boiler flue gas purification measures

Flue gas measurements | Sigmahellas

Stationary gas turbines were originally developed as air craft engines and are applied to drive generators. Installations are used to generate peak load electrical power and often together with a waste heat boiler to generate heat energy. The flue gas composition is very similar to that of gas fired furnaces.
