Abstract: The invention provides a management system of coal and/or steelmaking dust being managed outdoors. The management system includes an imaging unit, a threshold information acquiring unit, and a determining unit. The imaging unit is configured to perform imaging of heat distribution image information indicating a heat distribution image of a surface layer of a pile of the coal and/or steelmaking dust from a position where imaging of an entire surface layer of the pile can be performed. The threshold information acquiring unit is configured to acquire threshold information indicating a threshold of a temperature of the surface layer of the pile. The determining unit is configured to determine heat generation of the pile based on the heat distribution image information and the threshold information.

Abstract: Provided is an antioxidant capable of coating the surface layer of a coal deposit (coal pile) and further reducing the amount of oxygen permeation into the inside of the deposit. The present invention is an antioxidant for coal, containing an oil-in-water type resin emulsion having an average particle size of emulsion particles of 0.3 μm or more and 1.0 μm or less. The antioxidant preferably further contains a surfactant. The worker sprays the above antioxidant on the coal deposit. This forms a consolidated layer on the surface of the coal deposit that is highly effective in suppressing oxygen permeation. Therefore, the permeation of oxygen in the air atmosphere into the inside of the coal deposit is blocked, thus preventing the oxidation of the coal.

Abstract: The invention provides a management system of a material which is a steelmaking raw material and/or a fuel for power generation and which is managed outdoors. The management system includes an information managing unit, a weather information acquiring unit, and an assessing unit. The information managing unit is configured to manage, for each of piles of the material, powder dust prevention processing information including a presence or absence of existing powder dust prevention processing with respect to the material and a type of the powder dust prevention processing. The weather information acquiring unit is configured to acquire weather information indicating outdoor meteorological phenomena forecasted for the future. The assessing unit is configured to assess an occurrence of powder dust for each of the piles based on the powder dust prevention processing information and the weather information.
