This series boiler adopts proven vertical double-drum design. The unit is clearly divided into two core modules: upper heat absorbing assembly of boiler body and lower chain grate combustion equipment, featuring neat layout and stable structure for convenient daily inspection and maintenance.
Membrane water-cooled walls are arranged on both furnace sides to improve furnace tightness and reduce air & heat leakage, while expanding furnace volume and heating area for complete fuel combustion. Valve-controlled secondary air devices are installed on front and rear furnace walls together with optimally proportioned front & rear arches. The large coverage of arches strengthens heat storage and stabilizes combustion temperature to maximize full burnout of biomass fuel and avoid fuel waste.
Continuous feeding combustion is realized via chain grate. Biomass fuel spreads evenly on the grate and burns steadily as the grate moves at constant speed. High-temperature flue gas generated flows through furnace, burnout chamber and convection tube bundles for multi-stage efficient heat exchange to release full heat energy. Cooled flue gas enters tail flue duct, purified by professional dust collector, conveyed under negative pressure by induced draft fan and discharged through chimney up to standard. The complete flue gas treatment system meets all industrial environmental emission standards.
Air Duct System: Equipped with multiple independent adjustable air chambers with manually controllable air volume, matching air demand of various biomass fuels and different combustion phases. Uniform horizontal wind pressure eliminates local incomplete combustion and maintains optimal combustion condition.
Water Circulation System: Cross-section ratio of risers and downcomers is optimized via professional thermal calculation for smooth circulation and stable flow velocity, free from steam-water imbalance or circulation stagnation in long-term operation. A large-capacity steam drum with complete internal high-efficiency steam-water separators improves steam dryness and stable steam quality.
Specially designed for clean biomass energy, compatible with wood chips, straw, rice husk, bamboo scraps and other agricultural & forest residues, serving as preferred eco-friendly industrial heat source.
Excellent environmental performance: Biomass waste as fuel generates minimal harmful flue gas and residue, realizing resource recycling of agricultural waste with low carbon emission, fully complying with local environmental policies and green production standards.
Lower operating cost: Biomass raw materials are low-priced and widely available. Combined with high-efficiency double-drum combustion structure, total operating cost can be cut by 5%~10%.
Wide fuel compatibility: Adjustable multi-chamber air distribution system supports various solid biomass fuels with strong versatility.
High-Efficiency Heat Exchange Structure
Convection heating surface delivers high heat transfer coefficient and stable long-term thermal efficiency. Double-drum design greatly improves fuel burnout rate to cut fuel consumption fundamentally.
Precision Manufacturing Technology
Chain grate panels and front/rear smoke box panels are all processed by CNC plasma cutting with high dimensional accuracy and narrow splicing gaps, resulting in neat appearance and greatly reduced air & ash leakage.
Staged Air Distribution Combustion Technology
Controllable secondary air on front and rear furnace walls plus segmented adjustable air chambers build staged oxygen supply combustion system, raising overall thermal efficiency and lowering discharge of smoke dust, carbon monoxide and other pollutants simultaneously.
Integrated intelligent electric control cabinet with complete interlock protection functions:
Automatic feed water regulation for stable drum water level
Audible & visual alarm for high/low water level, interlock shutdown on water shortage
Automatic pressure relief and interlock boiler stop against overpressure
Automatic fuel cut-off and alarm upon flameout
Linked multi-protection prevents safety hazards such as dry burning, overpressure and water shortage, no 24-hour on-site operator required.
Low vibration and steady operation fit 24-hour continuous steam production of factories;
Supports about 110% overload capacity of rated load to handle intermittent peak steam demand with strong fault tolerance;
High automation for one-click start/stop and load adjustment, reducing labor maintenance cost.
