Abstract

An apparatus for the thermal removal of lacquer and like coating materials from metal and ceramic objects comprises a fluidized-bed retort which is partly heated by a burner in a burner chamber formed in a unitary housing with the retort. Combustibles in the retort gases are recycled to an afterburner chamber for combustion to provide additional heating for the retort. The bottom of the retort is surrounded by an annular gap through which the afterburner gases pass and then to an outlet connected to the afterburner chamber by a valve.
