Dairy processing relies heavily on saturated steam for concentration, sterilization, evaporation, and drying. Any fluctuation in steam pressure or output can directly affect product quality, hygiene standards, and production continuity. After a comprehensive technical evaluation, ZOZEN Boiler deployed two sets of 6 TPH Condensing Gas-Fired Steam Boiler units to support the upgraded dairy processing lines, providing a solid foundation for stable and efficient production.

The newly installed 6 TPH Condensing Gas-Fired Steam Boiler units now serve core processes including milk protein concentrate, lactose, and cream production. Compared with the original biomass-fired boilers, the gas-fired solution delivers cleaner combustion, reduced fuel handling complexity, and more consistent thermal output, which is essential for food-grade production environments.

ZOZEN 6 TPH Condensing Gas-Fired Steam Boiler

Technical Overview: WNS Series Condensing Gas-Fired Steam Boiler

The 6 TPH Condensing Gas-Fired Steam Boiler supplied for this project adopts ZOZEN’s mature WNS series design. It features a horizontal internal-combustion wet-back structure combined with a three-pass flue gas path, ensuring sufficient heat transfer area and stable long-term operation. This structure helps maintain uniform furnace temperature distribution and reduces thermal stress on pressure components.

Key technical characteristics of the 6 TPH Condensing Gas-Fired Steam Boiler include optimized furnace geometry for natural gas combustion, high-efficiency threaded smoke tubes, and an integrated condensing heat recovery system. By recovering both sensible heat and latent heat from flue gas, the boiler significantly improves overall fuel utilization and lowers exhaust heat loss.

In addition, the boiler is equipped with a fully automatic control system, precise pressure regulation, and comprehensive safety interlocks covering ignition, combustion, water level, and pressure protection. These features enable stable, unattended operation and reduce operator workload, making the 6 TPH Condensing Gas-Fired Steam Boiler particularly suitable for continuous-operation dairy processing plants.
