Process and apparatus for supplying a kroll reactor with zirconium tetrachloride vapour
 The invention relates to a process and apparatus for the supply of a Kroll reactor with zirconium tetrachloride vapor, in which zirconium chloride powder is vaporized in a sublimator by heating power and the vapor obtained is passed into the reactor. Part of the heating power applied in the sublimator is supplied to the powder by an internal heating means, and the remainder of the heating power is supplied to the wall of the sublimator by an external heating means. The heating power of the internal heating means is used for the sublimation of the zirconium tetrachloride powder and the heating power of the external means is applied in order to compensate the heat losses of the wall of the sublimator. The apparatus for application of the method includes a means for measuring the wall temperature of the sublimator and a regulator sensitive to the variation of this temperature with respect to a nominal temperature and which is capable of modifying the power applied to the external and internal heating means, with the total power remaining constant for a fixed vapor flow rate.
