一、问题的提出我国在“七五”期间将加强城市集中供热的建设。采用热电联产的方式为集中供热提供热源,不但可以成倍地提高热能利用率,节约能源,而且还能显著减少大气污染,故它是城市设施现代化的途经之一。在我国北方地区,采暖期为4—6个月,有的城市正计划建设大型热电站。对于仅供采暖用热的热电站,可选用哈尔滨汽轮机厂制造的C145/200—130/535/535型20万千瓦采暖抽汽冷凝式汽轮机。但对某些计划建设的热电站不仅要求采暖供热,还要求供工
First, the issue raised China’s “seven five” period will strengthen the construction of urban central heating. It is one of the ways of modernizing urban facilities by using CHP to provide heat for central heating, which can not only double the heat utilization rate and save energy, but also significantly reduce air pollution. In northern China, heating period of 4-6 months, and some cities are planning to build large-scale thermal power station. For heating only for thermal power plant, choose Harbin Turbine Factory C145 / 200-130 / 535/535 200,000 kilowatts heating extraction condensing steam turbine. However, some planned construction of thermal power plants not only require heating and heating, but also for the job
