ABSTRACT:
A fluidized bed steam generating system in which a duct is disposed between a furnace outlet and a separator inlet. The duct is formed by first and second wall panels which are comprised of a plurality of parallel tubes extending perpendicular to the direction of the flow of the combustion gases. The tubes comprising the wall panels are bent and welded to a fin extending from corresponding portions of adjacent tubes to form a gas tight structure. The ends of the tubes are connected in fluid flow communication with first and second headers which enables cooling fluid to flow through the tubes for recovering heat from the combustion gases as they flow from the furnace into the separator.
