The WNS series represents ZOZEN’s response to industries requiring clean, efficient, and automatically operated boilers. This horizontal, internal combustion, full wet-back boiler uses a large corrugated furnace design, which enhances combustion efficiency and thermal expansion flexibility.The WNS steam boiler China design features a three-pass structure. High-temperature flue gases flow through corrugated flue tubes, maximizing heat transfer area and improving overall efficiency. The integrated condenser and economizer enable the boiler to recover latent heat from exhaust gases, significantly reducing fuel consumption and emission levels.

Key technical features include:

Thermal efficiency reaching over 98% with economizer and condenser configuration.

Operating pressure range of 0.7–2.5 MPa, suitable for a variety of production processes.

High automation level, with advanced PLC control systems ensuring precise pressure and temperature regulation.

Low NOx burners, designed to reduce nitrogen oxide emissions to comply with international environmental standards.

This series has been successfully deployed in industries such as chemical fiber, food processing, and textiles, where consistent steam output and environmental compliance are critical.

ZOZEN 10 ton WNS gas-fired steam boiler

As renewable energy utilization grows, biomass steam boilers have become an essential part of the steam boiler China market. ZOZEN’s DZL series single-drum biomass boiler integrates a compact structure and optimized furnace design to achieve stable combustion and high efficiency using various biomass fuels such as wood chips, rice husks, and pellets.The DZL series features a chain grate combustion system that enables uniform fuel feeding and automatic ash removal. Its furnace arch and flue gas flow path are designed to enhance turbulence and prolong the residence time of flue gases, ensuring complete fuel combustion and improved thermal efficiency.

Technical features and advantages:

Evaporation capacity ranges from 2 to 10 tons per hour, adaptable to different plant scales.

Water-cooled walls and convective heating surfaces maximize heat absorption while maintaining structural integrity.

Low operating costs, as biomass fuels are generally more economical and sustainable compared with fossil fuels.

This boiler is particularly suited for agricultural processing plants, feed production facilities, and wood product industries, which can use local biomass waste as a cost-effective fuel source.

The SZL series continues to be one of ZOZEN’s classic designs in the steam boiler China segment. This series is characterized by its double-drum, vertically arranged, chain-grate structure, allowing for efficient fuel combustion and easy maintenance.The boiler body consists of upper and lower drums, connected by a system of convection tubes and water-cooled walls. The combustion chamber adopts a membrane wall design, which ensures low heat loss and enhances boiler durability. The flue gas passes through several convection passes before entering the economizer, maximizing heat recovery and improving efficiency.

Key parameters:

Evaporation capacity: 6–35 t/h

Steam temperature: 184 – 350℃

Thermal efficiency: ＞ 81%

The SZL boiler’s robust performance, combined with easy installation and adaptability to various coal types, makes it a popular choice among heavy industrial sectors such as mining, construction materials, and metallurgy.

ZOZEN Steam Boiler Supporting Clean Energy in Coal Processing

A large coal enterprise with an annual output exceeding 10 million tons partnered with ZOZEN Boiler to enhance its steam supply system. The company operates across multiple high-altitude locations, where oxygen levels are lower, making stable combustion more challenging. Its production lines for coal washing and drying require a consistent and reliable steam source to ensure process quality and efficiency.

The client faced several operational challenges common in the industry:

Fluctuating loads, caused by intermittent processing cycles.

High-altitude operation, reducing combustion efficiency and affecting emissions.

Strict environmental compliance, with tighter NOx emission limits and lower energy consumption targets.

To address these challenges, ZOZEN supplied a 10-ton WNS series gas-fired steam boiler equipped with a low-NOx burner, economizer, and condenser. The integrated waste heat recovery system not only utilized residual heat from exhaust gases but also recovered latent heat from condensed steam vapor, increasing feedwater temperature and reducing fuel consumption.

The result was a reliable and energy-efficient steam system capable of maintaining stable pressure and temperature under variable loads. The client reported improved steam quality, lower gas consumption, and a noticeable reduction in emissions, aligning with both productivity and sustainability goals.
