Introduction
1. Our company adopts advanced unique technology from Denmark. It cuts electricity costs by around 70% compared with rival biomass pellet burners. With a flame velocity of 4 m/s and flame temperature of 950°C, it is suitable for boiler upgrading. This automatic biomass furnace features energy‑saving performance, eco‑friendly property, high thermal efficiency, simple installation, easy operation and long service life.
2. High‑efficiency combustion with fast ignition. Streamlined fire‑channel design eliminates ignition resistance. Adopting boiling semi‑gasification combustion and tangential swirling secondary air, its combustion efficiency exceeds 95%.
3. Intelligent control system with dual‑frequency automatic constant‑temperature control. It supports adjustable firing levels and overheating protection for reliable safety performance.
4. Slight positive‑pressure combustion prevents flashback and flame‑out to ensure stable operation.
5. Wide thermal‑load regulation range. The load can be adjusted rapidly within 30%‑120% of rated capacity for quick startup and sensitive response.
6. Broad fuel adaptability. It supports 6‑10 mm fuels including biomass pellets, rice husks, peanut shells, sawdust, wood shavings and agricultural waste.
7. Excellent environmental performance. Running on renewable biomass fuel, low‑temperature staged combustion reduces NOₓ, SOₓ and dust emissions to meet emission standards.
8. Automatic feeding and air‑powered ash removal. Simple maintenance, only one‑person attendance is required.
9. Significant cost advantages. Low modification cost for various boilers. Heating cost is far lower than electric, oil‑fired and gas‑fired heating systems.
10. Fitted with premium supporting accessories.
11. Elegant appearance with exquisite craftsmanship and metallic paint finish.

Working Schematic Diagram
1. SL2 Series biomass particles combustion hot blast furnace consists of biomass pellet burner, screw feeding system, combustion chamber, high-temperature axial fans, induced draft fan, smoke exhaust pipe and dust removal water tank.
2. The gasification chamber is the core component enduring continuous temperature around 1000°C. Imported special high-temperature resistant materials (max 1800°C) extend service life. Multiple protective designs keep the shell external temperature close to ambient temperature.
3. Triple air distribution structure maintains furnace pressure at 5000–7000Pa. Stable flame temperature can reach up to 1000°C to satisfy diverse industrial drying requirements.
4. Biomass fuel enters the combustion chamber for gasification combustion. High-temperature axial fans deliver hot air to drying equipment. Flue gas is purified by dust removal equipment before discharge.
