摘要：A heat recovery apparatus for boilers, or the like, comprising a heat recoveryhousing having a gas inlet and a gas outlet disposed within the bottom and the top,respectively. A plurality of interconnected water conduit tubes is provided. A plurality ofby-pass dampers pivotally connect between the pair of end walls within the heat
recovery housing such that when the by-pass dampers are in a closed position, the closedby-pass dampers define a generally flat by-pass structure angularly disposed withrespect to the horizontal plane. A plurality of exit dampers is pivotally connectedbetween the pair of end walls such that when the exit dampers are in a closed position,the closed exit dampers define a generally horizontal flat exit structure extendingbetween the pair of end walls. The process for recovering heat from hot combustiongases flowing through the combustion gas inlet comprises closing pivotally the by-passdampers which essentially simultaneously divert or change the direction of flow of thehot combustion gases towards the water conduit tubes in order to effect a heat transferbetween the hot gases and the water passing circuitously through the conduit tubes andextract condensate from the hot gases which accumulates in the bottom of the heatrecovery housing. The process additionally includes opening pivotally the exit dampers to
allow the passage of gases from the water conduit tubes to the combustion gas outlet,and draining accumulated condensate from the bottom of the heat recovery housingthrough a condensate drain.
