    1/7/2021 · In boiler operation, heat loss to flue gases amounts to as much as 20 to 25% of the heat input. To recover heat from flue gases, economizers are generally used to preheat boiler make-up water or forced draft combustion air. The dew point usually limits the practical lower temperature of the flue gas to 300 to 350/sup 0/F.
