摘要
提出系统经济系数方法,对天然气热、电、冷三联供系统,天然气发电系统和天然气热电联供系统进行分析,计算出三系统的经济系数,对其进行比较分析,指出天然气热、电、冷三联供系统具有较高的热经济性。进一步对天然气价格进行灵敏度分析,得出三系统在不同天然气价格下的经济系数。
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.
