集中供热,热电合产是合理利用和节约能源的重要途径,是建设现代化城市的有效措施。据有关资料介绍,许多技术发达国家都在大力发展热电联产集中供热。其中苏联居于首位,据1977年统计,苏联热电联产的供热能力达21万百万大卡/小时,供热汽轮机组占汽轮机组总容量的35％。其次是西德, Centralized heating, combined heat and power generation is an important way to rationally use and save energy, and is an effective measure to build a modern city. According to relevant information, many technologically advanced countries are vigorously developing cogeneration central heating. Among them, the Soviet Union ranks first. According to statistics from 1977, the heating capacity of the Soviet Union’s cogeneration system reached 21 million kcal/hour, and the heating turbine units accounted for 35% of the total capacity of the turbine units.
