Abstract
An insulation system for protecting metal membranes that seal a fluidization grid floor in a process vessel to the vessel wall or to a standpipe in the vessel. The seal is comprised of erosion-resistant castable refractory, compressible insulation and metal in specifically arranged layers and in a manner such that expansion of the grid floor does not stress the castable refractory.
