35T/H Steam coal fired Boiler

This kind of boiler is horizontal, 2 steam-drum, natural circling water tube boiler with a chain-grated stoker. The SHL 35t/h Boiler has 2 series, one is the saturated steam boiler, the other is the superheated steam boiler. The saturated steam boiler could supply the industrial steam to the industrial enterprise and also the domestic steam to the living area. The superheated steam boiler could provide the steam to the 5 MW turbine generator.

The designed boiler-using coal type is II level bitumite. The 7.9 meter chain-grate stoker is installed regarding such coal type. The front arch and the back arch are covered with fire-resistant material in order to lessen the surface caloric receptivity and form the high temperature zone, which could help the coal of relatively bad quality fire up and get forced combustion. Air comes from both sides of the stoker in order to guarantee the coal layer could receive even ventilation. The upper steam drum has air-water separator, overflow groove, and continuous sewer in order to guarantee the good steam quality.

The superheater is vertical. The economizer is the type of steel pipe, and there is one recirculation system to protect the economizer. 2 group of preheaters are below 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 the protection board.

This kind of boiler could supply good burning condition, which could make the coal easily fired. Together with the good dust remover, the boiler could reach good flue gas prevention and dust control result. Moreover, it is easy to operate, of reach overloading space, and of low labour intensity.

Remarks:
1. The parameter in the upper sheet is only for your reference, we will not inform customer the varied size and dimension due to the design and installation;
2. The coal consumption is calculated according to the coal in bulk heat rate 6000 kcal/kg;
3. The boiler exterior size is in accordance with the design drawing.
