In order to establish the combined-cycle of CCHP (combined cool heat and power) using natural gas and biomass as fuels

a series of thermodynamic parameters and boundary condition has been tested on ASPEN PLUS simulation plat.And the conversion process of thermal and power of the key part in the system have been discussed

as well as the distributions of material flow rate

pressure and temperature in the system.Besides

the effects of the inputting parameters on economic

technical and emission performance have been studied.The results show that the proportion of natural gas and biomass gasification has a very important impact on exhaust temperature and pressure of gas turbine

waste heat boiler.So does the energy gradient.Under certain blend ratio

with the increase in air

exhaust temperature of gas turbine and waste heat boiler will obviously decline.Though the total capacity utilization increases

relatively energy-saving rate

equivalent exergy efficiency and economy exergy efficiency of the system continue to decreases.And

the air temperature and the ambient temperature will result in overall energy efficiency of the system improved.
