摘要： A processor of a sensor device receives a plurality of images capturing a scene that depicts at least a portion of a conveyer entering a treatment area of a food processing system. The processor processes one or more images, among the plurality of images, to detect one or more characteristics in the scene. Processing the one or more images includes detecting presence or absence of a product on the at least the portion of the conveyor depicted in the scene, and classifying the scene as having one or more characteristics among a predetermined set of characteristics. The sensor device provides characteristics information indicating the one or more characteristics detected in the scene to a controller. The characteristics information is to be used by the controller to control operation of one or both of the conveyor and the treatment area of the food processing system.

摘要： A method of operating a BOF bottom stir tuyere having an inner nozzle surrounded by an annular nozzle, including during a hot metal pour phase and a blow phase, flowing an inert gas through both nozzles; during a tap phase, initiating a flow of a first reactant through the inner nozzle and a flow of a second reactant through the annular nozzle, and ceasing the flow of inert gas through the nozzles, wherein the first and second reactants includes fuel and oxidant, respectively, or vice-versa, such that a flame forms as the fuel and oxidant exit the tuyere; during a slag splash phase, continuing the flows of fuel and oxidant to maintain the flame; and after ending the slag splash phase and commencement of another hot metal pour phase, initiating a flow of inert gas through both nozzles and ceasing the flows of the first and second reactants.

摘要： An oxy-gaseous fuel burner (400, 500) or a solid fuel burner (700) having an annular cavity (404, 504, 704) upstream from and proximate to an outlet plane (416, 516, 716) and a converging (434, 734) or converging-diverging nozzle (537) located upstream from and proximal to the cavity (404, 504, 704). The solid fuel burner (700) also is preferably operated so that the velocity of gas exiting a second annulus (730) is less than the velocity of gas exiting a central conduit (710).

摘要： A control scheme for a furnace can use real-time and historical data to model performance and determine relationships between different data and performance parameters for use in correcting suboptimal performance of the furnace in real-time. Operational parameters can be logged throughout the cycle for all cycles for a period of time in order to establish a baseline. This data can then be used to calculate the performance of the process. A regression analysis can be carried out in order to determine which parameters affect different aspects of performance. These relationships can then be used to predict performance during a single cycle in real-time and provide closed or open loop feedback to control furnace operation to result in enhanced performance.
