Introduction

Yuanda Boiler, specialized in industrial boiler since 1956. We aim to offer the biomass boilers best suited for industrial heating, based on fuel and customer needs.

We have water tube biomass boiler, fire tube biomass boiler and water-fire mixed tube biomass boiler. Combustion equipment is rationally configured according to fuel characteristics such traveling grate, fixed grate, chain grate, reciprocating grate and fluidized bed, bubbling bed etc.

Can efficiently burn biomass/wood pellets, logs, bark, wood chips; agricultural by-products/waste—such as rice husks, palm shells, palm fibers, or bagasse; Mixed fuel like wood scraps, sawdust, and bulk fuel with high moisture content (up to 55%).

DZH DZL series Water-fire Tube Boiler

2. Automatic feeding, hand feeding for choose.
3. Radiation zone design with water-tubes in the side walls.
4. Convection zone with two tube wings and spiral smoke tubes in the steam drum.
5. Symmetrical distribution of the upper drum, water walls, and headers, ensuring thermal stability.
6. High efficiency (up to 85%) and optimized heating surface layout.
7. Packaged delivery, short installation.

SZL ZSW series Water-tube Boiler

1. Horizontal double-drum water-tube boiler.
2. Lightweight furnace wall, membrane wall design, patented A or D type design.
3. Efficiently burns high-moisture (up to 50%), high-ash biomass fuels and mixed bulk fuels.
4. Configured with different combustion equipment and materials according to different fuels (chain grate, moving grate, reciprocating grate, bubbling grate and so on).
5. Compact structure, high steam quality, continuous and stable heating.

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
