Reliable Steam Solutions with a 4 Ton Boiler from ZOZEN

Industrial production relies heavily on efficient and stable steam supply, and choosing the right boiler plays a crucial role in ensuring both productivity and energy savings. Among the most widely used units is the 4 ton boiler, a medium-capacity solution suitable for industries requiring a steady flow of high-quality steam while balancing investment and operating costs.

A 4 ton boiler is commonly used in paper manufacturing, food processing, textile production, chemical industries, and other sectors where steam is indispensable for heating, drying, sterilization, or as part of the production process. Its moderate capacity makes it ideal for small to medium-sized factories that need reliable performance without the scale of larger industrial plants. With growing demand for energy efficiency and sustainable operation, modern designs of the 4 ton boiler have evolved to deliver not only stable steam output but also reduced emissions and higher fuel adaptability.

Within this context, ZOZEN Boiler has established itself as a trusted global manufacturer, offering advanced solutions that combine technical precision, energy efficiency, and environmental responsibility. ZOZEN’s product line includes biomass-fired and oil/gas-fired boilers, with the 4 ton capacity range being one of the most popular due to its adaptability across industries.

ZOZEN 4 Ton Boiler Product Range

ZOZEN provides several types of boilers in the 4 ton capacity, but two models in particular stand out: the DZL single-drum biomass steam boiler and the WNS oil/gas-fired steam boiler. Each is tailored to specific fuel conditions and customer requirements while maintaining high efficiency and reliability.

The DZL series is designed to make the most of renewable fuels, particularly biomass. In the 4 ton configuration, this boiler employs a single-drum water tube structure with natural circulation. The furnace is equipped with water-cooled walls connected to the upper drum and lower headers, forming a stable combustion chamber that improves heat absorption.One of the distinctive aspects of the DZL biomass boiler lies in its fuel flexibility. It can efficiently burn wood chips, rice husks, agricultural residues, and forestry by-products, making it a highly adaptable choice for regions where biomass resources are abundant. For the 4 ton boiler size, the furnace volume has been carefully optimized to ensure complete combustion of non-uniform fuels, providing steady steam output with reduced unburned carbon.The grate system is another critical feature. The DZL boiler incorporates a chain grate that allows continuous feeding and burning of biomass fuel. Combined with a scientifically arranged air distribution system, this design achieves higher combustion efficiency while reducing particulate emissions.

The WNS series 4 ton boiler represents ZOZEN’s expertise in fire-tube boiler design. It is a horizontal, internal combustion, fully packaged steam boiler that operates on natural gas, light oil, or dual fuel. The design features a wet-back three-pass structure, which maximizes heat transfer by directing flue gases through corrugated furnace tubes and threaded smoke tubes.The use of advanced low-NOx burners ensures complete fuel combustion while controlling emissions, with nitrogen oxide emissions kept below stringent international limits.Another advantage of the WNS design is the integration of intelligent control systems. Equipped with an automatic control cabinet, the 4 ton WNS boiler monitors water level, steam pressure, and fuel supply in real time. Safety devices, such as pressure relief valves and water shortage alarms, provide additional reliability, making it suitable for continuous industrial operation.In addition, the compact structure and pre-assembled delivery simplify installation, which is particularly beneficial for companies requiring fast commissioning and minimal downtime.

H&Y Wood Company in Côte d’Ivoire

A practical example of how the 4 ton boiler contributes to industrial development can be seen in the experience of H&Y Wood Company, a paper manufacturing enterprise based in Côte d’Ivoire. With production expanding and energy demand rising, the company was actively searching for a sustainable and efficient solution to support its growing operations. After extensive market evaluation, the management selected ZOZEN Boiler’s DZL series biomass steam boiler in a 4 ton capacity.

The decision was motivated by the company’s commitment to sustainable energy. Biomass, particularly wood chips, was readily available from their own processing activities, offering a cost-effective and environmentally friendly fuel source. The DZL single-drum boiler’s adaptability to wood-based fuels made it an ideal match for their requirements.

During installation, H&Y Wood Company encountered certain challenges. While their team had some prior experience with boiler systems, they lacked specialized knowledge in the proper setup and operation of biomass boilers. Throughout the process, ZOZEN’s after-sales team provided continuous support. Technical experts offered detailed instructions, operational guidelines, and maintenance recommendations, ensuring the system was installed correctly and ran safely.

The responsiveness of ZOZEN’s service staff was highly appreciated. The team addressed each query in a timely manner and even guided local operators on optimizing fuel feeding and air distribution to achieve the best performance. As a result, the 4 ton DZL biomass boiler quickly became a reliable energy backbone for H&Y’s production line.

Once operational, the boiler provided consistent steam supply with noticeable improvements in fuel utilization efficiency. By using wood chips as the primary fuel, the company not only lowered its energy costs but also reduced its carbon footprint, reinforcing its reputation as an environmentally responsible enterprise. The project demonstrated how ZOZEN’s 4 ton boiler could successfully combine sustainability with industrial productivity.
