Water Tube Boiler Coal Biomass
Yuanda Boiler supplies a wide range of solid fuel boilers for different industrial applications.



SZL SZW Water Tube Biomass Boiler
Yuanda SZL/SZW Series water tube boiler, adopt a double-drum offset furnace structure (D-type or A-type) and are available with chain grate or reciprocating grate stokers, delivering high efficiency, reliable operation, and eco-friendly, energy-saving performance.
Typecial fuel: biomass, coal, wood, rice husk, bagasse, palm kernel shell palm fibre, agro waste.


Technical Features SZL Boiler
Intelligent Combustion Control System
1. Multi-zone air distribution: Air is supplied in sections along the grate length, with independent airflow control for each zone.
2. Real-time oxygen monitoring: Combustion air is automatically adjusted based on flue gas oxygen content to maintain optimal combustion.
3. Layered temperature control: Different grate zones are temperature-controlled to prevent local overheating and slagging.
Anti-Slagging Design
1. Optimized front and rear arches: Enhance heat radiation and gas mixing for stable ignition.
2. Special grate bars: High-temperature and oxidation resistant, with clinker-breaking structure.
3. Multi-stage ash cleaning: Combination of mechanical cleaning and soot blowers keeps heating surfaces clean.
Environmentally Compliant Emissions
1. Low-NOx combustion: Air staging and flue gas recirculation reduce NOx formation.
2. High-efficiency dust removal: Multi-cyclone or bag filter options meet strict emission standards.
3. Fly ash reuse: Collected ash can be reused as potassium fertilizer raw material, supporting resource recycling.
