Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a boiler smoke box. Background Art

[0002] The boiler smoke box refers to the space where the flue gas generated by the combustion chamber flows through, with the main purpose of heating and recovering the heat of the exhaust gas. It generally includes the flue gas duct, flue gas duct, flue gas treatment equipment and other parts. In hot water boilers, steam boilers and industrial furnaces, boiler smoke boxes are indispensable and important equipment. When the high-temperature flue gas flows in the furnace body, in order to increase the flow length on the heating surface, a front smoke box is required. However, when the flue gas flows in the front smoke box, if the temperature is too high, the front smoke box will be damaged.

[0003] In the prior art, smoke pipes in the front smoke box of the boiler are mainly straight pipes, and are mostly blocked by biomass, coal ash, coking coal and other materials. When cleaning the smoke pipes, they need to be disassembled one by one or cleaned individually with a brush. The number of smoke pipes is generally large, and during the use of the front smoke box, the overall temperature of the smoke pipes and the front smoke box is relatively high. In the subsequent cleaning process, burns are easily caused. Therefore, we propose a boiler smoke box to solve the above problems. Utility Model Content
