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

HEAT RECOVERY BOILERS - Thermopedia

Heat recovery boilers are also often found in association with high temperature processes such as steel and glass making. It is not uncommon for these boilers to receive additional heat by supplementary firing of other by-products or by burning gas or light oil to raise the boiler inlet gas temperature to a level commensurate with the desired

Flue Gas Heat Recovery Systems - TheGreenAge

Flue Gas Heat Recovery Systems (FGHRS) take advantage of heat within waste flue gases resulting from the combustion of gas in your boiler. This recovered heat is used to preheat the cold water entering the boiler, thereby lowering the amount of energy needed to warm the water up to the required level.

Conventional vs. Condensing Boilers | AccuServ

The heat is then transferred to cold water in pipes within the boiler via the heat exchanger, which is a tool within the boiler that transmits heat. The byproducts contain chemical elements such as CO2 and 2H20. It is how your boiler deals with the byproducts that determine whether it is classified as a conventional boiler or a condensing boiler.

Regenerators and Recuperators - Energy Solutions Center

Regenerators and recuperators are heat exchange systems that recover heat by cycling through heat sinks (regenerators) or through a high temperature metallic heat exchanger (recuperators). II Applications The heat recovered by a regenerator or recuperator is most commonly used to preheat combustion air to a furnace.
