Introduction:The horizontal combustion biomass heat-conducting oil furnace can obtain higher working temperature under lower operating pressure, and has the technical characteristics of low pressure and high temperature.


  YLW series boiler is a square coil horizontal chain grate assembly boiler, chain grate and boiler body separate from the factory, after the site is in place, just put the oil, electricity can be put into operation, the furnace using chain grate Mechanical coal, equipped with drums, induced draft fan for mechanical ventilation, and equipped with slag machine to achieve mechanical slag.

  During the operation, the fuel falls from the coal hopper to the grate for combustion. The high-temperature flue gas passes through the rear arch and enters the furnace in front of the furnace. After radiative heat exchange on the radiant heating surface, it enters the convection heating surface for convection heat transfer, and then leads to waste heat. The boiler enters the air preheater and enters the precipitator. After the dust is removed, the exhaust gas is drawn by the induced draft fan through the chimney to the atmosphere.

  The boiler heating surface consists of four parts: the radiant heating surface of the furnace, the convection tube bundle heating surface, the waste heat boiler, and the air preheater (economizer).


  • With low pressure and high temperature characteristics.
  • Stable heating, precise control of temperature.
  • Keep thermal efficiency at an optimal level.
  • Complete operation control and safety monitoring device.
  • Reduce other consumption, save electricity, water and oil
  • The fully digital portal milling machine ensures that the tube holes of the same type of tube sheet are strictly the same, eliminating individual deviations caused by manual scoring. It also overcomes the deviation of the roundness of the hole diameter caused by the different rigidity of the radial drilling machine.
  • Establish a stop point for process inspections and strictly ensure the execution of the first expansion and subsequent welding processes.
  • All smoke pipes and convection pipes are automatically welded.
  • The cylinder body is equipped with a reversing device to ensure that the weld seam is in the best welding position.
  • Tube blanking, discarding the wheel cutting, all using machine tool cold processing to ensure the processing accuracy and avoid over-burning.
