蒸汽锅炉的排污是锅炉运行中不可缺少的重要环节。就低压锅炉而言,目的在于:1、排除炉水中析出沉淀物(俗称水渣),避免锅炉结二次水垢;2,降低炉水溶解固形物含量,避免炉水溶解固形物含量达到临界值而引起汽水共腾,恶化蒸汽品质;3、使炉水维持适当的总碱度和PH值,以利锅炉防垢与防腐。为了达到这些目的,不仅要坚持定期排污,而且要定量排污。确定锅炉排污的依据应该是《锅炉水
Steam boiler blowdown is an indispensable part of boiler operation. For low-pressure boilers, the purpose is to: 1, remove precipitated sediments (commonly known as water slag), to avoid secondary scaling boiler; 2, reduce the dissolved solids content of furnace water to prevent the dissolved solids content of furnace water to reach the critical value Which leads to a total of Tengteng, deterioration of steam quality; 3, the furnace water to maintain the appropriate total alkalinity and PH value, to facilitate boiler scale and corrosion. In order to achieve these goals, we should not only insist on regular sewage discharge but also quantitative sewage discharge. The basis for determining boiler blowdown should be "boiler water
