| 摘 要： | 介绍了微型燃气轮机(微燃机)冷热电三联产系统(三联产)的构成,利用热力学理论对三联产系统在额定工况下的产品成本单价进行了分析,计算了在不同天然气成本单价和微燃机不同工况下排气(烟气)余热利用率ηy的发电量成本单价和制冷量成本单价。计算表明,发电量成本单价随ηy的增加而减小;天然气成本单价增加会增大发电量成本单价;提高ηy对降低发电量成本单价有作用;制冷量成本单价随天然气成本单价增加而增加;ηy在70%后对单位制冷量成本单价的影响降低。

| Abstract: | The structure of cool,heat,and electricity co-generation system has been presented.By using the thermodynamic theory,the unit price of product cost in said co-generation system under rated working condition has been analysed,the unit price of generation cost and refrigeration cost under different unit price of natural gas cost and different recovery rate of residual heat in exhaust gas under different operating conditions of the micro gas turbine being calculated.Results of calcualtion show that the unit pr... |
