  • Patent number: 8955466
    Abstract: A system providing for heat recovery from exhausted flue gas in a steam generator is described comprising a flue gas outlet conduit defining a flow path for flue gas from a flue gas outlet of a steam generator to a flue gas conduit junction point; a flue gas primary conduit defining a flow path for flue gas from the junction to a primary air preheater; a flue gas secondary conduit defining a flow path for flue gas from the junction to a secondary air preheater; wherein a steam generator process fluid heat exchanger is disposed within the flow path of the flue gas primary conduit upstream of the primary air preheater to recover some heat from the flue gas in advance of the primary air preheater. A method implementing the flow principles embodied in such a system is also described.
