Introduction
The DZW series third-generation biomass boiler is a water tube boiler composed of three drums. It is independently developed by ZOZEN Boiler. The boiler adopts a modular structure, consisting of two large components. The upper large part is the heating surface of the main body, and the lower large part is the combustion equipment.
- 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
- Rational furnace grate configuration
- We configure reciprocating grates to handle high-moisture fuels.
- We improve reliability with 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
- High thermal efficiency
- Minimal dead zones in flue gas scouring
- Reduced vortex formation on heat transfer surface
Advantages
-
Wide fuel adaptability
It uses biomass bulk fuel, formwork, wood chips, palm shells, etc.
-
Sufficient fuel combustion
The reciprocating grate with a separate air chamber is suitable for high-moisture fuels
-
Thermal Efficiency＞86%
The furnace's dense, water-cooled tubes provide a vast radiation area
-
Easy operation and maintenance
Advanced control system with high automation levels for fuel supply, ash discharge, and slag discharge operations.
