Abstract
A rotary regenerative heat exchanger comprises a plurality of moving sector-like rotor compartments carrying regenerative heat exchange material, in which leakage of a gaseous medium having a lower pressure and being trapped by a stationary section plate in the sector-like compartments to a gaseous medium of a higher pressure is at least reduced by the provision of a means for adjusting the sector plate to such an axial clearance with respect to the end of the rotor that an intentional amount of direct leakage of the high pressure medium is maintained between the rotor end and the sector plate, giving rise to forcing out the low pressure medium from compartments that are about to leave the low pressure medium passage and replacing it with high pressure medium.
