6/1/2010 · 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.

Boiler flues are installed to send harmful gases generated by the boiler out into the atmosphere so it makes sense that they're enough of a distance away from any doors and windows that they can't re-enter the home. The regulations state that the flue must be between 30-60cm away from any parts of the home that open up, with the

How To Optimize Your Condensing Boiler System For …

The improvement in boiler efficiency can be determined by measuring the stack flue gas temperature. The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature.
