低压蒸汽锅炉在运行中,随着炉水不断蒸发、浓缩,杂质含量会逐渐增加。这些盐类,沉积物和泥污,如不及时清除炉外,随着炉水循环,形成二次水垢,导致水垢迅速增加,影响蒸汽品质,腐蚀金属。为了保持炉水中盐类、杂质的浓度在允许范围之内,就要排污,因此,锅炉的排污,是水处理中的重要工作,
Low-pressure steam boiler in operation, with the boiler water evaporation, concentration, impurity content will gradually increase. These salts, sediments and mud pollution, if not promptly remove the furnace, with the furnace water cycle, the formation of secondary scale, resulting in the rapid increase of scale, affecting the steam quality, corrosion of metals. In order to maintain the salt water in the furnace, the concentration of impurities within the allowable range, it is necessary to sewage, therefore, boiler sewage, water treatment is an important work,
