High efficiency and stable operation. Easy installation and low operating costs.
SZL SZW一 Biomass Boiler
Double-drum Boiler | Water-tube | Full membrane wall | Chain/reciprocating grate | 4 to 35 t/h.
Double-drum structure in a "D" or "A" configuration, with a fully sealed membrane wall design to enhance sealing and heat transfer. Designed for high thermal loads and continuous operation.
Advantages
1. Complete Combustion, No Slagging
The large furnace and high combustion chamber design extend the fuels' combustion time in the furnace. Additionally, the adoption of staged air distribution and staged combustion technology promotes thorough mixing of fuel and oxygen, enhancing fuel burnout rate. This design also effectively controls the combustion temperature to prevent slagging.
2. High Thermal Efficiency
The adoption of membrane water-cooled walls and water-cooled arch structures reduces air leakage rate and heat dissipation, extending the service life of the furnace arches.
3. No Back-Fire (No Hopper Burning)
Based on the characteristics of biomass fuels, appropriate feeding methods and arch design are implemented to prevent back-fire.
4. No Ash Accumulation, Easy Ash Discharge
The rationally configured soot blowing device enables online cleaning, preventing ash accumulation on heating surfaces.
5. Easy Maintenance
Equipped with well-planned ash cleaning doors and ash discharge doors, the boiler facilitates inspection and routine maintenance.
6. Customized Solutions Save Money And Time
Customized feeding system, combustion system, slag discharge system, water treatment system, flue gas treatment system and boiler room layout.
