热电结合为世界公认的有效节能措施,但热电结合能否达到最佳的节能效果这和所选机组的型式和热化系数的大小有关。本文对供暖机组的型式,运行方式和热化系数进行了讨论。对变化幅度大,温度水平低的采暖热负荷,大型低真空抽汽冷凝式汽轮机是区域集中供热的理想机组。这种机组具有热经济性高,运行灵活的优点。这种供热机组
The combination of thermoelectricity is recognized as a world-wide effective energy-saving measure, but whether the combination of thermoelectricity can achieve the best energy-saving effect depends on the type of the selected unit and the size of the heating coefficient. This article discusses the type of heating unit, operating mode and heating coefficient. Large changes in temperature, low temperature heating load, large low-vacuum extraction condensing steam turbine is the ideal unit for district heating. This unit has the advantages of high thermal economy and flexible operation. This type of heating unit
