    8/7/2021 · Think about it; the boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy leaves with the flue gas. On the other hand, the boiler system takes in cold water, heats Learn More

  • Diesel Exhaust Gas

    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
