As industrial sectors worldwide accelerate their shift toward cleaner energy, more companies are adopting high-efficiency biomass boilers to reduce costs and carbon emissions. Among these users is PT Pakan Sehat Unggul (PT PSU), a well-known animal feed manufacturer in Indonesia, which selected the SZL series biomass steam boiler from Wuxi ZOZEN Boiler Co., Ltd. to upgrade its steam supply system. ZOZEN’s biomass solutions have gained wide recognition for their reliability, fuel adaptability, and strong environmental performance—qualities that align well with market demand for low-carbon steam generation.

To ensure dependable performance while also helping the customer use local agricultural by-products such as palm shells, ZOZEN provided a customized 10 SZL10-1.25-SS biomass steam boiler tailored to the combustion characteristics of this fuel. The boiler adopts a horizontal double-drum structure with a longitudinal layout, paired with an advanced chain grate that ensures even fuel distribution and stable feeding. This structural arrangement reduces the risks of slag buildup and grate blockage, extending equipment longevity and improving the smoothness of operation.

In real-world use, the SZL boiler has demonstrated thermal efficiency above 86%, supported by complete combustion and low carbon residue in the ash. For PT PSU, this means reliable steam output, lower fuel consumption, and the ability to utilize readily available biomass resources, reducing dependence on fossil fuels. By connecting energy efficiency with resource availability, the project helps the enterprise enhance competitiveness while contributing to a more sustainable local industry chain.

In China, ZOZEN’s biomass solutions are equally valued by companies striving for greener development. Hubei Jinying Biotechnology—active in the health food sector—requires high-quality steam for extraction, concentration, and sterilization processes in the production of herbal pastes and enzyme products. To meet the enterprise’s strict requirements for efficiency and stability, ZOZEN recommended its SZL series biomass steam boiler, which integrates an optimized chain grate and independently controlled air chambers. This makes it easier to precisely match air distribution with fuel characteristics, ensuring thorough combustion across the grate surface.

The boiler’s dense water-cooled wall arrangement and large radiant heating area contribute to sustained high efficiency above 86%. Meanwhile, the matching flue gas treatment solution enables reduced pollutant emissions, aligning with the company’s dual goals of environmental compliance and energy saving. According to user feedback, since commissioning, the boiler has maintained highly stable operation with a strong level of automation, effectively lowering daily energy consumption and simplifying management.

From animal feed processing in Southeast Asia to health food manufacturing in China, ZOZEN’s SZL series biomass boilers have proven adaptable across multiple industries and production environments. By adjusting combustion systems, control strategies, and auxiliary configurations for different fuels—including palm shells, agricultural residues, and wood biomass—ZOZEN ensures that each solution meets the user’s process needs while maximizing the value of local renewable resources.

In recent years, ZOZEN Boiler has steadily strengthened its global presence, with projects extending across Southeast Asia, South America, Eastern Europe, and other regions. As the global energy transition continues to deepen, the company remains committed to advancing biomass boiler technology and broadening its product capabilities. With each successful installation, ZOZEN further supports industrial users in achieving cleaner, more efficient production, contributing to the growing international influence of high-quality Chinese manufacturing.
