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.

A heat exchanger does precisely what its name describes - it allows heat to be exchanged between two fluids or substances, usually water or gas, without letting the substances mix together. Within the heat exchanger is a long, coiled pipe. This pipe is surrounded by a substance that can be heated, such as cold water.
