In many small and medium-sized manufacturing facilities, a 1.5 mw biomass boiler represents a balanced solution between sufficient thermal output and controlled investment cost. This capacity level is widely applied in food processing, agricultural product treatment, wood processing, and light industry sectors where stable steam supply is essential for daily production. A 1.5 mw biomass boiler typically provides continuous thermal energy for blanching, sterilization, drying, heating, and other temperature-sensitive processes. As industries place greater emphasis on renewable energy utilization and emission reduction, biomass boilers have become an important direction in energy planning.

ZOZEN BOILER has accumulated extensive experience in biomass combustion technology and boiler manufacturing, offering reliable solutions for customers seeking a high-performance 1.5 mw biomass boiler. Through optimized structural design and refined combustion systems, ZOZEN ensures that biomass energy can be converted into stable steam output suitable for continuous industrial production.

Technical Features of ZOZEN DZL Single-Drum Biomass Steam Boiler

When discussing a 1.5 mw biomass boiler, the DZL series single-drum biomass steam boiler from ZOZEN is a representative configuration widely applied in practical projects. The DZL series adopts a single-drum longitudinal layout combined with a chain grate combustion system. This structure integrates the furnace and convection heating surfaces in a compact arrangement, ensuring efficient heat transfer while maintaining stable mechanical performance.

ZOZEN DZL series biomass-fired steam boiler

The combustion method of the DZL boiler is chain grate layered combustion. Fuel is evenly distributed onto the grate and moves forward steadily as the grate rotates, allowing the biomass to pass through drying, ignition, combustion, and burnout stages in sequence. ZOZEN engineers carefully analyze different biomass fuel characteristics and combine them with actual operating requirements. Based on these analyses, key parameters such as the hopper design, grate width and length, grate reducer rotation speed, and the position and direction of secondary air inlets are optimized. This tailored configuration enables biomass pellet fuel to burn more completely, improving combustion efficiency and reducing unburned carbon loss. Such design refinement is particularly important for a 1.5 mw biomass boiler operating under varying fuel conditions.

To enhance heat transfer performance, the DZL series biomass steam boiler incorporates threaded smoke tubes independently developed by ZOZEN. The heat transfer coefficient of these threaded tubes is approximately 1.8 times that of ordinary smoke tubes, which significantly strengthens convection heat exchange. Through this optimized heat exchange structure, the thermal efficiency of the DZL biomass boiler can reach above 88% under proper operating conditions. For enterprises evaluating a 1.5 mw biomass boiler, this level of efficiency contributes to lower fuel consumption per unit of steam produced.

The boiler body is equipped with water-cooled wall tubes arranged to strengthen radiant heat absorption within the furnace. The rational flue gas flow path reduces resistance while ensuring sufficient residence time for heat exchange. In addition, the control system allows automatic regulation of fuel feeding and air supply, helping maintain stable steam pressure and temperature. These technical features make the DZL series a practical and reliable option for companies considering the installation of a 1.5 mw biomass boiler for long-term operation.

Case Study: DZL Biomass Steam Boiler in Agricultural Product Processing

In agricultural product processing, operations such as blanching and sterilization depend heavily on stable industrial steam. A boiler with sufficient output and reliable heat supply directly influences daily production continuity. After multiple in-depth discussions with ZOZEN’s professional technical team, a food processing enterprise decided to purchase a DZL series biomass steam boiler to support its production activities. The project reflected the typical application scenario of a 1.5 mw biomass boiler, where steady steam generation is essential for maintaining product quality and processing efficiency.

The DZL biomass steam boiler supplied to the client adopted a single-drum longitudinal structure with chain grate layered combustion. ZOZEN engineers conducted detailed analysis of the biomass fuel characteristics and combined this with the user’s specific steam demand. Adjustments were made to the feeding hopper configuration, grate dimensions, grate speed, and secondary air arrangement. Through these targeted optimizations, biomass pellets could burn more thoroughly, enhancing combustion efficiency and reducing heat loss caused by incomplete burning.

For a processing enterprise, stable steam pressure and temperature are essential to ensure consistent blanching and sterilization results. The threaded smoke tube design used in the DZL boiler increased the convection heat transfer coefficient by approximately 1.8 times compared with conventional smoke tubes. With overall thermal efficiency reaching above 88%, the 1.5 mw biomass boiler was capable of meeting the enterprise’s daily production requirements without excessive fuel consumption.

The chain grate system provided smooth and continuous fuel advancement, ensuring that the combustion process remained stable even during long operating cycles. Meanwhile, the automated control system simplified operation and reduced manual intervention, allowing plant operators to focus on production management rather than constant boiler adjustments. Through this customized configuration, the 1.5 mw biomass boiler delivered consistent steam output to support blanching, sterilization, and other critical processes in the agricultural product processing line.
