  • Flue-gas stack - Wikipedia

    A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler Learn More

  • Boiler Efficiency - an overview | ScienceDirect Topics

    The flue gas loss depends on the final flue gas temperature and the amount of flue gases. Thus the higher the air ratio, the higher the flue gas losses. The flue gases should leave the boiler at a temperature as low as possible to minimize the flue gas losses. Usually either economics, equipment, or corrosion issues limit the flue gas to 150 Learn More
