Biomass-fired Horizontal Type Steam Boiler Advantages

• Customized feeding system
  Different feeding systems are designed according to the characteristics of biomass fuels, effectively improving the overall efficiency of the boiler.
• Taller furnace
  Compared to a double-drum boiler, the length and width of a three-drum boiler remain unchanged, while the furnace height increases by 1 to 3 meters to meet the combustion requirements of non-molded biomass fuels.
• Inspection platform
  The inspection platform uses grid plates to ensure the strength and rigidity of the platform ladders;
  The reasonable layout ensures easy access to every operation and maintenance point.
• High thermal efficiency
  The dead angles of the heating surface that are swept by the flue gas are small, which makes it difficult to form eddies, resulting in high heat transfer efficiency of the heating surface area and an increased boiler thermal efficiency.
• Scientific and reasonable configuration of the grate
  According to different types of biomass fuels, users can be provided with either a chain grate or a reciprocating grate to meet their various needs;
  The use of suitable high-temperature-resistant grate pieces adapted to the combustion characteristics of biomass fuels improves the reliability of the grate.
• Ash blowing device
  An ash blowing device is arranged at the rear of the convection heating surface, and ash blowing pipe holes are reserved in the front of the furnace. Different ash blowing methods can be selected according to different fuels, and ash can be cleaned without stopping the boiler.
• Convective heating
  The advanced layout structure of the convection heating surface is adopted to make the dust generated by combustion easy to settle and discharge in the ash hopper, which not only reduces the burden on the dust collector but also is more environmentally friendly under the same conditions. And ensure that the heating surface has a high heat transfer effect during the operation of the boiler;
  Reasonably arrange the dust removal door to facilitate the thorough cleaning and maintenance of the convection heating surface in the later stage.
• Combustion chamber and burnout cooling chamber
  The boiler body and partition walls are surrounded by membrane water walls with a fully sealed structure;
  The furnace structure is front and rear arch-covered, and the lower front arch of the furnace front wall is an ignition arch, while the rear arch is a combustion-supporting arch.
• Independent air chamber
  Different numbers of independent air chambers are set from front to back of the grate according to different boiler capacity;
  Users can distribute air to different chambers according to different combustion conditions to ensure the sufficient combustion of fuel.
