  • Flue Gas Temperature and Heat in the Flue Gas Flow (Btu

    Economiser. 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%.Learn More

  • Flue Gas Condensing Temperature - HVAC-Talk: Heating, Air

    Mar 13, 2008 · As I am now dealing with a job that has Lochinvar CHHN0990 non-condensing boilers that were condensing in the boiler as well as the flue, I've done a little search and found that natural gas flue gas condenses at 60*C, which equals 140*F. Coincidentally, that is the minimum allowable return water temperature to these boilers. Return water less than 140* is no longer a problem.Learn More

  • Technical advice on boiler combustion control

    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. Learn More
