[0002] A waste heat boiler is a special type of boiler. Its main feature is that it utilizes the waste heat in waste gas, waste materials or waste liquid in industrial processes, as well as the heat generated by the combustion of combustible materials to heat water and generate steam or hot water.

[0003] Most of the existing waste heat boilers do not have a descaling function. Since the flue gas often carries a large amount of smoke impurities, the smoke impurities are easily attached to the inner wall of the boiler during long-term use, resulting in a significant reduction in the heat exchange efficiency of the inner wall of the waste heat boiler, thereby causing the operating efficiency of the waste heat boiler to decline and affecting the waste heat utilization rate of the waste heat boiler. Therefore, staff are required to regularly disassemble the furnace body to clean the impurities on the inner wall. The cleaning is very troublesome and time-consuming, and the cleaning efficiency is low. In addition, the operation of the waste heat boiler needs to be suspended during the cleaning process, which is easy to affect the working efficiency of the waste heat boiler.

[0004] To this end, we proposed a waste heat boiler with descaling function. Utility Model Content
