Abstract
A refractory constriction dome for a fluidized bed reactor is constructed to resist the upward thrust of pressure in the windbox as well as the weight of the fluidized bed. A reverse arch of refractory brick or tiles, forming the upper surface of the dome, is the structural feature which functions to resist upward thrust.
