what is the function of economizer in steam boiler

Importance & Use of Economiser in Thermal Power …

Economizer performs a key function in providing high overall boiler thermal efficiency by recovering low level energy from the flue gas before it is exhausted to the atmosphere. Economizer recovers the energy by heating the boiler feed water. When the water is boiled in steam boiler, the steam is produced which is then super-heated after

Why Economizer and Air Pre-Heaters are Provided in …

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
