A Food manufacturer recently partnered with ZOZEN Boiler to upgrade its steam supply system for protein powder processing. To meet the plant’s dual needs—high-temperature steam and efficient utilization of biogas generated during production—ZOZEN provided a customized Biogas and Natural Gas Superheated Steam Boiler solution. The selected unit, an SZS-series 25 tph superheated steam boiler, is engineered to handle co-firing of biogas and natural gas while maintaining stable, reliable steam output essential for food-grade manufacturing. 

At the technical level, the Biogas and Natural Gas Superheated Steam Boiler demonstrates a combination of advanced combustion technology and a well-designed water-tube structure. Co-firing biogas with natural gas requires a burner capable of precise mixing, stable ignition, and controlled combustion. To address this, ZOZEN equips the boiler with an American Zeeco ultra-low-nitrogen burner, known internationally for its accuracy and reliable flame control. This configuration ensures that the boiler maintains stable operation even when fuel composition fluctuates—an important consideration when using production-generated biogas.

ZOZEN Biogas and Natural Gas Superheated Steam Boiler

The furnace and convection section of the Biogas and Natural Gas Superheated Steam Boiler are optimized to achieve smooth heat absorption and maintain the required superheated steam temperature. Its D-type water-tube design offers rapid heat transfer, fast steam generation, and excellent load adaptability, all essential for continuous food-industry production lines. A fully sealed membrane-wall structure enhances system tightness, reduces heat loss, and improves overall operational efficiency.

During co-firing, emission control is a key requirement for food enterprises that prioritize clean production. The burner’s ultra-low-NOx design, combined with ZOZEN’s precise air-fuel ratio control system, helps the Biogas and Natural Gas Superheated Steam Boiler maintain clean and compliant operation. These features support environmentally conscious production while ensuring high-temperature steam remains steady and reliable.

ZOZEN’s strength is not only in boiler manufacturing, but also in its ability to design solutions around real production needs. Before finalizing the system, ZOZEN’s technical team evaluates the customer’s steam quality requirements, biogas output, fuel supply conditions, and operational schedule. The result is a Biogas and Natural Gas Superheated Steam Boiler configuration tailored to the client’s process and performance expectations. For Sinoglory, this ensured that the boiler would integrate smoothly into the existing plant while improving overall energy utilization.

Beyond technology, ZOZEN Boiler is recognized for comprehensive after-sales support. From installation guidance and commissioning to operator training and remote service, the company ensures that each Biogas and Natural Gas Superheated Steam Boiler continues to operate safely and efficiently long after delivery. This service system is especially valued by food manufacturers, who depend on stable steam supply and fast technical response to protect product quality.

Through this project, ZOZEN once again demonstrated its capability to provide professional, reliable, and clean energy solutions for the food industry. The Biogas and Natural Gas Superheated Steam Boiler not only meets Sinoglory’s immediate production needs but also enhances long-term sustainability by transforming by-product biogas into valuable thermal energy.
