40.石炭・バイオマス火力発電プロセスシミュレーターの開発

抄録

Advanced process simulator for pulverized coal fired power station has been developed to predict coal quality impacts on economical performance. Process simulation logics of a 350MW coal fired power plant are built on ASPEN PLUS, and their process characteristics are calculated. In this study, effects of coal quality and biomass blending on performance of power plants were studied. Calculation results of power generation efficiency for coals show good agreement with actual plant data. It is found that biomass co-combustion is decreased power generation efficiency.
