Rotary kiln arrangements

摘要

A rotary kiln in which reaction is to occur between counterflowing reactants and an injector for a reactant extends into a reaction zone in the kiln. The injector is provided with means for adjusting the temperature of the injected reactant to a temperature in the desired range for that zone. Further means are provided for maintaining a temperature in the desired range throughout the zone. The arrangement be used in the production of uranium oxides from uranium hexafluoride.
