Economiser Function: The function of the economiser is to extract some heat which is carried away by the flue gases up in the chimney or stack and utilize it for pre-heating the feed water supplied to the boiler. Location: It is placed in the path of the flue gases in between the exit from the boiler and entry into air preheater/chimney (Fig 30.1 and Fig 30.2).
