Abstract: A regenerative heat exchanger for the heat exchange of gaseous media with a substantially cylindrical heat storage body including a radial seal for use in a regenerative heat exchanger and a method for separating gaseous media in a regenerative heat exchanger. The heat storage body of the regenerative heat exchanger may include a plurality of radially extending sector walls which subdivide the heat storage body into sectors. At least two heat storage chambers which are arranged behind one another in the radial direction are provided within a sector, which heat storage chambers are arranged for the through-flow of gaseous media.

Abstract: The invention relates to a method for temperature-dependent setting of a sealing gap between an adjustable seal and a revolving rotor of a regenerative heat exchanger by means of at least one actuating apparatus which comprises at least one rod body which is thermally influenced in an alternating manner and whose temperature-dependent change in axial length is converted into an actuating movement for the seal. It is provided in accordance with the invention that this rod bod is arranged at least in sections in a chamber and a control medium flows through or about this chamber at least in part, which medium acts in a direct or indirect manner in a thermally alternating fashion on said rod body, with the temperature level of the control medium corresponding to a temperature level of a gas volume flow flowing through the rotor, so that a change in axial length of this rod body is produced depending on a temperature change of this gas volume flow and a respective actuating movement for the seal is brought about.

Abstract: A regenerative heat exchanger, including a rotor mounted so it is rotatable, which has at least one first gas volume flow to be heated and at least one second gas volume flow to be cooled flowing through it, as well as a method for operating the regenerative heat exchanger, is provided. The inflowing first gas volume flow enters the rotor at a first front side of the rotor and exits the rotor again at a second front side of the rotor at an outflowing first gas volume flow. To increase the heating performance, a leakage volume flow is captured at the first front side of the rotor and supplied to the inflowing first gas volume flow and/or a leakage volume flow is captured at the second front side of the rotor and supplied to the outflowing first gas volume flow.

Abstract: The invention relates to a regenerative heat exchanger for the heat exchange of gaseous media with a substantially cylindrical heat storage body. The invention further relates to a radial seal for use in a regenerative heat exchanger and a method for separating gaseous media in a regenerative heat exchanger. The heat storage body of the regenerative heat exchanger comprises a plurality of radially extending sector walls which subdivide the heat storage body into sectors. At least two heat storage chambers which are arranged behind one another in the radial direction are provided within a sector, which heat storage chambers are arranged for the through-flow of gaseous media.
