关于常压锅炉供暖的思考

常压热水锅炉应用在建筑采暖中，具有免检，投资少、占地面积小的特点。但也存在一些致命的缺点。通过对这些状况的分析，认为以常压锅炉为热源的供暖系统，不宜设在层数高、作用半径大的供暖系统中，对小型的系统也应采取一些降低能耗，防止系统倒空的措施。

Heating problems of normal pressure boiler

Normal pressure hot water boiler is widely applied in building heating because of small investment and floor area of it. But it has some fatal disadvantages such as waste electricity, accruing empty in heating system, air accumulation of system and so on. Through analysis on those present situations author think that normal pressure boiler is properly adopted in the heating supply system with large story and large action radius.
