Industrial production today relies heavily on steam and thermal energy. Boilers, as the primary equipment that generates these energy sources, exist in various configurations, capacities, and designs. Different boiler types are available in the market, each offering unique advantages and facing certain limitations depending on fuel, structure, and intended application.

For instance, gas and oil-fired boilers are known for their clean combustion and fast start-up, making them suitable for industries that require flexible operations. Biomass boilers utilize renewable agricultural and forestry residues, reducing dependence on fossil fuels and aligning with sustainability initiatives, though fuel storage and handling can add complexity. Coal-fired boilers remain widely used in regions with abundant coal resources due to their stable performance and adaptability to load fluctuations, though they must meet strict environmental regulations. Thermal oil boilers, designed for indirect heating with organic heat transfer media, provide uniform heating at high temperatures without the need for high-pressure steam, which is valuable in chemical, building materials, and textile processes.

Understanding the advantages and trade-offs of these boiler types helps enterprises make informed decisions about investment and operation. ZOZEN Boiler, with more than three decades of expertise, provides advanced solutions across multiple boiler categories, ensuring efficiency, safety, and reliability for diverse industrial users.

ZOZEN Product Lines: WNS, DZL, SZL, and YQW

Among the wide range of boiler types developed by ZOZEN, four models stand out for their technological innovation, robust design, and adaptability to various industries: the WNS gas/oil-fired boiler, the DZL biomass boiler, the SZL coal-fired boiler, and the YQW thermal oil boiler.

The WNS series gas/oil-fired steam boiler features a horizontal, shell-type, wet-back construction with a full corrugated furnace. In the 1–20 ton range, the WNS design provides sufficient combustion space, ensuring fuel and air mix completely for efficient burning. Its wet-back structure minimizes heat loss while enhancing reliability under continuous operation. Advanced low-NOx burners further reduce nitrogen oxide emissions, supporting enterprises that face strict emission requirements. The boiler can achieve thermal efficiency levels exceeding 98% under optimized configurations, and its intelligent control system offers automated, stable operation. Industries such as textiles, chemicals, and food processing benefit from the high-quality steam generated by this boiler type.

The DZL series biomass steam boiler adopts a single-drum longitudinal arrangement with a chain grate system. Its furnace volume is enlarged to accommodate a variety of biomass fuels, including rice husks, wood chips, palm residues, and agricultural pellets. The boiler is equipped with membrane water-cooling walls and a convection heating surface, ensuring strong heat absorption and stable operation even with fuels of high moisture content. This boiler type is particularly suitable for enterprises engaged in agricultural processing, food production, and regions with abundant biomass resources. With optimized furnace arch design, the DZL boiler improves fuel adaptability while reducing ash accumulation, thus prolonging operational cycles.

The SZL series coal-fired steam boiler adopts a double-drum vertical arrangement with a chain grate furnace. In the 6–35 ton range, the SZL boiler type provides a large heating surface, efficient water circulation, and a well-structured convection section. Its furnace chamber is lined with water-cooled walls, increasing the effective radiation absorption area. The independent air chamber and damper design allows precise air distribution, ensuring efficient coal combustion. This boiler is widely applied in building materials, chemical production, and paper manufacturing, where steady and reliable steam output is critical.

The YQW series thermal oil boiler provides indirect heating through an organic heat transfer medium. Unlike traditional steam boilers, this boiler type delivers high temperatures at low pressure, reducing risks associated with high-pressure operations. Its horizontal coil design ensures large heat transfer area and low thermal stress, enhancing equipment safety. The system is designed with a fully automatic control package, supporting precise temperature regulation across production lines. Applications for this boiler include petrochemical processes, synthetic fiber production, and construction material manufacturing, where stable and uniform heat supply is required.

By combining structural design with advanced combustion technology, ZOZEN has ensured that these boiler types not only meet the technical needs of customers but also align with environmental and economic requirements.
