Maximum Temperature Of Flue Gas From Boiler

An Alternate Approach to Flue Gas Heat Recovery

2016-11-2·Because of the ash, sand and char in the flue gas, a re-cuperative (usually tubular) air heater is the norm. The air heater typically is the last boiler heat trap. Once the com-bustion air temperature requirements are met, additional air heater surface is used to minimize the stack temperature. As the flue gas temperature approaches the air

Technical advice on boiler combustion control

2 ·The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result, the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra oxygen reached this temperature by receiving fuel energy in other words, fuel was purchased to heat the extra oxygen.
