  • Patent number: 9799110
    Abstract: An abnormality detection method of detecting abnormality of a blast furnace from tuyere images shot by cameras installed in vicinities of a plurality of tuyeres of the blast furnace includes: collecting, in a time-series manner, representative brightness vectors defined by representative brightnesses determined based on brightness values of respective pixels for each of the tuyeres image previously shot by the cameras at a same time; extracting a principal component vector by performing principal component analysis on the representative brightness vectors collected in the time-series manner; calculating, as an evaluation value, a length of a normal line drawn in a direction of the principal component vector from the representative brightness vector collected from the tuyere images shot by the cameras at the same time during an operation; and detecting the abnormality of the blast furnace by comparing the evaluation value with a predetermined threshold.

  • Patent number: 4197137
    Abstract: Process and apparatus for calcining finely divided cement raw materials including finely divided combustible materials in a suspension preheater with a calcining furnace. Finely divided calcareous materials are directly charged into the suspension preheater while finely divided argillaceous materials, including combustibles such as oil shale, are charged into a bypass duct for bypassing part of the high temperature gases in the suspension preheater to a calcining zone or calcining furnace. The raw materials charged into the bypass duct are subjected to thermal decomposition, resulting in solids and combustible gases. The combustible gases are separated from the solids and are charged into the calcining zone or calcining furnace while the separated solids are charged into the suspension preheater, mixed with the finely divided calcareous materials, preheated and calcined.
