The comparison between the CHP system and the separate generation system was done. Finally, the influence of the main factors, heat recover ratio, price ratio of electricity/natural gas and normalized cost, on the economy of the CHP system was studied.

• 对CHP联产系统的一次能耗率(PER)和无最纲费用比进行了计算,并与分产系统作了对比,最后讨论了微型燃机回热度和电/气价格比对CHP联产系统经济性的影响。
