众所周知手烧炉的容量不能太大;链条炉耗钢多,加工量大;沸腾炉除尘负担重,耗电多,磨损重。往复炉排是一种耗钢量较少、制造加工容易,除尘效果稍好的机械化炉子,近几年燃用无烟煤的成功,更引起人们的重视。一、无烟煤的一般特性无烟煤的特性是挥发物含量仅为3～4%,质硬、密度大,主要成分是固定碳,内孔隙 As we all know, hand furnace capacity can not be too large; chain furnace consumption of steel, large processing capacity; boiling furnace dust burden, power consumption, heavy wear and tear. Reciprocating grate is a mechanized furnace with less consumption of steel, easy manufacture and processing, and slightly better dust removal effect. In recent years, the success of burning anthracite has drawn more attention. First, the general characteristics of anthracite anthracite is the volatile content of only 3 to 4%, hard quality, density, the main component is fixed carbon, the internal porosity
