How does economizer affect boiler exhaust temperature?
Every 20-25°C reduction in exhaust temp increases efficiency by ~1%.
Economizer description
Function
1. Absorb the heat of low-temperature flue gas, reduce the smoke exhaust temperature, reduce smoke loss and save fuel.
2. Since the feed water is heated in the economizer before entering the drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the high-cost evaporative heating surface.
3. When the feed water temperature is raised, the wall temperature difference will be reduced and the thermal stress will be correspondingly reduced to extend the service life of the steam drum.

Application
Related Industry: Combined cycle power plant,Heat recovery steam generator(HRSG).
Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler.
