国家标准局及劳动人事部颁布了GB1576-85《低压锅炉水质标准》一文,对锅炉额定蒸发量大于2T/h的均要进行除氧。锅炉给水虽经软化或除盐等方法处理以使锅炉受热面不结水垢,但水中仍含有氧和其他气体,它的存在将促使锅炉设备及热力系统的金属表面产生酸性腐蚀。这种腐蚀通常是局
The National Bureau of Standards and the Ministry of Labor and Personnel promulgated the article GB1576-85 “Quality Standards for Low-Pressure Boilers”, and all oxygen removal is required for boilers with a rated evaporation greater than 2T/h. Although the boiler feed water is softened or desalinated and other methods are used to make the heating surface of the boiler not scale, but the water still contains oxygen and other gases, its presence will cause acid corrosion on the metal surfaces of boiler equipment and thermal systems. This corrosion is usually a bureau
