Abstract
Rotary regenerative heat exchange apparatus in which a rotor of heat absorbent material is alternately exposed to a heating fluid and to a fluid to be heated. The rotor is surrounded by a housing having a sector plate at opposite ends thereof adapted to separate the heating fluid from the fluid to be heated. The apparatus is provided with control means that intermittently drives a sector plate into a sealing relationship with the adjacent edge of the rotor after which a predetermined reference point on the rotor activates a sensor to move the sector plate away from the rotor to permit freedom of movement therebetween.
