Innovative New Chimney Design for Wet Flue Gas

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
