Lime kiln waste heat boiler

Lime kiln waste heat boiler

The lime kiln tail gas waste heat device includes a tail gas waste heat steam generation device and a tail gas waste heat heating air and gas device. The main function is to reduce the temperature of flue gas emissions, ensure the safe operation of bag filters, reduce the dust content of flue gas, ensure the normal operation of induced draft fans, increase the output of lime kilns, and generate saturated steam for production or grid connection.

The waste heat boiler system of lime kilns is mainly used for shaft kilns or rotary kilns in steel enterprises, as well as exhaust gas waste heat recovery equipment. It includes a waste heat boiler body with 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, including a steam superheater, evaporator, and economizer. The top of the waste heat boiler body is equipped with a drum; The inlet of the waste heat boiler body is equipped with an inlet guide device, while the bottom of the waste heat boiler body is equipped with an ash discharge device; The heating surface of the waste heat boiler body is a spiral finned tube, which includes a base tube and a finned equipment fixed on the periphery of the base tube according to a spiral line, occupying a small area and effectively saving equipment investment and civil engineering investment costs; The heating surface of the waste heat boiler adopts spiral finned tubes to enhance heat transfer, with high thermal efficiency and good sealing performance.
