Introduction
Yuanda Boiler, Over 70 years in boiler design, manufacturing, installation, and turn-key boiler system solutions.
As a leading manufacturer and supplier of coal/biomass/wood boiler, we provide complete boiler systems & auxiliaries for industrial heating & drying.
Our Main Product Include: Hand Feeding Boiler (DZH) Fire Tube Biomass Boiler (DZL DZW) Water Tube Biomass Boilers (SZL SZW DHL CFB) Vertical Boiler (LSG CWHS) Hybrid Biomass Boiler (WNS-T)
Selling Point: We custom the furnace chamber, feeding & combustion system to your fuel's specific type, size and moisture, to ensure stable steam supply, high efficiency and continuous operation.
Efficiently utilize local biomass fuels such as firewood, log, tree bark, biomass waste, wood chips, sawdust, jute, rice husks, palm shells, palm fibers, bagasse, and mixed solid fuels, which not only reduces fuel costs but also promotes the sustainable use of energy.
DZ series Biomass Boiler
DZL: Horizontal single-drum boiler with moving grate(traveling grate, reicprocating grate). Automatic fuel feeding, automatic slag removal, packaged design, short installation.
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 Biomass Boiler
Horizozntal double drum water tube boiler with chain grate(SZL) reciprocating grate(SZW) bubbling grate(SZF).
Automatic feeding, high thermal efficiency, strong load adaptability, reliable steam output. Suitable for kinds of biomass fuel, including high-moisture biomass, wood waste, bagasse, EFB etc.
High combustion chamber, staged air distribution, and staged combustion technology ensure complete fuel combustion while effectively preventing slacking. The membrane water wall and water cooled arch improve thermal efficiency and reduce heat loss. dot dot data and optimized feeding system prevents fuel back burning while the online soot blowing system keeps heating surfaces clean for long-term efficient operation.
Advantages
High Combustion Efficiency | No Slagging | High Thermal Efficiency | No Fuel Hopper Burning | Online Soot Blowing | Easy Maintenance | Short Installation | Low Emission
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. 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
