微型燃气轮机冷热电联供系统的热经济性分析

Thermal economic analysis on CCHP system based on micro-turbines

在分析系统成本构成的基础上,运用热经济系数评价模型对系统的设备投资成本、运行成本和燃料成本进行了计算,分析了设备投资成本、燃料成本和运行时间对系统热经济系数的影响。结果显示,燃料成本和运行时间对系统的热经济系数影响较显著,降低燃料单价和增加系统每天运行时间会减小系统的热经济性系数。

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.
