ABSTRACT:
A method for heat treating a material such as gypsum mineral, consists in burning a fuel in a combustion bed which is in heat exchange contact through bounding walls with beds of the material to be heated. Combustion gases are passed from the combustor through the heat treatment vessels containing beds and these gases then serve to fluidize at least partly and add heat to the beds through the agency of distributors.
