What should I consider when selecting a 10 ton gas-fired steam boiler for 1.25 MPa working pressure?

A 10 ton gas-fired steam boiler with a working pressure of 1.25 MPa is commonly used in food processing, textile production, chemical manufacturing, pharmaceutical plants, laundries, and other facilities that require a continuous steam supply. For this application, the ZOZEN WNS10-1.25-Y(Q) gas-fired steam boiler is a suitable configuration to consider.

The WNS10-1.25-Y(Q) is a horizontal fire-tube steam boiler designed for oil or gas firing. Its rated evaporation capacity is 10 t/h, and its working pressure is 1.25 MPa. The boiler can be equipped with a natural gas burner, while other gaseous or liquid fuels may be considered according to the project conditions. The final burner configuration should match the fuel composition, gas pressure, local emission requirements, and electrical standards.

One important feature of the WNS boiler is its three-pass heat-transfer arrangement. The flame and flue gas travel through the furnace and tube banks before entering the stack. This increases the heat-transfer path and supports efficient fuel utilization. The corrugated furnace design provides space for thermal expansion, while the wet-back structure helps reduce the thermal load on the rear tube sheet and supports stable operation.

For a 10 t/h steam boiler, the auxiliary equipment is also important. A complete ZOZEN boiler system may include a burner, feedwater pump, water treatment system, control cabinet, safety valves, economizer, chimney, deaerator, blowdown system, and fuel train. The equipment combination can be adjusted according to the customer’s plant layout and steam process. If the customer only needs the boiler body, ZOZEN can also prepare a boiler-only quotation.

Automatic control is another practical consideration. The control system can monitor operating pressure, water level, burner status, feedwater conditions, and safety interlocks. These functions reduce manual intervention and help operators manage the boiler according to the steam demand. The final control design should comply with the applicable local regulations.

The quotation for the WNS10-1.25-Y(Q) should normally include the boiler technical specification, burner information, auxiliary equipment list, foundation requirements, installation scope, delivery terms, and spare parts recommendation. To prepare an accurate quotation, the project team should confirm the natural gas composition, gas pressure, power supply, steam temperature, feedwater temperature, emission standard, installation altitude, and whether a complete boiler room system is required.

ZOZEN has more than 20 years of overseas market experience. Its industrial boilers are supplied to more than 100 countries and regions, with support covering system design, manufacturing, delivery, installation guidance, commissioning, and after-sales service. For this application, the WNS10-1.25-Y(Q) offers a compact steam-boiler solution with automatic operation and configuration flexibility.
