ABSTRACT:
Control of the seal of a rotary regenerative air preheater is provided by a plurality of inductance sensors (S1-S8) arranged around the path of travel of seal parts borne by the rotating part of the preheater. When these are sealing frames borne on hoods of a stationary matrix type preheater (12) drive means such as magnetic actuators (5) are fed power signals through slip rings (4). When they are seal strips on a rotating matrix type, the drive means are mounted on the sector plates of the stationary body. A control circuit compares the signals received sequentially from the sensors and drives appropriate one or ones of the drive means to bring the sealing means to a predetermined axial relationship, or to hold them there. The sensors may be paired with comparison sensors in the same environment whereby to reduce errors due to changes in temperature etc.
