Economizer - an overview | ScienceDirect Topics

For every 20 °C that the flue gas is cooled by the economizer or air heater, the overall boiler efficiency increases by approximately 1%. The economizers recover the energy by heating the boiler feedwater while the air heaters preheat the combustion air. Coal combustion is enhanced and coal ignition becomes stable when the air is heated before

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
