In the global energy transition, the demand for clean and renewable fuels has increased significantly. Biomass has become an important alternative to traditional fossil fuels due to its renewable nature, wide availability, and relatively low carbon footprint. When used in biomass boilers fuel systems, these resources provide reliable steam and heat for a variety of industrial applications. Unlike coal or oil, biomass fuels are derived from organic matter such as agricultural residues, forestry by-products, and dedicated energy crops, making them sustainable and adaptable to local resources.

The core advantage of biomass boilers fuel lies in its flexibility. Enterprises can select from a wide range of biomass types depending on cost, local supply, and combustion requirements. This adaptability has encouraged industries such as food processing, textiles, paper manufacturing, pharmaceuticals, agriculture, and livestock processing to adopt biomass boilers.In response to the growing demand for efficient biomass boiler systems, ZOZEN Boiler has developed advanced solutions that integrate modern combustion technology with practical engineering design.

Specifications and Advantages of ZOZEN DZL Three-Drum Biomass Steam Boiler

Structurally, the DZL biomass boiler adopts a three-drum, water tube configuration, which significantly increases the heating surface area. This arrangement improves heat absorption efficiency and ensures the stable separation of water and steam. The furnace is equipped with densely arranged water-cooled walls, expanding the radiation heat transfer area and enhancing overall thermal performance. Under standard operating conditions, the thermal efficiency of the DZL boiler exceeds 88%, ensuring reduced fuel consumption and lower operating costs.

The combustion system is specifically optimized for biomass boilers fuel. A flexible grate system allows for different types of biomass fuels to be burned efficiently. Whether using biomass pellets, rice husks, corn stalks, sawdust, or other agricultural residues, the boiler can be adapted with customized grate designs to achieve full combustion. The unique aerodynamic layout, combined with independent wind chamber control, provides precise air distribution at different combustion stages. This not only promotes complete burning of biomass fuels but also reduces unburned carbon in ash, improving fuel utilization.

Another significant advantage of the DZL series lies in its ability to reduce fouling and ash deposition. The boiler incorporates an innovative flue gas flow design that minimizes dead zones and prevents vortex formation in convection heating areas. This reduces the risk of ash accumulation, which is a common issue in biomass boilers, and ensures long-term stable heat transfer efficiency. Additionally, the boiler features a real-time ash discharge system. Ash particles carried by flue gas are guided into dedicated hoppers and discharged through rotary ash valves, reducing maintenance workload and extending the continuous operating cycle.

Automation and intelligent controls are also integrated into the DZL biomass boiler. Key parameters such as steam pressure, temperature, and feedwater levels are monitored in real time. The control system manages automatic fuel feeding, slag removal, and ash discharge, significantly lowering labor intensity while ensuring safe and reliable operation.

Types of Biomass Boilers Fuel and Combustion Efficiency

The diversity of biomass boilers fuel provides both opportunities and challenges for industrial users. Common fuel types include biomass pellets, rice husks, wood chips, sawdust, palm shells, corn stalks, and other agricultural by-products. Each has its unique advantages and limitations.

Biomass pellets, with their standardized shape and low moisture content, are widely favored due to their high calorific value and stable combustion characteristics. Rice husks and palm shells are often abundant in agricultural regions, offering low-cost fuel options, though their high silica or ash content can increase wear on furnace components. Wood chips and sawdust provide good combustion performance but may require pretreatment to ensure uniform size and reduced moisture content. Corn stalks and other crop residues are cost-effective and locally available but tend to have higher moisture levels, which can reduce combustion efficiency if not properly managed.

The combustion efficiency of biomass boilers fuel largely depends on furnace design and air distribution technology. ZOZEN’s DZL three-drum biomass boiler incorporates a chain grate and segmented wind chamber system that allows precise control of airflow across drying, combustion, and burnout zones. By adjusting air volume and temperature in each stage, the boiler ensures efficient ignition and complete combustion even for fuels with higher moisture content.

Another factor that improves combustion efficiency is the optimized furnace geometry and aerodynamic design. The streamlined flow of flue gas reduces heat loss and maximizes contact with heating surfaces, improving thermal transfer. Together with the water-cooled wall structure and convection heating surface layout, these innovations enable the DZL boiler to achieve consistently high efficiency across different biomass fuel types.
