1 前言近些年来,低压锅炉的使用数量大幅度增多,其中蒸发量10t/h以下的占绝大多数,这些小容量锅炉随着锅炉用水软化处理工作的不断加强和提高,锅炉给水质量得到保证,锅内不结水垢,金属就裸露在水溶液中,一旦水中含有溶解氧,锅炉金属就会产生氧腐蚀。例如:贵阳市某医院的DZL4—13型锅炉安装投用仅一年多就因氧腐蚀被迫停炉检修;贵阳某厂的WWL4
1 Introduction In recent years, the use of low-pressure boilers has increased significantly, of which the evaporation of 10t / h or less accounted for the vast majority of these small-capacity boilers with water softening treatment continue to strengthen and improve the boiler feed water quality is guaranteed , The pot does not scale, the metal is exposed in aqueous solution, once the water contains dissolved oxygen, the boiler metal will produce oxygen corrosion. For example: Guiyang City, a hospital DZL4-13 type boiler installation put into use only due to oxygen corrosion was forced to shut down furnace maintenance; Guiyang WWL4 factory
