Features 01
Expected Problems
?Isn't it hard work to control the reaction in the blast furnace due to inadequate estimation of the coke particle size distribution?
?Can the effect of the small diameter coke (coke fines) ratio (fine ratio) be estimated with good accuracy?
?When the fine ratio is larger than expected, doesn't it lead to poor furnace gas permeability and deterioration of the furnace condition?
?Are you having problems measuring the particle size distribution (including fines) of other materials, not limited to coke?
Features 02
Technology highlight
?Hybrid method combining measurement of coarse particles (>5mm) and fines (≤5mm).
?Coarse particles are measured with a laser distance meter, and a camera is used for fine particles.
?The fine ratio is measured as the moisture content and converted to the fine ratio.
?Measures to suppress adhering dust to the sensor window are implemented, enabling stable measurement.
Features 03
Proposed Solutions (Examples)
?Measurement of coke particle size distribution as blast furnace operation support data.
?Particle size distribution, including fine ratio information, for the necessary lines (premised on the fact that the amount of adhering particles has a correlation with the moisture content).
