrical generator to produce electrical power.
