Abstract: Flue gases waste heat recovery of coal-fired power plants is associated with lowering their temperature to values significantly above the dew point, because acid deposition leads to corrosion of the affected heating surfaces. When wet gas cleaning technologies are used, additional heat is lost to heat the purified gases with hot air before they enter the stack. The proposed innovative method provides for a more complete use of thermal energy of exhaust gases and eliminates the need for additional reheating of the wet gases before entering the stack. This can be achieved by directing a portion of the gas stream to a bag filter in which there is slight reduction of the flue gas temperature and then mixing this portion with the main stream passing via the economizer or air preheater in a pre-existing mixing chamber to achieve the desired humidity and temperature of flue gases. A technical and economic assessment of the expediency of utilizing the waste heat from the flue gases by means o
