Working principle of Economizer - BrainKart

The feed water which flows upward in the tubes is thus heated by the flue gases. This pre-heated water is supplied to the boiler. Advantages . 1. Feed water to the boiler is supplied at high temperature. Hence heat required in the boiler is less. Thus fuel consumption is less. 2. Thermal efficiency of the plant is …
