摘要： A blast furnace slag level estimation method and blast furnace slag level estimation apparatus can estimate the liquid level of slag to a high degree of accuracy. An operation guidance method, method of producing hot metal, and operation guidance apparatus also provide guidance for the operation of a blast furnace based on a highly accurately estimated liquid level of slag. The blast furnace slag level estimation method includes a step (S2) of calculating a liquid level of melt containing slag for each region in a plurality of regions separated by a low permeability zone, using a physical model that takes at least one of hot metal tapping rate, slag tapping rate, hot metal production rate, and slag production rate as an input and that is based on a mass balance assuming existence of the low permeability zone with poor permeation of slag at a bottom of a furnace.

摘要： To clearly observe the inside of a furnace where an object is heated by a burner. The burner includes: a lens; an imaging device; and a multiple pipe structure including: an inner pipe that surrounds the lens; an outer pipe that surrounds the inner pipe, separated from the inner pipe by a lens coolant passage; a gaseous fuel pipe radially outward of the outer pipe and operable to inject gaseous fuel; a combustion-supporting gas pipe radially outward of the outer pipe and operable to inject combustion-supporting gas; and a cooling pipe outermost in the multiple pipe structure that surrounds the gaseous fuel pipe and the combustion-supporting gas pipe.

摘要： A flame analytics system that may incorporate a burner, one or more sensors at the burner, a historical database connected to the one or more sensors, a model training module connected to the historical database, and a runtime algorithm module connected to the one or more sensors and the model training module. The runtime algorithm may compare realtime data from the one or more sensors and historical data from the model training module in accordance with a machine learning algorithm. The system may further incorporate a fault detection module connected to the runtime algorithm module, a fault diagnostics module connected to the fault detection module, and an enunciator connected to the fault detection module. The one or more sensors may also include having video or acoustic sensitivity of combustion in the burner.

摘要： A viewport for a combustion zone includes an inner casing having a flange extending into the combustion zone. A first layer of ceramic fiber insulation is exterior to the inner casing. A middle casing includes two panes of quartz glass separated by traverse plates. A second layer of ceramic fiber insulation is exterior to the middle casing. An outer casing is positioned to the exterior of the second layer of insulation. The middle casing includes L-shaped ledges having third and fourth layers of ceramic insulation. The panes of glass are each positioned between layers of insulation and the insulation positioned in the L-shaped ledges. The viewport is modular enabling the separation of the first layer of insulation, the middle casing, the second layer of insulation and the outer casing from the combustion zone for maintenance or repair. The viewport minimizes heat migration to the outer casing during use.
