摘　　要：为克服传统鳗鱼养殖场供热、供电的缺陷,提出了以微型燃气轮机为原动机的热电联产新型供热、供电模式。在计算鳗鱼养殖场耗热量、耗电量的基础上,对热电联产与传统热电分产进行热力学分析,比较了两者的一次能利用率和火用效率,热电联产的一次能利用率是传统热电分产的1.84倍,而火用效率是传统热电分产的1.43倍。Intensive farming of eel requires favorable water quality and temperature conditions, so it requires reliable power supply for oxygen aerating and heat supply in order to maintain the water temperature. Separate Generation of Heating and Power was adopted in traditional eel farming. However, it leads to the following resuits： coal-fired boilers pollute environment severely; dissolved oxygen reduces because of the unreliable power supply in rural area. In order to overcome shortcomings of traditional eel farms, Combined Heating and Power with micro turbine is presented. Based on the calculation of heat consumption, power consumption, thermodynamic analysis is discussed between Combined Heating and Power and Separate Generation of Heating and Power. Primary energy ratio and exergy efficiency are compared between them, primary energy ratio of Combined Heating and Power is 1.84 times of Separate Generation of Heating and Power, and exergy efficiency is 1.43 times of Separate Generation of Heating and Power.
