The production processes of textiles such as drying, shaping, printing, etc require stable heat source support. WNS series gas-fired steam boilers feature fully automatic and safe operation to ensure the stability of the heat source during the production process. At the same time, the gas-fired boiler has remarkable energy-saving and environmental protection effects, the thermal efficiency can reach over 98%, and the NOx emission can be as low as 30 mg/m³, which fully meets the needs of the environmental protection era.
