Description
The WNS Gas-Fired Steam Boiler is a horizontal fire-tube steam boiler designed for industrial processes that require continuous steam supply. The boiler uses a three-stage heat exchange path, allowing hot flue gas to stay longer inside the heat exchange area and transfer more heat to the water side. The corrugated combustion chamber increases the heating surface area, while the heat-transfer smoke tubes support better heat exchange. The boiler also supports automatic control and dual-fuel operation. It is suitable for textile processing, garment manufacturing, food production, and production lines requiring stable gas-fired steam supply.
