Abstract
A fluidized bed combustion system in which a duct connects a reactor and a separator and extends within the furnace section of the reactor. The duct is wedge shaped, having an inlet width greater than its outlet width, and the bottom wall of the duct angles upwardly from the outer side wall of the duct. A portion of the duct extending within the furnace section is formed by cooling tubes which also form a portion of a side wall of the reactor, and a portion of the duct extending outside the furnace section is formed by cooling tubes which also form a portion of an outer wall of the separator. The portion of the duct extending within the furnace section is secured to the portion of the duct extending outside the furnace section to connect the reactor and separator without the use of expansion joints or seals.
