Abstract: OPERATION OF A LEAD-IN-DEVICE RECEIVING A CONDUCTOR PASSED THROUGH THE COVER OF AN ELECTRICAL PRECIPITATION APPARATUS The invention relates to a process for operating a lead-in-device receiving a conductor which passes through the cover of an electrical precipitation apparatus down to its electrode system. A portion of the conductor is encircled by an insulator which is radially spaced therefrom and of which the upper end provides support for a structural component having the conductor gastightly passed therethrough. The space inside the insulator receives a sealing gas which is maintained under a pressure higher than that prevailing in the electrical precipitation apparatus. The sealing gas used for operating the device is a gas mixture consisting of an inert gas and at least 10 volume% of methane.

Abstract: Liquid furnace slag, more particularly liquid phosphorus furnace slag, is transformed into granules. To this end, impinging contact between a free falling stream of liquid slag and a focused stream of water maintained under a pressure between 0.5 and 1.5 atmospheres gauge is produced so as to effect break-up of the slag into particles. The resulting particles are delivered to, and complete solidification thereof is effected in, a cooling zone having water therein.
