Product Details
Biomass Coal Steam Boiler
- Automatic Chain Grate Stoker: The advanced Chain Grate system ensures stable fuel feeding, uniform combustion, and automatic ash removal, minimizing manual labor and downtime.
- Superior Thermal Efficiency: Advanced membrane water wall design ensures a thermal efficiency of over 85%, significantly reducing your annual fuel costs.
- Fuel flexibility is at the core of this design. The automatic chain-grate stoker accepts a wide range of solid biomass fuels — wood pellets, wood chips, sawdust, rice husks, palm kernel shells (PKS), bagasse, coconut shells, and compressed biomass briquettes — giving you the freedom to switch fuels based on local availability and cost.
- Designed for 24/7 continuous operation in demanding environments: food & beverage processing, textile dyeing, paper mills, plywood & timber drying, sterilization, and district heating.
- Every unit is built to ASME / ISO / CE standards with full radiography inspection on all pressure welds.

Certified Quality You Can Trust
1. A-Grade Boiler Manufacturing License (China's highest tier)
2. ASME / ISO / CE certified
3. 107+ technical patents in combustion, heat transfer, and control systems
1. Multi-Fuel Biomass Combustion – One Boiler, Every Fuel
The chain grate design (DZL/SZL) accepts a wide range of biomass fuels without modification. Whether you have rice husk in Vietnam, bagasse in Thailand, palm kernel shell in Indonesia or wood pellets in Europe, our boiler burns it cleanly and efficiently. Ask us for a free fuel analysis to confirm the best combustion design for your local fuel.
2. Energy Saving Boiler Design – Lower Steam Cost
High thermal efficiency 99% comes from: large heating surface, optimized chain grate, three-pass flue gas flow, and optional economizer + air preheater to recover waste heat. The result is lower fuel consumption per ton of steam and a dramatically lower steam production cost versus oil or coal fired boilers.
3. Fully Automatic Operation – Less Labor, Fewer Errors
PLC-based automatic control with touch screen: automatic fuel feeding, auto ignition, auto water level, auto pressure control, auto alarm and safety shutdown. One operator can supervise multiple boilers. Remote monitoring and mobile alert are available on request.
Why Dabonn Biomass Boilers Deliver More Value | ||
Your Concern | Dabonn's Answer | |
Fuel cost is killing my margin | Our multi-fuel design burns biomass pellets, wood chips, palm shells, bagasse, rice husks — whatever is locally abundant and cheap | |
I worry about unstable steam output | Double-drum / water-fire tube hybrid design ensures steady pressure even under fluctuating load | |
Maintenance is a headache | Large furnace volume + optimized grate design = complete combustion, less ash, less cleaning | |
I need it to run 24/7 | Heavy-duty structure, thickened steel plates, and automatic slag removal for non-stop operation | |
Environmental compliance | Integrated dust removal + desulfurization options. Emissions meet EU / local standards | |
I don't have technical staff on site | Full PLC automation with remote monitoring support | |
