  • 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.

  • Polymer or Stainless Economiser for Corrosive and Fouling

    The purpose of an economiser is to recover waste heat from a flue gas stream and use that heat to preheat boiler feed water or a process water stream. The working principle is that flue gas heat is transferred through the heat exchanger tubes of the economiser to the liquid (water or thermal oil) that is being preheated.
