Abstract
An improved fluid bed furnace is disclosed which is useful in heat treating products or particles which are to undergo a change due to exposure to high temperatures. The bed is heated by lamps effectively buried in the bed radiating energy to the fluidized particles. In one embodiment, the lamps are protected by a ceramic tube with the lamps heating the tubes which in turn heat the fluid bed.
