In the industrial sector, a factory boiler is often the central source of thermal energy, providing steam or heat required for production processes. Across the market, different types of factory boilers are available, each designed to meet particular fuel conditions, efficiency demands, and industrial applications. Broadly, these boilers fall into categories such as gas and oil-fired steam boilers, coal-fired steam boilers, biomass-fired steam boilers, and circulating fluidized bed boilers.

The advantage of modern factory boilers lies in their ability to deliver stable and continuous thermal energy while reducing operating costs. Gas and oil-fired boilers, for example, provide cleaner combustion and higher efficiency, making them suitable for industries in regions with strict environmental regulations. Biomass-fired boilers help companies take advantage of renewable resources, lowering dependence on fossil fuels. Coal-fired boilers, although traditional, are valued in markets with stable coal supply and cost sensitivity. Fluidized bed boilers allow for multi-fuel adaptability and stable combustion of even low-grade fuels.

It is in this context that ZOZEN Boiler has built its reputation. With more than three decades of experience, ZOZEN offers a full portfolio of factory boilers designed with advanced engineering, modern safety features, and international compliance. By combining a wide product range with professional project support, ZOZEN has become a reliable partner for industries worldwide seeking stable and efficient factory boiler solutions.

ZOZEN Boiler Product Portfolio

The WNS series is a horizontal, shell-type, wet-back factory boiler designed for stability and high efficiency. Its furnace adopts a full-corrugated design that enhances both heat transfer and structural reliability. The boiler applies a three-pass configuration, with threaded smoke tubes that enlarge the heating surface and improve flue gas flow.In practical operation, the WNS boiler reaches efficiency levels close to 98% with economizers and condensers integrated into the system. The steam it produces has excellent dryness, making it suitable for industries such as food processing, textiles, and pharmaceuticals. The intelligent control system ensures real-time monitoring of parameters including water level, pressure, and fuel input, reducing operator workload while improving safety.

The DZL three-drum series demonstrates ZOZEN’s innovation in biomass boiler design. With its chain-grate structure, the boiler accommodates a wide variety of biomass fuels such as wood chips, rice husks, and agricultural residues. The three-drum design enhances water circulation and improves the stability of steam output.The furnace is lined with membrane water walls that increase the radiation heating surface while minimizing heat loss. Its combustion efficiency consistently exceeds 88%, while automated fuel feeding and ash removal systems simplify daily operations. For industries located in regions with abundant biomass resources, this boiler offers a cost-effective and environmentally responsible solution.

For clients with access to coal resources, the SZL series double-drum, chain-grate factory boiler is a practical choice. Its design includes large furnace volume and membrane water walls that optimize heat absorption and minimize air leakage. The furnace adopts zoned air supply, enabling precise combustion control and better fuel utilization.The SZL boiler delivers thermal efficiency above 81% and provides flexible capacity to meet the demands of paper, chemical, and building material industries. Its assembly structure simplifies transportation and installation, ensuring stable performance even under high-load conditions.

The SHX series represents ZOZEN’s strength in advanced combustion technology. Circulating fluidized bed boilers are known for their ability to handle multiple fuel types, including low-grade coal, biomass blends, and industrial by-products. The SHX boiler maintains stable combustion through high-temperature bed material and uniform mixing of fuel and air.Its circulating system ensures better fuel burnout and lower emissions compared with conventional coal-fired boilers. The membrane water wall and cyclone separator design enhance heat utilization and efficiency. With wide load adjustment capabilities and strong adaptability, the SHX boiler is often applied in large-scale industrial projects requiring continuous and flexible steam output.

Unlike steam boilers, the YQW thermal oil boiler provides high-temperature heating at relatively low system pressure. This feature ensures safety while meeting industrial processes that demand precise temperature control. The horizontal coil structure within the YQW series guarantees uniform heat transfer, and the advanced combustion system ensures stable flame performance.The thermal efficiency of the YQW boiler exceeds 92% when equipped with energy-saving components. Industries such as chemicals, plastics, and textiles benefit from its ability to maintain consistent process temperatures without pressure fluctuations. Safety systems, including temperature and flow monitoring, protect both the equipment and operators, ensuring long-term reliability.
