Abstract
A system and method for operating an integrated gasification combined cycle (IGCC) gas turbine system that utilizes the fuel stream as a means of controlling the operation of the IGCC to achieve a target output and efficiency. The methods and systems enable the IGCC to be operated at reduced output, but without a corresponding drop in efficiency as compared to prior art gas turbine systems. Conversely, the IGCC may be operated at higher outputs. The methods and systems achieve the target output and efficiency by adjusting the chemical potential energy, sensible energy, or both of a fuel stream entering the combustion turbine. The chemical potential energy and sensible energy may be manually or automatically controlled.
