No matter what kind of boiler, after a long time of use, many chemical reactions will occur in the boiler, and according to the different water quality used in the boiler, the chemical reactions in the boiler are also different, and many chemical substances will simply occur in the environment of high temperature and high humidity for a long time.

這就要求咱們往常在運用進程中，以及經過長時刻停用時，需求十分留心鍋爐爐體表裏的防腐保養。鍋爐的保養特別是鍋爐停爐之後的保養，應當留心的是，首要在鍋爐停爐冷卻後有必要要徹 底鏟除受熱麵的積灰和爐排上部以及爐體下部的灰渣，這樣能堅持煙道有必定的天然通風。

This requires us to pay great attention to the anti-corrosion maintenance in the boiler surface during the operation process and after long-term shutdown. For the maintenance of the boiler, especially after the boiler is shut down, it should be noted that after the boiler is shut down and cooled, it is necessary to completely remove the ash on the heating surface and the ash on the upper part of the grate and the lower part of the furnace body, so as to ensure that the flue has certain natural ventilation.

一般情況下為了防止爐體受潮應在爐膛和煙道中放置單調劑。如以生石灰作為單調劑則每立方米爐膛或煙道內一般應放置3kg左右。放置後應該緊密封閉一切的通風門。生石灰變粉後要替換如鍋爐房方位低窪，停爐期間地上泛潮嚴峻的時分應該選用常常小火烘烤和放置單調劑相結合的辦法。

In general, in order to prevent the furnace body from moisture, a single agent shall be placed in the furnace and flue. If quicklime is used as monotonic agent, about 3kg shall be placed in the furnace or flue per cubic meter. All ventilation doors shall be tightly closed after placement. The quicklime shall be replaced after it is powdered. For example, the boiler room is low-lying, and when the flooding on the ground is severe during boiler shutdown, the method of often baking with low fire and placing monotonic agent shall be selected.
