ROTARY HEAT EXCHANGER FOR GAS TURBINE ASSOCIATED THEREWITH

摘要

Rotary heat exchanger for effecting thermal exchange between the inlet and exhaust gases of a gas turbine, comprising a cellular ceramic disk (1), an upstream air inlet tube (6) and a downstream inlet tube (7) on either side of the disk (1) and including friction rings (13, 14) at their ends in contact with the side surfaces of the disk. Both friction rings (13) are slit (58) so as to be applied correctly against the disk (1) despite the temperature gradients they undergo during use.
