Industrial Boiler Flue Temperature

Boiler Combustion | CleanBoiler.org

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature …

Determination of Industrial Boiler Temperature Profile for

flue gas inlet temperature if the superheater lies directly behind the screen tubes, however, if not, boiler bank tubes upstream of the superheater if any would have an effect on the temperature by reducing its value. A temperature downstream of the boiler bank tubes has to be calculated to obtain the flue gas temperature in this case. 3.

Back to Basics: Venting for Gas-Fired Boilers | Liming

Jun 04, 2003 · As the efficiency of a boiler goes up, the temperature of the flue gases go down, and the gases are more likely to condense in the flue. When combustion efficiency exceeds approximately 83%, there is a good possibility that the flue products will condense.

Flue gas temperature or flue gas loss | Bosch steam boiler

The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
