电站锅炉在运行过程中,受热面管子内壁上总是会不可避免的产生结垢或腐蚀产物的沉积,这种结垢的存在将直接影响锅炉的传热效率和金属壁温,长时间的结垢不仅能导致垢下介质浓缩腐蚀,甚至导致管子超温爆管,影响锅炉的安全和经济运行。为了避免因结垢给锅炉安全经济运行带来的负面影响,保证受热面管子正常工作,则需要做好化学监督工作,并定期对锅炉受热面内壁进行清
During operation of power plant boilers, the deposition of scale or corrosion products will inevitably occur on the inner wall of the heated surface pipe. The existence of such scaling will directly affect the heat transfer efficiency of the boiler and the metal wall temperature, and the long-time junction Scale can not only lead to the concentration of corrosion under the scale of media, and even lead to pipe burst over temperature, affecting the safety and economic operation of the boiler. In order to avoid the negative impact brought by the fouling on the safe and economical operation of the boiler and ensure the normal operation of the heating surface pipe, it is necessary to do chemical supervision and regularly clean the inner wall of the heating surface of the boiler
