Working principle

WNS type low nitrogen condensing gas boiler aims at the key technical factors such as the relationship between water vapor condensation rate in flue gas and exhaust gas temperature, the relationship between condensation rate and thermal efficiency, and the corrosion rate of condensate water to different steel grades. Through reasonable design of heating surface, the exhaust gas temperature is reduced to ensure the condensation rate of water vapor in flue gas to meet the design requirements, so as to greatly improve the thermal efficiency of the boiler.
