  • 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.Learn More

  • TYPES OF SOOT BLOWERS AND THEIR WORKING IN POWER …

    Oct 16, 2018 · In case of oil and gas fired boilers ash percentage in fuel is very less so soot deposits is very negligible. Soot blowing is required once in 10 to 12 days. Normally dry steam at 12 to 14 kg/cm2 is used as blowing medium. Soot blowers are placed in the flue gas path to clean some portion of the tube.Learn More
