　　After the boiler is used for a long time, scale and rust problems will inevitably occur. The occurrence of these problems, due to the generation of fouling, reduces the heat transfer performance, resulting in a reduction in the effectiveness of the boiler. Therefore, it is difficult to achieve the rated evaporation; and due to poor heat transfer, the metal temperature will be too high, and under the action of boiler pressure, the furnace tube will bulge or even explode; poor heat transfer will also make fuel Increased consumption, increased operating costs, and shortened boiler life. Therefore, after the boiler is fouled, it is necessary to take necessary measures to remove the scale.
