Waste heat boiler of lime kiln

The tail gas waste heat device of lime kiln includes tail gas waste heat steam generating device, tail gas waste heat heating air and gas device. The main functions are to reduce the flue gas emission temperature, ensure the safe operation of the bag filter, reduce the dust content of the flue gas, ensure the normal operation of the induced draft fan, increase the output of the lime kiln, and the saturated steam generated at the same time is used for production or grid connection.

The waste heat boiler system of the lime kiln is mainly used for the vertical kiln or rotary kiln of the iron and steel enterprise, and the waste heat recovery equipment of the tail exhaust gas, including the waste heat boiler body in a vertical or horizontal structure. The heating surface of the waste heat boiler body is arranged from top to bottom along the flow direction of the flue gas, and the steam superheater, evaporator and economizer are arranged from top to bottom. The top of the waste heat boiler body is installed with a drum; The inlet of the waste heat boiler body is installed with an inlet guide device, while the bottom of the waste heat boiler body is installed, and the waste heat boiler is installed with an ash discharge device; The heating surface of the waste heat boiler body is a spiral fin tube, which includes the base tube and the fin equipment fixed on the periphery of the base tube according to the spiral line, occupies a small area, which can effectively save equipment investment and civil engineering investment costs; Heat transfer surface of waste heat boiler adopts spiral fin tube to enhance heat transfer, with high heat efficiency and good sealing performance.
