35T/H-130T/H SHL series steam boilers

35T/H-130T/H SHL series steam boilers Introduction

This boiler is horizontal boiler with two steam drums, natural circulating water tube boiler. The SHL 35t/h boiler has two series, saturated steam boilers, and superheated steam boilers. The saturated steam boilers could supply steam to the industrial enterprises and living area.

Its designed fuel application is coal II bituminous. 7.9 meter length chain grate is special designed for this boiler Its front arch and back arch are covered with refractory materials in order to reduce arch 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 blow down to guarantee the good steam quality.
The super heater is vertical. The economizer is the type of steel pipe ,and there is one recirculation system to protect the economizer. Two sets of preheaters are assembled under the back flue duct. Air flow way is from downward to the upward.
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 collector, the emission of the boiler can totally meet the environment protection. Moreover, it is easy to operate, of reach overloading space, and of low labor intensity.

Application fileds

Our oil/gas fired boilers can be divided into DHS series angle tube boiler,SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above. The fire tube boilers, on the contrary, are intended for use at pressures below 2.5 MPa. Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible.
The three series are designed with large furnaces, the thermal efficiency is over 98%, and the NOx emissions are as low as 30mg/Nm3. The front and rear smoke boxes are all equipped with a unique sealing structure to ensure that the smoke box does not leak smoke. At the same time, it has the characteristics of fully automatic and safe operation.
