The performance of combined cycle power plants integrated with advanced air- and oxygen-blown entrained gasification systems as well as with advanced oxygen-blown fixed bed gasifiers will be presented. The performance and cost of such plants using near-term gas turbine technology will be compared to the performance of conventional coal-fired steam plants with FGD. The integrated combined cycle plant appears attractive at today’s gas turbine firing temperatures. Further benefits from advanced gas turbine operating conditions on the performance and economics of such plants and the rationale for these performance trends will be discussed.
