Industrial Boiler Flue Temperature

Improve The Thermal Efficiency of Industrial Boilers

The higher the exhaust gas temperature of the boiler, the greater the heat loss of the exhaust gas, so reducing the exhaust gas temperature is a good way to improve the thermal efficiency of the boiler. In order to reduce the flue gas temperature, most factories will choose to equip flue gas waste heat recovery devices, such as economizers

Gas Hot Water Boiler - Industrial Boiler Manufacturer

The biggest difference between this boiler and WNS type fuel gas boiler is that the surface is equipped with a condenser. The use of the condenser reduces the exhaust temperature of the boiler to 60-80 ° C and absorbs some of the thermal energy in the flue gas, which greatly improves the boiler's thermal efficiency, reaching more than 100.9%.
