Water Tube Biomass Boiler
SZL/SZW series biomass fired steam boiler is a water tube steam boiler specially designed for industrial applications using renewable biomass fuels. It adopts a double-drum, water-tube structure with membrane water walls and a chain grate stoker/reciprocating grate stoker, providing reliable combustion, efficient heat transfer, and stable steam output.
Typecial fuel: biomass, coal, wood, rice husk, bagasse, palm kernel shell palm fibre, agro waste.

Advantages of SZL SZW Boiler
1. Water-Tube Design
Water-tube heating surfaces provide efficient heat transfer and fast steam generation, making the boiler suitable for continuous industrial operation.
2. Membrane Water-Wall Furnace
The membrane water-wall structure reduces heat loss, improves furnace tightness, and provides effective radiant heat absorption.
3. Reciprocating Grate Stoker
The reciprocating grate continuously moves and distributes biomass fuel, promoting stable combustion and better burnout.
4. Wide Fuel Adaptability
Suitable for various biomass fuels, including wood chips, rice husk, sawdust, bagasse, palm kernel shells, and other agricultural residues.
5. Stable Steam Output
The optimized furnace and heating surface arrangement ensures stable heat transfer and reliable steam production under continuous operation.
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.
Biomass Boiler Solutions
Yuanda provides customized biomass boiler system solutions based on your specific project requirements. Our technical team can design and optimize the complete boiler system, including boiler capacity, steam pressure, biomass fuel type, grate system, feeding system, dust removal, flue gas system, water treatment, control system, and other auxiliary equipment.
1. Biomass Fuel Feeding System
The biomass fuel feeding system is customized according to the fuel characteristics, particle size, moisture content, and boiler capacity. Depending on the application, the system may include fuel hoppers, belt conveyors, screw feeders, hydraulic pushers, rotary feeders, or other suitable feeding equipment to ensure stable and continuous fuel supply.
2. Combustion System
Different combustion technologies are available to match various biomass fuels and operating conditions, including **chain grate, travelling grate, reciprocating grate, bubbling fluidized bed (BFB), and circulating fluidized bed (CFB)**. The combustion system is selected based on key fuel properties such as particle size, moisture content, ash content, calorific value, and combustion characteristics, ensuring efficient and stable combustion.
3. Dust Removal & Flue Gas Treatment System
The flue gas treatment system is configured according to the fuel type, boiler capacity, and applicable emission requirements. Available equipment includes cyclone dust collectors, multi-tube cyclone dust collectors, bag filters, and other suitable emission-control equipment, providing effective removal of particulate matter and helping the boiler system meet required emission standards.
4. Feedwater & Water Treatment System
Proper boiler water treatment is essential for safe operation, energy efficiency, and long-term boiler service life. Depending on the project requirements, the water treatment and feedwater system may include a water softener, deaerator, feedwater tank, feedwater pump, chemical dosing system, and other auxiliary equipment to maintain appropriate feedwater quality and protect the boiler from scaling and corrosion.
5. Automatic Control System
The boiler can be equipped with an integrated electrical or PLC-based control system for centralized monitoring and automatic operation. The system can monitor and control key operating parameters, including steam pressure, water level, temperature, induced and forced draft fans, fuel feeding, grate operation, combustion conditions, and other critical functions. This helps improve operational safety, combustion efficiency, system stability, and ease of operation.
