IMPROVING COAL-FIRED POWER-GENERATION BY INTEGRATING PFBC AND GAS-FIRED COMBINED CYCLES IN A HYBRID PROCESS

Two hybrid combined cycle electrical power generating schemes burning coal and natural gas were examined using the ECLIPSE chemical process simjlator. The results of these simulations are presented and analyzed . Comparison is made with conventional power generation technologies. Two additional pieces of work are included. The first examines the eff ect of the hot gas filtration operating conditions on the hybrid combi ned cycle efficiency and the second calculates the allowable increase in capital cost for a specified improvement in power plant efficiency while maintaining the same cost of electricity.
