ABSTRACT:
An apparatus for heat recovery from an exhaust gas with waste heat from a heat machinery unit, which comprises a pair of first and second chemical heat-storing units, each comprising a vessel containing a reactant material capable of releasing a reaction-susceptible material upon heating with an exhaust gas and emitting the heat of reaction upon combination with the reaction-susceptible material and a heat exchanger piping provided in the vessel and through which a heat transfer medium is passed. The high temperature gas from the heat machinery unit is applied to the vessel in one of the first and second chemical heat-storing units, thereby resulting in a reaction for leasing the reaction-susceptible material. A further reaction to combine the heat-susceptible material in the vessel in the other of the first or second chemical heat-storing units, and is passed the heat transfer medium through the heat exchanger piping in the vessel in the other of the first or second chemical heat-storing unit for continuously providing a high heat recovery efficiency.
