  • Air preheater

    Air preheater. The air preheater uses the hot feed water to preheat the combustion air and obtain a cool water flow in the return. This cold flow can now be used in an additional economiser bundle to further reduce the flue gas temperature. This increases efficiency by 2% points, or flue gas temperatures that are roughly 40K lower.

  • Feed water preheater

    Feed water preheater. The feed water preheater is used when fuels containing sulphur are used in combination with an economiser. To prevent sulphuric acid from condensing on the economiser tubes, the feed water is heated to temperatures above the acid dew point following deaeration.

  • Why Economizer and Air Pre-Heaters are Provided in

    2009-5-3 · 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 ...
