热水采暖系统,采暖质量高、舒适、投资小、管理容易、运行安全可靠,而且由于蓄热量大、输送热损失小、耗能比蒸汽采暖系统节省30%.因此,国发(7982)节能4号文规定,新建采暖系统一律采用热水采暖。鉴于我国工业锅炉制造厂能提供的热水锅炉,性能和数量均不能满足需要,用户往往不得不将现有的蒸汽快装锅炉改为热水锅炉使用。我局现有90%的采暖锅炉,就都是 Hot water heating system, high heating quality, comfortable, small investment, easy management, safe and reliable operation, but also because of heat storage, transmission heat loss, energy consumption than the steam heating system saves 30% Document No. 4, the new heating system should be hot water heating. In view of China’s industrial boiler manufacturers can provide hot water boiler, the performance and quantity can not meet the needs, users often have to be the existing steam boilers to hot water boiler to use. Our existing 90% of the heating boiler, it is all
