苏联的城市集中供热采用了热电联合生产方式,从而大大节约了燃料,提高了燃料利用效率(达2～3倍),减少了大气污染,改善了燃料的供应、储存和燃烧过程,大大提高了劳动生产率。从城市建设和管理的角度来看,还完全省去了燃料储存场占地和附属于单个建筑物的锅炉房所占用的建筑面积。城市热化是节约燃料最好的途径。但只有当热化的三个环节(热电中心、热网和用户)相互配套时,集中供热的效益才能充分地发 The Soviet Union’s urban district heating uses a combined heat and power production method, which greatly saves fuel, improves fuel utilization efficiency (up to 2 to 3 times), reduces air pollution, and improves fuel supply, storage, and combustion processes. Labor productivity. From the point of view of urban construction and management, the floor space occupied by fuel storage sites and boiler rooms attached to individual buildings has also been completely omitted. Urban heating is the best way to save fuel. But only when the three stages of heating (thermoelectric center, heating network, and user) are matched with each other, the benefits of centralized heating can be fully developed.
