补充资料:动力机械: 省煤器
布置在锅炉尾部烟道内加热给水的部件。它的作用是吸收锅炉尾部烟气中的部分热量﹐降低排烟温度﹐以节省燃料。现代锅炉一般都有省煤器。省煤器一词来源于燃煤锅炉﹐对于燃油﹑气和其它燃料的锅炉习惯上也称为省煤器。省煤器按出口水是否汽化分为沸腾式和非沸腾式。沸腾式的省煤器的沸腾率(出口水中汽化部分的质量百分数)不应超过20%﹐过大会增加流动阻力﹐甚至会出现管组中各管流量交替脉动﹐使省煤器振动﹐从而造成损坏。中压锅炉的省煤器常为沸腾式﹐其它压力的锅炉则常为非沸腾式。省煤器按结构和材料又可分为铸铁式和钢管式。铸铁式省煤器(见图 铸铁式省煤器 )强度不高﹐用于压力小于2.5兆帕的锅炉。为了加强传热﹐管外有大量鳍片。铸铁式省煤器承受振动和冲击的能力较差﹐故不能用作沸腾式﹔但耐腐蚀性能良好﹐可用于给水未经除氧的工业锅炉。钢管式省煤器不受压力限制﹐可以用作沸腾式﹐一般由外径为32~51毫米的碳素钢管制成。有时在管外加鳍片和肋片﹐以改善传热效果。钢管式省煤器由水平布置的并联弯头管子(习称蛇形管)组成。
