  • Previous:
  • Next:

  • 1.Energy saver, condenser and boiler structure can fully absorb the flue gas preheating and gasification latent heat,the thermal efficiency is 10% higher than the ordinary boiler.

    2.Adopt top level PLC automatic intelligent control cabinet and interlock protection program,which can effectively prevent water shortage, over pressure, over temperature, gas leakage, flame out and so on.

    3.Condenser adopts ND steel, which is characterized by its cost-effective,heat-resistant and corrosion-resistant performances.

    4.Condensing oil/gas fired boiler adopts horizontal flue gas three-pass integrated low resistance design with national invention patent technology, which facilitates a super high thermal efficiency, small floor area.

    5.Adopt corrugated furnace tank and threaded smoke pipe structure which not only increases the radiation and convection heat transfer area, but also satisfies the needs of the free expansion of high temperature radiation.
