A fluidized bed reactor is provided with heat exchange coils for controllng the temperature of the fluidized bed. The heat exchange coils are vertically oriented and elements thereof pass through the constriction plate of the reactor. Multiple function Tuyere elements are provided which admit air into the reaction chamber from the windbox, provide for passage of elements of the heat exchange coils through the constriction plate, structurally support the heat exchange coils in position and constitute thermal sleeves for accommodating differential thermal expansion of the heat exchange coils and the constriction plate. |
