Abstract
A method of heat treating a material, particularly for the despersion and firing of wet agglomerates, slurries, sludges and the like in fluidized bed, spouting bed or spouting/fluidised bed combustors, comprises extracting hot sold particles from the bed of the combustor, mixing the hot particles and the material in a mixing chamber, and conveying at least part of the product of the admixture to the combustor. Apparatus is also provided for heat treatment of a material by this method.
Claims19

- a. removing hot solid particles from the bed of a particle bed combustor;
- b. mixing the removed hot bed particles and said material in a mixing chamber;
- and
- c. conveying at least part of the product of the admixture to the combustor.
Apparatus for heat treatment of a material which comprises:
- a mixing chamber;
- a particle bed combustor;
- means to remove hot solid bed particles from said particle bed combustor and convey them to said mixing chamber;
- means to supply the material to said mixing chamber;
- and
- means to convey at least part of the product of the admixture from the mixing chamber to the combustor.
