Flue Gas - an overview | ScienceDirect Topics

Flue Gas. Flue gases are a mixture of combustion products including water vapor, carbon dioxide, particulates, heavy metals, and acidic gases generated from direct (incineration) or indirect (gasification and pyrolysis) oxidation of RDF or intermediate syngas. From: Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2017.

Dampers and Valves | Jeremias Group - chimney systems

Dampers. Flue gas dampers (butterfly valve) are installed in the connection pipe between a boiler and the chimney and close the flue gas path, if the chimney is no longer in use. This prevents the cooling down of the heat generator and the installation room, which helps to save energy. Furthermore in the case of cascade systems, you also avoid

Fuel Ash Corrosion - The National Board of Boiler and

Any point along the flue-gas path, from combustion in the furnace to the top of the chimney, is a possible site. Any flue-gas leak can also cause this type of corrosion. The obvious locations are openings to the furnace, support penetrations through the roof, leaks around superheater, reheater and economizer penetrations, and, of course, the

Jan 24, 2016 · After these consecutive heat transfer zones the temperature of the flue gas goes down. After passing through APH flue gases pass through ESP (Electro Static Precipitator). ESP is nothing but dust /fly ash removal system. After passing through ESP flue gas goes to ID (Induced Draft) fan. ID (Induced Draft) fan suck that flue gas and throw it to the Chimney. In flue gas the amount of oxygen is …
