Thermal Capacity: 2 – 10 t/h
Working Pressure: 1 – 2.5 MPa
Design Features:
Unique three-pass water-fire tube design that solves the issue of tube plate cracking in pure fire tube boilers.
Equipped with an independent high-pressure secondary fan for precise control and adjustment of air volume and pressure.
SZL Series Double-Drum Longitudinal Chain Grate Boilers
The SZL series biomass boilers are designed based on international advanced technology and experience. These horizontal double-drum, longitudinally arranged boilers are highly efficient and reliable.
Thermal Capacity: 6 – 35 t/h
Working Pressure: 1 – 2.5 MPa
Design Features:
High degree of mechanization: Advanced control systems with automated fuel supply, ash removal, and slag discharge make operation simple and efficient.
Customizable boiler systems: Tailored feeding systems, ash discharge systems, and flue gas treatment systems provide cost savings and ease of use for clients.
DZL Series Three-Drum Biomass Fuel Boilers
The DZL series boilers feature a unique “A” structure with three drums, solving the issue of ash accumulation in the lower drum of traditional double-drum boilers. This product has made ZOZEN one of the leading China biomass boiler manufacturers.
Thermal Capacity: 15 – 40 t/h
Working Pressure: 1.25 MPa / 1.6 MPa / 2.5 MPa
Design Features:
Thermal efficiency > 87.5%: The chain grate design and independent wind chambers ensure complete fuel combustion.
Extended furnace height and increased residence time for biomass combustible gases enhance combustion efficiency.
Water-cooled walls control furnace temperatures below 850°C to reduce NOx formation.
Successful Partnership with the Mining Industry
ZOZEN, as one of the most reliable China biomass boiler manufacturers, recently supplied an SZL series biomass boiler to a mining enterprise, leveraging its advantages in thermal efficiency and environmental performance. The boiler’s double-drum longitudinal layout and water-cooled walls around the combustion chamber offer high heat transfer coefficients, low heat loss, and excellent airtightness. The chain belt grate design, combined with independent wind chambers and adjustable air doors, ensures precise air distribution and complete fuel combustion. This results in thermal efficiency exceeding 88%, with all performance indicators meeting international advanced levels.
