    碱煮除垢法:碱煮除垢法除垢,其效果要比酸洗除垢法差,但是碱煮后由于水垢松,因此对于难以用盐酸清除的水垢,在酸洗前也可以用碱煮法进行一次予处理。碱煮法操作简单,副作用也比较小。缺点是煮炉时间比较长,药剂消耗量比较多,且效果差。
    Alkali cooking descaling method: soda boiling descaling descaling method, the effect is better than acid descaling method is poor, but because of the scale after alkali cooking, so for difficult to use hydrochloric acid to remove scale, also can use in front of the pickling alkali boiling method to deal with at a time. Alkali cooking method, the operation is simple, there is less side effects. Defect is boiling out time is longer, reagent consumption, and the effect is poor. 
    机械除垢法:当铸铁热水锅炉炉内有疏松的水垢和水渣时,停炉后使铸铁热水锅炉冷却、放掉炉水,用清水冲洗后,即可用扁铲、钢丝刷和机动铣管器进行除垢。这种方法比较简单,多用于结垢简单的小型铸铁热水锅炉上。但劳动强度大,除垢效果差,容易损坏锅炉本体。
    Mechanical descaling method: when the hot water boiler furnace cast iron with loose scale and water slag, boiler stop after make the iron hot water boiler furnace cooling, put water, wash with water, can be used, with flat steel wire brush and mechanical milling pig for descaling. This method is simpler, more for small scale simple cast iron on the hot water boiler. But the intensity of labor is big, poor descaling effect, easy to damage the boiler body. 
    酸洗除垢法:酸洗除垢法大部分是采用盐酸或硝酸来清洗的。酸洗液是由盐酸加缓蚀剂或硝酸加缓蚀剂组成的。这种酸洗液既能消除锅炉中的水垢(除硝酸盐水垢时,需添加氢氟酸),又极少腐蚀铸铁热水锅炉。酸洗除垢有溶解作用、剥离作用和疏松作用。
    Pickling descaling method: acid descaling method mostly using hydrochloric acid or nitric acid to wash. Acid lotion is composed of plus inhibitor or nitric acid and hydrochloric acid corrosion inhibitor. The acid in the lotion can both eliminate boiler scale (except for the nitrate scale, the need to add the hydrofluoric acid), and little corrosion cast iron hot water boiler. Pickling descaling has dissolved, and the roles of exfoliation and osteoporosis.
