heat that fly with the flue gases are utilized to generate power with the aid of Economizers. The Economizers and its accessories like Super heaters and Reheaters absorb their heat for conversion. This could be possible only if the velocity over the economizer remains uniform and it lies as the objective of the case.
Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler. It is simply a heat ex-changer with hot flue gas on shell side and water on tube side with extended heating surface like Fins or Gills.

They are the sane as the super heaters but as their exit temperature is a little bit less than super heaters and their pressure is 20% -25% less than the super heater, they can stand less quality material alloys. Application: Steam super heater is consisted of dense tube coils and is placed in the flue under the tempearture 450ºC-1000ºC.
Economizers and air heaters require a greater heat transfer surface per unit of heat recovered than water-cooled walls, superheaters and reheaters; this is mainly due to the relatively small temperature difference between the flue gas and the feedwater or the combustion air.
Application: Alloy Steel Tubes (Pipes) are High-pressure Boiler Tubes, which are mainly applied on Super Heaters, Reheaters, Water Walls, Economizers of the Super Critical and Ultra Super Critical Boilers, the Alloy Tubes required to have high creep rupture strength.
