摘要：
The combination of gas turbine and water-/steam cycle is a proper alternative to increase the efficiency of power plants. Coal fired power plants can be designed as reactors with pressurized coal gasification, pressurized coal dust combustion or a pressurized fluidized bed combustion to realize these plant design. Mathematical modeling and simulation are used to support the development of new power plant concepts, e. g. pressurized fluidized bed combustion. In this paper a one-dimensional model for a pressurized fluidized circulating bed combustion Fewer plant is presented. The modeling structure allows to vary different parameters to identify the particular influence on the overall plant behavior. The model is enlarged by a more detailed balance for limestone. After describing the theoretical background of the influence of added limestone rate on the emissions of sulfurdioxide is shown.
