Why Economizer and Air Pre-Heaters are Provided in Boilers

Boilers are provided with economizer and air pre-heaters to recover heat from the flue gases. Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters. If economizer alone is provided then the efficiency will be lower by 12 % when compared to
