Flue Gas - an overview | ScienceDirect Topics

The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.

See also Flue Gas Condensers that are used when water and flue gases come in direct contact with each other. How They Work. Boiler stack economizers are simply heat exchangers with hot flue gas on one side and water on the other. Or, in direct contact condensing units, the make-up water is in direct contact with the flue gases.

Flue gas system - Wärtsilä

Flue gas system . If available, flue gas from ship boilers can be used for inerting. The flue gas system washes and cools the boiler flue gas, and delivers it to the cargo tanks during cargo unloading and tank washing. As the flue gas already contains less then 5% oxygen no further treatment is necessary.

Flue Gas Recirculation: History and Uses - EnviroPower

The appeal of flue gas is that it is cheaper than steam. Flue gas is usually seen as a worthless byproduct and released into the atmosphere. It requires only a recirculation damper or fan to send a portion back to the gasifier. On the other hand, steam must be produced in a boiler using heat from the process that could be used elsewhere.
