Abstract
A sector plate static sealing arrangement for a rotary regenerative air preheater employs a single rib attached to and extending along the center line of the sector plate toward the air preheater casing. The rib cooperates with a static seal attached to the casing to provide both the sealing and positioning functions. Braces for the rib provide support and form a sloped surface which reduces ash accumulation.
