Abstract
A fluidized bed process heater with a reaction chamber of toroidal configuration is provided with radially-oriented bed coils in the reaction chamber in which steam is generated or other process fluids are heated. The inner wall of the toroidal reaction chamber is water-cooled and the bed coils in the reaction chamber are removable. The return bends of the coils are protected against erosion from particulate bed solids.
