摘要
热电联产是一种热能、电能同时生产的能源利用形式。它将高品位的热能用于发电,低品位的热能用于集中供热,既提高能源的利用效率,又减少了环境污染。燃气热电联产(CHP)系统则是利用燃气锅炉和供热汽轮机的热电联产供应系统。从能量的有效利用方面对CHP系统的各个环节进行了分析计算,并结合实例,将它与燃气热电分产系统进行比较。结果表明,CHP系统的可用能效率高,节能、经济,同时还可以减少环境污染。
A combined heat and power generation （CHP） system produces heat and power at the same time. It uses high-grade heat for power generation and low grade heat for heating, and can therefore increase energy utilization efficiency and reduce pollutant emissions. A gas cogeneration system is equipped with gas-fired boilers and gas turbines. In this paper, the effective energy utilization of a gas cogeneration system was discussed, and a calculation of all the sections of the CHP system was carried out. A comparison between the CHP system and a conventional thermal power system was made. It is verified that the exergy in the CHP system is well used, and the CHP system can save more energy, is more economic, and can reduce pollutant emissions.
