A power generation system () and a method of generating power. In one embodiment of the system shown in FIG., a gasification subsystem () is configured to convert a carbonaceous fuel to fuel suitable for combustion in a gas turbine (). A first power generation cycle () includes the gas turbine () coupled to receive fuel from a gasifier (). A first Rankine cycle () is coupled to receive thermal energy from at least the first power generation cycle () and generate power with a first vapor turbine (). A second Rankine cycle () is coupled to receive thermal energy from the gasification subsystem () or the first power generation cycle () and generate power with a second vapor turbine (). In an associated method, syngas () is generated and processed to remove components therein. Power is generated in a first turbine () with the processed syngas (). Power is generated in a second turbine () with heat recovered from exhaust produced by the first turbine (). Power is generated in a third turbine () with heat recovered from the syngas ().

Power generation system incorporating multiple Rankine cycles

A system and method for producing multiple syngas products. In one embodiment (FIG.) a syngas producing system () includes a gasifier () and a hydrocarbon steam reformer (). The gasifier () is configured to react a solid or liquid carbonaceous material () and provide a first syngas product (). The reformer () is coupled to receive sensible heat from the first syngas product () and drive an endothermic reaction in which a second syngas product () is produced from a liquid or gaseous hydrocarbon supply (). In a method of processing fuel, a solid or liquid carbonaceous material () is provided to a gasifier () in the form of a slurry, which is converted into a first syngas product () in an exothermic reaction. A liquid or gaseous hydrocarbon supply () receives sufficient sensible heat generated during the exothermic reaction to convert the liquid or gaseous hydrocarbon supply () into a second syngas product ().
