| Abstract: | It offers a method of exergy-economic coefficient, analyzes natural gas co-generation system, power system and natural gas combined heat and power system, and also calculates the exergy-economic coefficients of three systems, analyzes them and then obtains that natural gas co-generation system has higher thermal economy. Further this paper analyzes the sensitivities with different natural gas's prices and then gets their exergy-economic coefficient.Figs 4, tables 8 and refs 5. |
