Industrial Biomass Boiler: Features, Technology, and ZOZEN BOILER Solutions

Unlike conventional fossil fuel boilers, industrial biomass boilers are designed to utilize renewable solid fuels such as wood chips, agricultural residues, or biomass pellets. These boilers convert the chemical energy in biomass fuels into thermal energy, providing reliable steam or hot water for industrial processes while simultaneously reducing carbon emissions. Their efficiency, flexibility, and compatibility with a variety of biomass fuels make industrial biomass boilers an attractive choice for manufacturers aiming to improve energy efficiency and minimize environmental impact.

ZOZEN BOILER’s industrial biomass boilers are engineered with advanced combustion and heat transfer technologies to ensure stable operation, low emissions, and high thermal efficiency. With decades of experience in designing and manufacturing industrial boilers, ZOZEN has developed a series of biomass boiler solutions that can handle a wide range of biomass fuels while maintaining performance and reliability. The company’s focus on continuous innovation, rigorous quality control, and adaptation to regional fuel characteristics enables ZOZEN BOILER to offer industrial biomass boilers that are both effective and sustainable.

DZL Three-Drum Non-Ash-Accumulating Industrial Biomass Boiler

Among ZOZEN BOILER’s offerings, the DZL series three-drum non-ash-accumulating industrial biomass boiler represents a major advancement in biomass boiler technology. This boiler features a three-drum water tube structure, which optimizes the arrangement of the heating surfaces and flue gas pathways to ensure efficient heat transfer and stable steam generation. The three-drum configuration improves water circulation and facilitates high-pressure operation, making it suitable for industrial applications that demand continuous and consistent steam supply.

A core innovation in the DZL industrial biomass boiler is its non-ash-accumulating design. Traditional biomass boilers often face challenges with ash deposition on the convection heating surfaces, requiring frequent shutdowns for cleaning and maintenance. The DZL series addresses this issue through carefully engineered gas flow paths and heating surface configurations, allowing ash to pass through without accumulating. This design ensures that the boiler can operate for long periods without interruption, maintaining both efficiency and safety in industrial operations.

The DZL industrial biomass boiler employs a chain grate system combined with independent air chambers. This design enables precise control of the air supply to different sections of the furnace, ensuring thorough combustion of biomass fuels such as pellets, rice husks, wood chips, corn cobs, and sawdust. With this approach, the boiler can achieve thermal efficiency exceeding 87.5%, a crucial factor for industries seeking to reduce operational costs while maintaining high-quality steam production.

The structure of the DZL industrial biomass boiler is also optimized for heat recovery and environmental compliance. Water walls are arranged around the front section of the boiler to absorb radiation heat from the furnace, while convection tubes are located between the upper and lower drums to extract energy from high-temperature flue gases. The heat energy is further utilized in economizers and dust collectors before the gases are expelled through the chimney. This layout maximizes energy conversion from biomass fuel to steam while minimizing particulate emissions, helping industrial operators meet increasingly stringent environmental regulations.

DZL Industrial Biomass Boiler for a Cottonseed Oil Factory in Tanzania

The practical benefits of ZOZEN BOILER’s industrial biomass boiler are best illustrated through real-world applications. Recently, ZOZEN BOILER supplied a DZL series 20-ton industrial biomass boiler to a cottonseed oil factory in Tanzania to meet the facility’s steam and heat requirements. The factory needed a solution that could provide stable, continuous steam while reducing environmental impact, as well as ensuring operational efficiency and safety.

The DZL industrial biomass boiler supplied to the Tanzanian factory incorporates the third-generation design features described above, including a chain grate and independent air chambers. These features ensure that biomass fuels such as cotton stalk pellets, rice husks, and wood chips are completely burned, reducing waste and improving thermal efficiency. The boiler’s design allows for more than 87.5% heat efficiency, providing reliable and consistent steam to support the factory’s oil extraction and processing operations.

The water tube arrangement in the DZL industrial biomass boiler optimizes heat absorption from flue gases. The front of the boiler is surrounded by water-cooled walls, while the upper and lower drums feature convection tubes to capture the heat from high-temperature gases. The flue gases then pass through economizers and dust removal systems before being released, ensuring efficient energy use and compliance with emission standards. This workflow demonstrates how ZOZEN’s industrial biomass boiler technology integrates performance, fuel flexibility, and environmental compliance into a single system.

In addition to the technical advantages, ZOZEN BOILER provides comprehensive support for installation and commissioning. The DZL industrial biomass boiler for the Tanzanian cottonseed oil factory was delivered and is currently being assembled on-site, with ZOZEN engineers guiding the foundation and installation process. This hands-on support ensures that the boiler operates efficiently from the start, reducing the risk of delays or operational issues.

This project not only highlights ZOZEN BOILER’s expertise in industrial biomass boiler applications but also provides a sustainable, high-efficiency energy solution for the cottonseed oil industry. By choosing an industrial biomass boiler from ZOZEN, the factory benefits from reduced fuel costs, lower emissions, and a reliable steam supply that supports continuous production.
