Patent ID: 8590904

Claim:
A seal for use in high temperature environments of a boiler assembly to remedy cracks and air leaks, said seal comprising: a high temperature silicone adhesive sealant layer; a first non-ceramic layer of high density fibers mounted to said silicone adhesive sealant layer; a first expanded metal layer mounted to said first non-ceramic layer; a first silicone cloth layer mounted to said first expanded metal layer; a metal reinforcement layer mounted to said first silicone cloth layer to provide structural integrity without the use of ceramic materials; a second expanded metal layer mounted to said metal reinforcement layer; a second non-ceramic layer of high density fibers mounted to said second expanded metal layer; a turbine mesh layer mounted to said second non-ceramic layer; a second silicone cloth layer mounted to said turbine mesh layer; a sealing castable applied over said second silicone cloth layer to provide a covering; and a high temperature bonding adhesive disposed between each layer following said first non-ceramic layer to bind the layers together.
