A technique for recovering heat from a high temperature effluent stream from catalyst regeneration or the like, comprising processes and means for: (a) passing the effluent stream in heat exchange relationship in a steam generator with boiler feed water to produce high pressure steam and partially cool the effluent stream; (b) passing the partially cooled effluent stream from the steam regenerator in heat exchange relationship to preheat high pressure boiler feed water and further cool the effluent stream; and (c) passing the preheated boiler feed water to the steam generator. The apparatus and processes for thermal energy recovery may be used to treat hot regenerator effluent from FCC or OTO-type processes, thereby producing a cooled flue gas stream to discharge to ambient atmosphere.

A communication passage in a Stirling cycle transducer includes a cylindrical shaped thermal regenerator providing flow paths aligned with a regenerator cylindrical axis for providing periodic gas flow between first and second interfaces of the regenerator. A first heat exchanger conveys gas between a periphery of the heat exchanger and the first interface causing a change of direction of gas flow between radially and axially oriented flow within the regenerator and transfers heat between the gas and an external environment in a direction aligned with the regenerator cylindrical axis. A second heat exchanger conveys gas between a periphery of the heat exchanger and the second interface causing a change of direction of gas flow between radially and axially oriented flow within the regenerator and transfers heat between the external environment and the gas in a direction aligned with the regenerator cylindrical axis.

The thermal regenerator is operable to alternatively receive thermal energy from gas flowing in a first direction through the regenerator and to deliver the thermal energy to gas flowing in a direction opposite to the first direction through the regenerator. The compression chamber, the expansion chamber, and the regenerator together define a working volume for containing a pressurized working gas. Each of the first and second interfaces are configured for reciprocating motion in a direction aligned with a transducer axis, the reciprocating motion being operable to cause a periodic exchange of working gas between the expansion and the compression chambers. In one aspect, at least one of the first and second interfaces includes a resilient diaphragm, and a cylindrical tube spring coupled between the diaphragm and the housing, the tube spring being configured to elastically deform in a direction generally aligned with the transducer axis in response to forces imparted on the tube spring by the diaphragm to cause the at least one of the first and second interfaces to have a desired natural frequency. In another aspect the apparatus includes a first heat exchanger in communication with the expansion chamber, a second heat exchanger in communication with the compression chamber, the thermal regenerator is disposed between the first and second heat exchangers, and each of the first and second heat exchangers are peripherally disposed within the housing with respect to the transducer axis and configured to receive working gas flowing to or from the respective chambers and to redirect the working gas flow through the regenerator.

The invention relates to a method for reducing the axial heat conduction of a regenerator cold storage material by a regenerative low temperature refrigerator. In this method, when filling the cold storage material of the regenerator of the refrigerator, the thermal barrier made of the heat insulating material is put into the regenerator cylinder according to a certain interval distance, and the cold storage material of the regenerator is divided into several sections that are thermally disconnected. There are even and densely distributed small holes in the middle of the blocker, which does not affect the reciprocating flow of the working medium in the regenerator, and the small holes are arranged locally and regularly, which is beneficial to the heat exchange between the working medium and the cold storage material. The thermal resistance of the thermal isolator is more than 40 times that of the thermal storage material of the same thickness of the regenerator, but it has little effect on the thermal efficiency of the regenerator. The invention effectively reduces the axial heat conduction of the regenerator of the refrigerator, and the directional flow path of the working medium gas is unobstructed without gas retention, thereby improving the effective cooling capacity and efficiency of the refrigerator. This method can be applied to various regenerative cryogenic refrigerators.
