Comprehensive Steam Boiler Portfolio

ZOZEN's product range reflects decades of engineering expertise and market understanding. The company specializes in steam boilers, hot water boilers, and thermal oil heaters, with their steam boiler lineup demonstrating particular versatility and innovation.

Gas-Fired and Oil-Fired Steam Boilers

The WNS series gas-fired steam boilers represent ZOZEN's commitment to efficiency and compact design. Available in capacities ranging from 1 to 20 tons per hour with pressure ratings between 0.7 and 2 MPa, these horizontal boilers feature three-pass wetback structures that maximize heat transfer efficiency. The design incorporates corrugated furnaces that enhance turbulence and heat absorption while maintaining structural integrity under high temperatures.

ZOZEN also provides skid-mounted steam boiler solutions in the WNS series for applications requiring rapid deployment. These pre-assembled units arrive ready for quick installation and commissioning, significantly reducing time and costs.

For larger industrial applications, the SZS series offers capacities from 2 to 110 tons per hour with pressure capabilities reaching 5.3 MPa. This double-drum water-tube configuration provides superior steam generation for power plants, chemical facilities, and large manufacturing operations. The membrane water-wall structure ensures uniform heat distribution and reduces thermal stress, extending operational lifespan.

Biomass-Fired Steam Boilers

Recognizing the growing importance of renewable energy, ZOZEN manufactures specialized biomass-fired steam boilers that accommodate various agricultural residues and wood waste, supporting sustainable energy initiatives while delivering reliable steam generation.

The SZL series biomass-fired steam boilers (6 to 35 tons per hour) feature chain grate combustion systems with water-cooled walls, providing efficient heat absorption and stable operation. The double-drum vertical layout optimizes space utilization while maintaining high thermal efficiency.

The DZL series biomass boilers offer flexible configurations. The standard DZL models (2 to 10 tons per hour) provide quick-installation designs with automated fuel supply, ash removal, and slag discharge systems. The advanced DZL horizontal type series (10 to 40 tons per hour) represents ZOZEN's third-generation design with independent intellectual property rights, featuring a three-drum assembly structure that prevents ash accumulation while simplifying maintenance and enhancing combustion efficiency.

The DZW series reciprocating grate biomass boilers address high-moisture fuel challenges, offering enhanced fuel adaptability for varying biomass conditions across industries from food processing to textile manufacturing.

Coal-Fired Steam Boilers

For regions where coal remains an economically viable fuel source, ZOZEN provides specialized coal-fired solutions designed for efficiency and emissions control.

The DZL series coal-fired steam boilers (2 to 10 tons per hour) accommodate bituminous coal, lean coal, and anthracite. The horizontal three-pass water-fire tube construction with lightweight chain grates ensures thorough combustion while maintaining compact dimensions suitable for medium-capacity applications.

The SZL series coal-fired boilers (6 to 35 tons per hour) employ double-drum configurations with water-cooled furnace walls that improve radiation heat absorption. The chain grate system with independent air chambers enables precise combustion control across varying coal qualities.

For advanced emissions management, the DHX circulating fluidized bed (CFB) steam boiler achieves cleaner coal combustion through suspended particle technology. This system burns coal more completely at lower temperatures, reducing nitrogen oxide formation while accommodating variable fuel quality—addressing environmental concerns without sacrificing performance.
