ABSTRACT:
The invention describes a method and a means for supplying nozzles comprising concentric pipes with gaseous and/or liquid hydrocarbons in which oxygen or oxygen-containing gases are simultaneously introduced into a converter. In so doing, the gases and/or liquid hydrocarbons are conducted through collecting pipes leading into distribution chambers. They are conducted from the distribution chambers through hydrocarbon volume control devices, which are integrally arranged along with the hydrocarbon distribution devices in a rotatable device element of the rotatable control unit, on to nozzle pipes. Then, the gaseous hydrocarbons are further conducted through a safety control member arranged downstream from the hydrocarbon volume control device. Thus, the even supply of gaseous and/or liquid hydrocarbons to the nozzles is ensured at highly varying throughput rates and alternate supply, in a manner which is simple and reliable.
