Thermal economic analysis on CCHP system based on micro-turbines

Based on the analysis of the system cost construction, calculates the equipment investment cost, running cost and fuel cost with the thermo-economic factor evaluation model, and analyses the influences of equipment investment cost, fuel cost and running time on the thermo-economic factor of the system. The results show that the fuel cost and the running time have important influences on the thermo-economic factor, and decreasing the unit fuel price and increasing the running time can reduce the thermo-economic factor of the system.
