Fluidized bed combustion (FBC) is well suited for firing various sorts of hard coal and lignite, and co-firing coal with other fuels (wastes, biomass), and it is characterized by low air pollution. Conventional pressurized fluidized bed combustion (PFBC) power plants operate at the nominal combustion temperature 870°C for optimal sulfur capture. Since this temperature is well below the turbine inlet temperature of the current gas turbines, a topping gas turbine cycle has been proposed that can enhance the cycle efficiency of the conventional PFBC plants. In the topping cycle a recuperated gas turbine fuelled with natural gas utilizes the coal combustion heat to preheat the compressed air before the gas turbine combustor. An influence of such an "external heat recuperation" on efficiency, power and total fuel costs for various proportions of used coal and natural gas in the proposed advanced PFBC plant has been analyzed.
