Introduction
The DZL series third-generation biomass boiler is a water tube boiler composed of three drums. It is independently developed by ZOZEN Boiler and has independent intellectual property rights. The boiler adopts a modular structure, consisting of two large components, the upper and lower parts.
- Tall furnace design
- Increased furnace height (1-3m)
- Meets non-formed biomass fuel combustion requirements
- Maintenance Platform
- Grid-plate escalator for enhanced strength and rigidity
- Strategic layout for easy access to every maintenance point
- High thermal efficiency
- Minimal dead zones in flue gas scouring
- Reduced vortex formation on heat transfer surface
- Rational furnace grate configuration
- Optional chain grate or reciprocating grate for various biomass fuels
- High-temperature resistant grate bars
- Ash-blowing device
- Ash-blowing device on tail convection surface with furnace-top tube hole
- Adaptable ash-blowing types for fuels; ash removal without shutdown
- Convection heat surface
- Reduces dust collector load for enhanced environmental protection
- Rationally arranged ash-cleaning doors for thorough maintenance
- Combustion and Cooling Chambers
- Full-seal, water-cooled membrane walls
- Front-back arch furnace, ignition and flame-leading arches
Advantages
-
Wide fuel adaptability
It uses biomass pellets, rice husks, wood chips, corn cobs, and sawdust
-
Sufficient fuel combustion
The chain grate with a separateair chamber ensure full combustion.
-
Thermal Efficiency≥87.5%
The furnace's dense, water-cooled tubes provide a vast radiation area
-
Easy operation and maintenance
Advanced controls automate fuel, ash removal, and slag discharge, streamlining operations
