摘要： A shaft furnace, in particular a blast furnace, includes a metal jacket defining the furnace outer wall and a protective layer protecting the inner surface of the outer wall. At least one condition monitoring probe is arranged inside within the protective layer to monitor the latter. The condition monitoring probe is connected to a wireless module arranged outside the outer wall to transmit condition monitoring data. The wireless module is located inside a casing mounted to the outer surface of the metal jacket. The condition monitoring probe includes one or more conductive loops positioned at predetermined depths below the front face of the cooling plate body, or of the refractory lining, so that wear of the body, resp. refractory, can be detected by a change of an electrical characteristic of the loop(s) due to abrasion.

摘要： A fluid cooled housing system for use in metal making furnaces. In particular, the present invention related to a novel and inventive housing and guard member configured to receive and protect an implement, such as a burner or a lance, used in connection with metal making furnaces. A preferred embodiment of the present invention comprises a housing comprising an outer shell and an inner shell that define a fluid chamber, an end cap, a bushing insert, a face plate, a fluid inlet, and a fluid outlet. Both the fluid inlet and the fluid outlet are preferably in fluid communication with both the fluid chamber defined by the shells and a fluid chamber defined by the bushing insert. In alternative preferred embodiments, the housing system further comprises a guard member that preferably envelopes and further protects the fluid cooled housing.

摘要： Disclosed are apparatus and method for preparing carbon black, in which the carbon black may be continuously formed and activated. In one embodiment, carbon black powders formed in a combustion reactor are converted into a slurry which in turn is refluxed to the combustion reactor in a repeated manner, thereby to allow successive activation treatments. In this way, a sufficient residence time for the activation of the carbon black may be secured.
