Introduction
Biomass fired boiler is a kind of thermal equipment that uses wood/biomass-based fuel to heat water inside boiler then produce steam or hot water for factory production line.
Yuanda Boiler's biomass boiler is a category of industrial boilers, not a specific type of boiler. We design and manufactur different biomass boiler based on fuel type, to meet various industrial heating and processing needs. It can minimize fuel costs and achieve high economic benefits.
These boiler features an upper furnace and a lower combustion chamber, modular design makes installation and maintenance easy. Could efficiently and environmentally burn firewood, tree bark, log, pellet, briquette, wood chips, sawdust, shavings, timber waste, coffee husks, waste fabric, olive pomace, rice husk, EFB&palm fiber, cashew nut shells, walnut shells, and bagasse.
"LSG series" Vertical Boiler
LSG vertical boiler also known as small wood biomass boiler. It is the vertical fixed grate boiler with water tube. It can burn firewood, log, coal, biomass, waste jute, charcoal, pellets.
Vertical design saves space, manual feeding, reduce mechanical failures, easy to install and operate.

SZL/SZW series boiler is horizontal double-drum, water tube structure assembled boiler.
Features:
1. Full membrane water-cooled wall structure, stable and efficient operation.
2. Custom-made according to fuel, configure different combustor (chain grate, moving grate, traveling grate, reciprocating grate, bubbling bed grate).
3. Three-stage combustion zone "preheating + main combustion + burn out".
4. Wide fuel adaptability, no size limited. Particularly suitable for mixed biomass fuels and high-moisture fuels, irregular bulk fuel.
5. Active slag removal and self ash cleaning, low ash accumulation.
6. With energy saving device and dust collector system, sufficient output, low emission.
7. Modular design makes installation and maintenance simple.

"DZL series" Biomass Boiler
DZL and DZH boilers, is horizontal water & fire tube packgaed steam boiler. It is also called: a revolution in industrial boilers.
Features:
1. The upper furnace and combustor are packaged before delivery, quick installation, less investment.
2. Manual type traveling grate available, support hand feeding to reduce cost.
3. Due to packaged design, max steam capacity up to 8 ton, heating power up to 5600kw.
4. Spirally corrugated fire tubes, improves thermal efficiency, reduces flue gas temperature.
5. Wing-shape flue, allows smoke to enter the front smoke box smoothly, prevents tube sheet damage.
6. "α"-shaped flue gas recirculation and secondary air distribution technology.
One-stop boiler solution: Supply complete system including feeding system, boiler body, combustion equipment, flue gas purification system, soft water treatment system, waste heat recovery system and PLC automatic control system.
High Fuel adaptability: Different fuel, different solution. Reduces fuel costs, and unaffected by fluctuations in a single fuel market.
High efficiency and reliability: Ensures continuous production and provides stable high-temperature, high-pressure steam.
Economical operation: Significantly saves investment and yields substantial long-term economic benefits.
Automation and intelligence: Reduces labor costs and operational complexity, and improves management efficiency.
Environmental compliance: Meets emission requirements and enhances the company's green image.
