Abstract
A heat recovery system captures, stores, and releases waste heat from an exhaust. The system includes a first exchanger that removes waste heat from the exhaust and transfers it to a heat transfer fluid. A second heat exchanger transfers at least a portion of the waste heat from the heat transfer fluid to a storage device. The storage device continuously stores the waste heat until a predetermined temperature is obtained. A pump draws flow of the heat transfer fluid from the first heat exchanger to the second heat exchanger. A valve directs flow of the heat transfer fluid into the storage device during a charge mode and out of the storage device during a discharge mode.
