ABSTRACT:
A high temperature fan plug for a jet heat recuperator includes inner and outer face plates spaced apart by tubular spacers extending between the plates to form a heat insulative cavity. A fastener bolt extends from one face plate through a tubular spacer and projects from the other face plate. A spring with washers at opposite ends thereof is compressed by nut members on the end of the bolt which projects from the face plate for clamping the outer and inner face plates against the spacers. A hub structure carried by the inner and outer face plates receives a seal. The face plate exposed to high temperatures in the recuperator extends between spaced apart rings that are secured to a rim that is in turn carried by the other of the face plates. The rings slidably engage the outer peripheral portion of the face plate exposed to the high temperature environment.
