Have a Question?

Coal-fired boilers

Our coal-fired chain grate boilers and coal-fired fluidized bed boilers mainly produce hot water, saturated steam or superheated steam for industrial use. Coal-fired boilers have lower operating costs – nearly 50% lower than boilers using oil or natural gas. Coupled with our proven high-efficiency, low-emission clean coal technology, our coal-fired boilers have the advantages of sufficient output, high thermal efficiency and wide coal adaptability without compromising safety and reliability.

  • Safe water circulation
  • Anti-seismic Structure
  • CNC manufacturing technology
  • Advanced welding process
  • Precise parts processing
  • Unique structural design

Gas-fired(oil-fired) boilers

Our oil/gas fired boilers can be divided into 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.

  • Energy conservation
  • longer lifespan

Biomass-fired boilers

We cooperate with Shanghai Jiao Tong University to research, develop and manufacture biomass boilers that use wood chips, straws, palm shells, mesocarp fiber, empty fruit bunch (EFB) fiber, rice husk and other wastes as fuels in order to achieve zero carbon dioxide emissions. After numerous tests and simulations, we have developed a reasonable structure of furnace arch, furnace wall and furnace heating surface that guarantees combustion efficiency and evaporation rate. NOx emissions of our biomass boilers can be as low as 100 mg/Nm3 with thermal efficiencies up to 90%.
