This patent describes a fluidized bed furnace system wherein fuel is combusted to produce a flue gas which is passed in heat exchange relationship with a liquid to generate and superheat a vapor, comprising: a. a longitudinally elongated furnace enclosure formed of fluid-cooled tubes enclosing a furnace chamber having an open floor at the bottom thereof and a gas outlet at one end thereof. An evaporator section has a gas inlet opening to the furnace chamber and a gas outlet and an economizer section has a gas inlet opening to the evaporator section and a gas outlet, the furnace chamber, the evaporator section and the economizer arranged longitudinally in that sequence with respect to flue gas flow; and b. a support base comprising plate means having passages therethrough for admitting fluidizing air to the furnace chamber and adapted to extend across the open floor of the furnace chamber for supporting a bed of fuel material and an inert material. An air plenum is disposed immediately subadjacent the plate means for supporting the plate means and directing air through the openings in the plate means into the bed to fluidize the fuel and inert material within the furnace chamber superadjacent the plate means.
