摘要： The invention relates to a hot-blast lance for use in metallurgical processes, such as for example steel production, with which hot air can be blown in above a molten bath of a steel converter, which consists of an outer shell and at least one inner shell, and at least one intermediate space or cooling channel through which coolant flows is arranged between the outer shell and an inner shell. In order to achieve the effect here that a hot-blast lance can be further developed to the extent that hot air can be introduced into a reaction vessel, for example a steel converter, particularly effectively, that is to say with least possible thermal losses, and the lance is adapted better to this operating environment, it is proposed according to the invention that the inner shell (2) or the innermost shell (4) at least partially consists of a thermally insulating further shell (4), or a thermally insulating shell, or is provided with such a shell, or is coated with a thermally insulating layer.

摘要： The invention relates to a method for operating a blower lance arrangement, in which method hot blast is blown onto the melt bath and/or the bulk material bed in a converter, wherein the hot blast lance is fed via a hot blast line from a hot blast source, according to the preamble of claims 1 and 8. In order to achieve a more effective blowing method and to improve the blower lance in terms of the coupling with the hot blast source, according to the invention the hot blast lance is detachably connected to the hot blast source in such a manner that the connection can be automatically detached and reconnected for each batch, i.e. between the batches.

摘要： The invention relates to a method for operating a regenerator (1) for generating hot blast air for a steelmaking or steel treatment process, or a chemical process, wherein cold gas and hot gas is cyclically guided through a bulk material located in an annular space (4) between a hot grid (2) and a cold grid (3) surrounding the hot grid (2), and wherein a quantity of bulk material is removed from the annular space (4) in recurring cycles. The invention further relates to a regenerator. In order to achieve that on the one hand, the bulk material expanding during the hot phase does not deform and/or destroy the cold grid (3), and on the other hand, the bulk material particles do not get further eroded under alternating thermal stress, according to the invention during the phase of the cold gas application, or shortly before, or shortly thereafter, a defined quantity of bulk material determined by measuring means (20) is discharged from the bulk material through floor openings of the annular space (4).
