不少快装锅炉的进水管的位置布置不合理,如图所示。进水管从锅筒右侧进入锅内,90°拐弯后直指后封头,因而大量冷水从进水管管端出口直射锅炉后封头,使后封头经常聚积厚厚的泥迹和水渣。当锅筒内的第一对流管束靠近锅筒的右侧时,炉膛中产生的大量高温烟气必然从右侧短路进入第一 Many quick-installed boiler inlet pipe layout is not reasonable, as shown. Into the water pipe from the right side of the pot into the pot, 90 ° turn straight after pointing head, so a lot of cold water from the inlet end of the pipe directly to the boiler after the head, the head often gather thick mud and slag . When the first convection tube bundle in the drum is close to the right side of the drum, a large amount of high-temperature smoke generated in the furnace inevitably short-circuits from the right into the first
