Technical Field

[0001] The utility model relates to the technical field of waste heat boilers for incinerators, in particular to the structure of a waste heat boiler for incinerators. Background Art

[0002] At present, incinerators are commonly used in the harmless treatment of medical and domestic waste and animals. The principle is to use the combustion of fuels such as coal, oil, and gas to burn and carbonize the objects to be treated at high temperatures to achieve the purpose of disinfection.

[0003] Among them, when the incinerator is in use, a large amount of high-temperature flue gas will be generated. In order to reduce energy loss in the market, the high-temperature flue gas will be collected and used with a heat exchanger to convert the high-temperature flue gas into usable waste heat to reduce energy loss.

[0004] When the heat exchanger is exchanging heat, a large amount of scale will form on the surface of the copper tube inside the heat exchanger as the water is continuously heated, which will reduce the efficiency of water heating over time. For this reason, we propose a structure of an incinerator waste heat boiler to solve the above problem. The scale on the surface of the copper tube inside the heat exchanger can be continuously cleaned to ensure the efficiency of waste heat recovery. Utility Model Content
