VERFAHREN ZUM BETREIBEN EINER GASAUFKOHLUNGSANLAGE

摘要

The invention relates to a gas-carburisation unit which is provided with a heating device and which is preferably operated in the region of the soot limit and which contains a device (5) controlling the components of a carburisation gas in a reaction chamber (2) by means of a zirconium dioxide-based oxygen-measuring probe (3) exposed to the carburisation gas. To prevent the deposition of soot on the oxygen-measuring probe, a heating device (13) is provided which heats the oxygen-measuring probe (3) to a defined temperature higher than that of the reaction chamber. <IMAGE>
