Boiler with economizer
WebJul 12, 2024 · Boiler economizers contain safety valves for their safe and smooth functioning. Working of the Economizer in a Steam Boiler: Flue gases enter the economizer as they exit from the steam boiler. With its finned tubes, the economizer takes over the heat of the flue gases and transfers it to the feed water. WebA feedwater economizer is appropriate when insufficient heat transfer surface exists within the boiler to remove combustion heat. Boilers that exceed 100 boiler horse-power, …
