| 摘要 |
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. |
