    清除锅炉受热面水垢的方法,主要有机械除垢和化学除垢两种。机械除垢是由人直接进行锅炉内,用扁铲或洗管器清除锅炉受热面水垢。化学除垢常用的是碱煮法和缓蚀盐酸清洗两种,具体按《锅炉化学清洗规则》规定和要求进行。
    Removal of boiler heating surface scale method, basically has two kinds of chemical and mechanical descaling descaling. Mechanical descaling is carried out directly by the people, in the boiler with flat or pipe cleaner to remove boiler heating surface scale. Chemical descaling gentle erosion hydrochloric acid cleaning is soda boiling method two kinds, specific according to the regulations and requirements of the boiler chemical cleaning rules.
    燃烧室的结焦大都产生在较大容量的水管锅炉上。由于炉膛温度高,煤的灰分熔点低,在炉墙上或受热面上结成硬焦。结焦严重时,不仅影响传热,还破坏水循环,威胁锅炉的安全。
    Combustion chamber coking are mostly produced in large capacity water tube boiler. Due to the high temperature in the furnace, low ash fusion point of coal, on the furnace wall or surface forming hard coke. Coked serious when, not only affect the heat transfer, but also destroy the water cycle, threatening the safety of the boiler.
    在清扫时,应注意检查受压元件表面有无腐蚀、鼓包、变形、渗漏、裂纹等情况。受热面有渗漏现象时,在渗漏处一般有白色结晶物,味咸苦。这是锅炉水蒸发后的残留盐垢。受热面有磨损时,表面一般露出金属光泽。

    When cleaning, should pay attention to check whether there is any corrosion, beat on pressure parts surface, deformation, seepage, crack, and so on and so forth. When the heating surface have leakage phenomenon, in the leaks generally have white crystal, salty taste bitter. Is this the boiler water evaporation residue salt deposit. The surface of the wear and tear, heating surface of general show metallic luster.
