Introduction

Yuanda Boiler, specialized in industrial boiler since 1956, is a leading supplier of biomass boiler, wood boiler. 

We hold international certifications including ASME, CE, ISO, DOSH, EAC, GOST, TUBE, and BUV, ensuring reliable quality and high safety. More than 10,000 projects have been completed worldwide.

We offer a variety of biomass boilers, including water-tube, fire-tube, and hybrid water-fire tube boilers, as well as double-drum, single-drum, D-type, and A-type boilers.

Customized combustion equipment (traveling grate, fixed grate, chain grate, reciprocating grate, water-cooled vibrating grate, fluidized bed, and bubbling bed), can efficiently burn biomass/wood pellets, wood chips, sawdust, logs, bark, jhute, rice husks, palm shells, palm fibers, bagasse, and mixed solid fuels, achieving economic and environmental benefits.

DZ series Water-fire Tube Biomass Boiler

DZL: Horizontal single-drum boiler with moving grate(traveling grate, reicprocating grate). Automatic fuel feeding, automatic slag removal, packaged design, short installation. Suitable for coal and biomass. Stable operation, high efficiency, good for medium to large factories.

DZH: Horizontal single-drum boiler with manual traveling grate or fixed grate. Manual feeding, manual slag removal, low cost. Simple structure, easy to operate. Good for coal, cutwood, firewood, jhute, cashew shell, and other big solid fuel.

SZ series Water-tube Biomass Boiler

SZL: Double-drum water tube boiler with chain grate. D-type and A type boiler availaible. Automatic feeding, high thermal efficiency, strong load adaptability, reliable steam output. Suitable for coal and dry biomass fuel.

SZW: Double-drum water tube boiler with reciprocating grate(bubbling grate, vibrating grate). Suitable for high-moisture biomass fuels like wood residue, chips, sawdust, bagasse, bark, palm fiber and EFB. Stable combustion, low emissions, good for biomass-rich industries.

Advantages

① Wide applicability for kinds of biomass fuel, pellet, and high-moisture, high-ash fuels (wood waste, sawdust, palm shells, fiber, rice husks, bagasse, etc.)

② No fuel size limit – supports flakes, blocks, chips, granules, powders

③ Three-step burning process (preheating + main combustion + burnout) with four stages: drying, pyrolysis, combustion, burnout – combustion efficiency ≥90%

④ Smart air control – multiple independent air chambers for precise airflow adjustment per combustion stage (preheating zone, drying zone, main combustion zone, coke zone, ash slag zone)

⑤ Active slag breaking and self-cleaning – reciprocating grate breaks slag and removes ash automatically

⑥ Water-tube boiler design – high-quality steam, high safety, high pressure capability, can produce superheated steam

⑦ Robust grate bars made of heat-resistant cast steel – long service life, easy maintenance

⑧ Wide load adjustment (30%-110%) with rapid response – adapts to production line fluctuations

⑨ Fully automatic control (PLC/DCS) – auto feeding, ignition, air-fuel ratio adjustment, ash removal, fault alarm and protection

⑩ Real-time fault monitoring – auto alarm and protection program activation upon abnormality

⑪ Modular design – pre-assembled boiler body, feeding system, dust removal system, control system, reducing on-site work

⑫ Convenient maintenance – multiple inspection doors and observation holes for maintenance without shutdown

⑬ Automated ash removal – soot blower effectively removes ash from heated surfaces

⑭ Equipped energy-saving device like economizer/preheater, and cyclon/bag filter/wet scrubber, environmental protection and energy conservation
