Abstract
A collection element arrangement is provided having sleeve attachments near their lowermost ends which simulate a continuous sloping surface, or floor. The sleeve attachments upper surfaces forming the floor permit collected solids to flow down the sloping surface back into the furnace or reactor chamber. Stainless steel can be used for the collection elements and sleeve attachments since the floating floor accommodates differential thermal expansion between CFB components.
Claims10
An impact-type separator for a circulating fluidized bed reactor, the separator comprising:
- a spaced apart array of collection elements depending from a roof of the circulating fluidized bed reactor;
- and
- a plurality of sleeve attachments, one attachment surrounding the lower end of each of the collection elements in the array, each attachment having a substantially planar upper surface connected to the collection element, the upper surfaces of the plurality of sleeve attachments cooperating with each other to form a floor around the collection elements in the array, wherein the individual collection elements may expand from heating independently of and without interference from other collection elements or circulating fluidized bed components and by-products.
