Abstract (en)
The apparatus has a heating unit (10) containing a graphite felt heatable by electric heater current, through which a gas stream (G) flows, where the heating unit is arranged separately and/or in a pressure tank (21) through which the gas stream flows. Two channels carry a gas stream and are filled with the graphite felt. Contacting devices i.e. perforated disks, selectively contact the graphite felt in the channels with the electric heater current. A compressing structure causes the graphite felt to compress when the compressing structure is exposed to the gas stream. The heater current is direct, 3-phase or alternating current. An independent claim is also included for a method for cold gas spraying.
Abstract (de)
Eine Heizvorrichtung (10) zur Erwärmung eines Gasstroms (G), insbesondere einer Kaltgasspritzeinrichtung (100), wird vorgeschlagen, die einen mit einem Heizstrom erwärmbaren und mit dem Gasstrom (G) durchströmbaren Graphitfilz (11) aufweist. Auch eine entsprechende Heizeinrichtung (20), eine Anordnung (100) zum thermischen Spritzen sowie ein Verfahren (1) sind Gegenstand der Erfindung.
