SHL 35t/h Boiler

This kind of boiler is horizontal, 2 steam-drum, natural circling water tube boilerwith a chain-grated stoker. The SHL 35t/h Boiler has 2 series, one is the saturatedsteam boiler, the other is the superheated steam boiler. The saturated steamboiler could supply the industrial steam to the industrial enterprise and alsothe domestic steam to the living area. The superheated steam boiler could providethe steam to the 5 MW turbine generator. The designed boiler-using coal type is II level bitumite. The 7.9 meter chain-gratestoker is installed regarding such coal type. The front arch and the back archare covered with fire-resistant material in order to lessen the surface caloricreceptivity and form the high temperature zone, which could help the coal of relativelybad quality fire up and get forced combustion. Air comes from both sidesof the stoker in order to guarantee the coal layer could receive even ventilation.The upper steam drum has air-water separator ,overflow groove, and continuoussewer in order to guarantee the good steam quality.The super heater is vertical. The economizer is the type of steel pipe ,and thereis one recirculation system to protect the economizer. 2 groups of preheaters arebelow the back flue gas well. Air is from below to the above.The boiler wall is heavy-duty wall , the front wall and the head have installed theprotection board.This kind of boiler could supply good burning condition, which could make the coaleasily fired. Together with the good dust remover, the boiler could reach goodflue gas prevention and dust control result. Moreover, it is easy to operate, ofreach overloading space, and of low labor intensity.
