As environmental concerns and energy costs increase, industries are increasingly turning to renewable energy sources to reduce carbon emissions and improve operational efficiency. In this context, the biomass fuel boiler has emerged as a practical solution, offering clean, renewable energy conversion from locally available biomass resources into stable steam. By utilizing solid organic materials such as wood chips, agricultural residues, and other sustainable feedstocks, biomass fuel boilers provide a balance between environmental responsibility and operational performance.

Biomass fuel boilers can be classified based on their combustion and structural design, primarily into water-tube and fire-tube types, as well as chain-grate and reciprocating-grate systems. Water-tube biomass fuel boilers generally offer higher pressure and temperature capabilities, making them suitable for large-scale industrial operations, whereas fire-tube designs provide a simpler construction and are often applied in medium-capacity settings. Chain-grate biomass boilers, in particular, allow for continuous feeding of solid biomass fuels and support steady combustion, which is essential for industries requiring uninterrupted steam supply. Within this technical landscape, ZOZEN Boiler has developed a strong reputation as a manufacturer capable of delivering advanced biomass fuel boiler systems that align with both performance requirements and sustainability goals.

ZOZEN SZL Series Biomass Fuel Boiler: Fuel Options, Technical Features, and Advantages

Among ZOZEN’s biomass fuel boiler offerings, the SZL series stands out as a versatile and efficient solution for industrial steam generation. SZL boilers are horizontal, double-drum, water-tube systems equipped with a chain-grate combustion mechanism. This design provides a robust platform for burning a wide range of biomass fuels, ensuring consistent steam output while maintaining high thermal efficiency.

The SZL biomass fuel boiler is compatible with numerous locally sourced solid fuels, including wood chips, rice husks, agricultural residues, and palm shells. These fuels offer a renewable alternative to fossil energy, allowing enterprises to reduce energy costs and achieve environmentally conscious operations. The design of the SZL boiler specifically addresses the variability in fuel calorific value, moisture content, and combustion characteristics. The chain-grate feeding system ensures uniform distribution of fuel across the furnace, while independent air chambers and adjustable air doors allow precise control of oxygen supply throughout the combustion process. This enables operators to optimize combustion for different fuel types, reduce unburned carbon, and maintain stable steam parameters.

The SZL series adopts a horizontal double-drum structure with longitudinal arrangement, providing a combination of radiant and convective heating surfaces. Membrane water walls around the furnace absorb radiant heat effectively, while threaded smoke tubes enhance convection heat transfer. The resulting heat utilization contributes to thermal efficiency exceeding 86% under properly prepared fuel and optimal operation. Low carbon content in the ash and minimal slag formation are additional benefits, reducing the frequency of maintenance and prolonging operational periods.

Furthermore, SZL biomass fuel boilers are equipped with exhaust gas handling and dust collection systems that comply with local environmental regulations, ensuring that industrial operations can maintain a low emission profile. This design consideration is particularly important for enterprises seeking to integrate sustainable energy use with regulatory compliance. The combination of fuel flexibility, thermal efficiency, and emission control positions ZOZEN SZL biomass fuel boilers as a reliable choice for industries evaluating long-term investment in steam generation.

SZL Biomass Fuel Boiler for PT Pakan Sehat Unggul (PT PSU)

A representative case of ZOZEN’s biomass fuel boiler deployment is PT Pakan Sehat Unggul (PT PSU), a leading poultry feed and livestock product enterprise in Indonesia. In the poultry feed industry, steam is a critical medium for multiple stages of production, including raw material sterilization, cooking, and blending. The stability, efficiency, and environmental impact of the steam supply system directly affect both product quality and production efficiency, making a reliable boiler solution essential for operational success.

PT PSU faced the challenge of maintaining continuous steam supply while optimizing energy consumption through the use of locally available biomass resources, particularly palm shells. Palm shells are widely available in Indonesia as an agricultural by-product and possess high calorific value with relatively low ash content. However, their combustion characteristics require specialized boiler design, particularly regarding the grate structure and combustion system, to ensure complete burning and minimal operational issues.

To meet these specific requirements, Wuxi ZOZEN Boiler Co., Ltd. customized the SZL10-1.25-SS biomass fuel boiler for PT PSU, optimized for palm shell combustion. The boiler adopts a horizontal double-drum, longitudinal arrangement with an advanced chain-grate system. The grate design ensures uniform fuel distribution and stable combustion, reducing the occurrence of slagging and fuel blockage. Air supply is managed through multiple independent air chambers, allowing operators to adjust airflow to match fuel characteristics and load requirements, ensuring that combustion remains efficient under varying operating conditions.

The SZL10-1.25-SS biomass fuel boiler achieved a thermal efficiency of over 86%, reflecting thorough fuel utilization and stable steam production. The ash content in the residues remained low, indicating complete combustion and minimal waste. Dust collection and emission control systems supplied with the boiler ensured compliance with local environmental regulations, enabling PT PSU to operate sustainably without concerns over emissions or regulatory penalties.
