常压燃气锅炉供暖系统设计中应注意的几个问题

The Problems Worth Being Paid Attention to in Designing Atmospheric Gas-Burning Boiler Heating Systems

随着城市燃气事业的发展和环保意识的增强 ,小型燃煤锅炉的应用越来越受到限制 ,甚至被禁用。常压热水锅炉 (以下简称常压锅炉 )以其结构简单、耗钢量少、体积小、占地面积小、运行安全可靠、燃料供应方便及不需储存等特点 ,越来越广泛地在中小型建筑供暖工程中被采用。

With the development of city gas undertaking and the increase of the awareness of environmental protection,the application of the small_size coal_burning boiler has been limited more and more,and has even been banned.The atmospheric hotwater boiler('Atmospheric Boiler'as its abbreviation in the following part)has been adopted more and more widely in the heating engineering of small_middle_size buildings,because of its simple structure,less consumption of steel,small volume,less occupying of ground area,safe and reliable working,convenient supply of fuel and needless storage of fuel.The present paper proposes some problems that should be paid attention to in designing atmospheric boiler heating systems and the application of on_off combination valve.
