    The clean gas enters saturated with moisture at 45 - 50°C and is re-heated to typically 75 - 90°C to give the outlet gas the buoyancy required to lift it through the chimney. The flue gas at this stage typically contain fly ash, condensing acid, water with a high chlorine content, unbleacted limestone, remnants of SO2 and SO3 etc.

  • Innovative New Chimney Design for Wet Flue Gas - Hadek

    Innovative New Chimney Design for Wet Flue Gas - Hadek

    Usually older chimneys were designed with high flue gas velocities, to facilitate dispersion. These velocities are too high for flue gases running at or below the water dew point since condensate will be carried out of the chimney. By using the extra space provided in the annular space, the chimney diameter is increased and consequently the

    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 .

    May 19, 2010 · I'd like people's opinions on what the minimum design velocity of flue gas should be from the gas stack. In the past I have used numbers between 50 and 60ft/s. I did a search online and saw a minimum of 16ft/s. I checked B&W Steam and it said that the 'typical' was 30-35ft/s. Also, are there any serious issues with the low gas velocity?
