    环保采暖锅炉之管式热水锅炉有管架式和蛇管式两种,前者较为常见。管式热水锅炉是借助循环泵的压头使锅水强迫流动,并将锅水直接加热。这种锅炉大都由直径较小的筒体(集箱)与管子组成,结构紧凑,体积小,节省钢材,加工简便,造价较低。但是这种锅炉水容量小,在运行中如遇突然停电,锅水容易汽化,并可能产生水击现象。 

    Environmental protection heating boiler tube hot water boiler tube type and tube type two kinds, the former is more common. Tube hot water boiler is the head of circulating pump so that the pot of water flow, and water direct heating pot. This boiler is mostly by a smaller diameter tube (box) and a pipe, compact structure, small volume, steel saving, simple processing, low cost. But the water capacity of the boiler in the operation of small, in case of a sudden power failure, the pot of water easily vaporized, and may produce the phenomenon of water hammer.

    锅筒式热水锅炉早期大都是由蒸汽锅炉改装而成的,其锅水在锅炉内属自然循环。为保证锅炉水循环安全可靠,要求锅炉要有一定高度,因此这类锅炉体积较大,钢耗和造价相对提高。但是由于这类锅炉出水容量大且能维持自然循环,当系统循环泵突然停止运行时,可以有效地防止锅水汽化。也正是这个原因,近年来自然循环热水锅炉在我国发展较快。

    Drum type boiler early is mostly composed of steam boilers converted, the pot of water is a natural circulation in the boiler. In order to ensure the safe and reliable water circulation in the boiler, boiler to have a certain height, so this type of boiler is larger, steel consumption and cost increase. But because this kind of boiler water capacity is large and can maintain the natural cycle, when the system circulating pump suddenly stops running, can effectively prevent water evaporation. It is also for this reason, in recent years the natural circulation hot water boiler in china.

    环保采暖锅炉常用材料主要分为两大类,即锅炉用金属材料和非金属材料。金属用材料包含锅炉钢板、锅炉用钢管、锅炉构架用钢的各类型钢、结构钢板、锅炉用吊架用钢、支架用的耐热、低压锅炉用的各种铸件如灰铸铁、球墨铸铁、耐热铸铁、可锻铸铁、中低压锅炉燃烧设备各种炉排用铸铁件以及焊接材料等。另一类为非金属材料包含锅炉受压的人孔、头孔、手孔等用的各类密封面垫片、耐火砖。耐火浇注料、各类保温材料等。
