Biomass Fired Boiler

chain grate boiler | water tube boiler | Membrane wall boiler

SZL series boiler is double drum boiler with seamless full membrane wall, grate combustion burning, can produce steam for industrial production. Also our company designing SZL-D type boiler most suitable for biomass fuel.

Output: saturated / superheated steam
Capacity: 2-40 ton/h
Styles: SZL-D, SZL-A
Available Fuel: coal, biomass, woodchips, palm shell/fiber, waste scrap, bagasse, sawdust, husks etcn
Applied Industries: steam for processing heating / drying / steam turbine etc


  • Yuanda SZ series coal biomass fired boiler is a water tube boiler, fuel burning on chain grate, reciprating grate or step grate. The maximum pressure of this boiler can reach 3.82 Mpa / 450℃, widely used for factory processing or drive steam turbine.

  • Design fuel: coal, biomass,palm oil shell,wood chips,biomass pellet,cashew nut, rice husk, solid fuel,etc. Yuanda Boiler good at biomass furnace design, different fuel has different furnace; Design pressure:0.4Mpa, 0.7mpa, 1.0Mpa, 1.25Mpa, 1.6Mpa,2.5Mpa, 3.0mpa, 3.82mpa; SUPERHEATED BOILER please tell us, it needed to specially design.

  • SZL coal /biomass boiler has A & D type, is our company patented feature product. This boiler has the characteristics of ①15% bigger furnace combustion, the heated area increases by 40% ②Light furnace wall, not easy to collapse, good airtightness, no deformation, no dust falling; ③The best adjustability, segmented air supply (preheating zone, drying zone, main combustion zone, coke zone, ash slag zone) can freely adjust the air volume ④ Secondary cyclone burnout chamber, greatly reduce fuel cost, improve boiler thermal efficiency ⑤ Built-in dust removal device in the furnace, effectively solve the problem of coking

Typical Project


Product Advantages

★ The double-drum vertical arrangement and upper and lower assembly save the floor area of the boiler room.

★ It adopts large grate area, improving fuel adaptability and combustion efficiency.

★ The boiler has high dedusting efficiency, built-in deashing, and low original dust discharge concentration;

★ It has complete control function, is safe and steady, and guarantees the operation more;

★ It adopts a close isobaric wind chamber with more uniform air distribution and smooth regulation;

★ Its arch is designed by adopting momentum method, and “α” flame has more sufficient combustion;

★ The new arch and insulating materials have little radiation loss and increased heat efficiency;

★ It is novel in appearance, beautiful and pragmatic.
