Abstract

An economical heat recovery system [100] is described for use in a boiler [26] includes an air preheater [150] that receives hot flue gasses [FG1] and inlet air and creates heated air [A2] and incremental air [A2']. The incremental air [A2'] is provided to a regenerative heat capture and transfer (RHCT) system [300] positioned to receive the incremental air [A2'] from the air preheater [150]. The RHCT includes a heat exchanger [310] that preheats feed water [WF1] for the boiler [26]. Since a heat exchanger [310] receives clean air as opposed to those of the prior are, it may be made more efficient with more heat exchange units in closer proximity, since there is little chance of blockage. Also, there is less maintenance with the present invention.
