For large-scale food processing facilities, selecting the right steam boiler configuration is essential. Instead of recommending a single boiler model, ZOZEN Boiler’s technical team analyzed the customer’s production capacity and process requirements. The plant operates two production lines capable of processing 500 tons and 1,000 tons of tomatoes per day. Based on these operating conditions, engineers proposed a combined solution consisting of an SZS series boiler and a WNS series boiler. This 35t/h & 6t/h Gas-Fired Steam Boiler configuration provides both high-capacity steam supply and flexible load management, allowing the plant to maintain efficiency under different production scenarios.

ZOZEN 35t/h & 6t/h Gas-Fired Steam Boiler

In this system, the main unit is an SZS35-1.6-Y(Q) gas-fired steam boiler. The SZS series adopts a double-drum, D-type layout that is widely used in industrial applications requiring stable and continuous steam output. This structure provides a spacious steam-water separation area, ensuring that the produced steam maintains high purity and low moisture content. For tomato paste concentration processes, such steam quality is particularly important because it supports efficient evaporation while protecting the product’s color and flavor.

The secondary unit in the 35t/h & 6t/h Gas-Fired Steam Boiler system is a 6 t/h WNS series gas-fired steam boiler. This auxiliary boiler mainly serves the 500-ton-per-day production line or operates independently during commissioning, maintenance periods, or lower production seasons. By using this flexible arrangement, the plant avoids running a large boiler under low load, which could otherwise reduce efficiency and increase fuel consumption. The 35t/h & 6t/h Gas-Fired Steam Boiler combination therefore allows the enterprise to match steam output precisely with real production demand, improving energy utilization and operational economy.

From a technical perspective, the SZS series boiler within the 35t/h & 6t/h Gas-Fired Steam Boiler configuration offers several advantages that are particularly beneficial for food processing industries. The boiler uses a full membrane water wall structure and a D-type furnace layout, providing excellent sealing and stable combustion conditions. The large furnace chamber allows fuel to burn more completely, while the optimized arrangement of heating surfaces enhances heat transfer efficiency. In addition, the boiler is equipped with an advanced low-NOx burner that helps control nitrogen oxide emissions at the source.

The WNS series boiler also contributes significantly to the overall performance of the 35t/h & 6t/h Gas-Fired Steam Boiler system. This boiler adopts a large-diameter corrugated furnace and threaded smoke tube design, which effectively increases the heat transfer area and improves combustion efficiency. The enhanced structure allows the boiler to absorb more heat from flue gases during operation. In addition, the system is equipped with a condenser installed at the rear of the boiler, which helps reduce exhaust gas temperature and further improve thermal efficiency. With these features, the WNS unit ensures that the gas-Fired Steam Boiler solution maintains high efficiency while delivering flexible steam supply.

In conclusion, the 35t/h & 6t/h Gas-Fired Steam Boiler project highlights the value of tailored steam solutions in tomato paste processing.
