The paper presents a brief analysis of the factors that influence the exergy efficiency of the general energy flow of gassteam combined cycles with pressurized circulating fluidized beds. Presented are also their optimized parameters obtained by some compound optimization method of calculation. Optimization results show that the exergy efficiencies of these systems are superior to these of conventional steam turbine or gas turbines.
