ABSTRACT:
A regenerative air preheater is disclosed comprising a heat exchanger including a power operated rotary heat exchanging unit and a surrounding stationary casing having opposite inlets and outlets for combustion air and flue gas defining two axial passageways for combustion air and flue gas, respectively, through the rotary heat exchanging unit, each such passageway being connected with its inlet and outlet in a duct for conveying a flow of combustion air or flue gas, respectively, through the heat exchanger, means being provided to conduct away from the flue gas outlet of the heat exchanger at least a major portion of any air passing from the combustion air passageway to the flue gas passageway during operation of the heat exchanger, and a branch duct being connected to the flue gas duct at a point located after the heat exchanger, as viewed in the direction of flow of flue gas through the flue gas duct, in order to allow flue gas to be drawn off from the flue gas duct for subsequent use as an inert gas.
