“…The blast furnace charging simulation provides data, which are otherwise obtainable in very complicated and costly ways. The computational core of the simulation can utilize analytical calculation methods or other advanced finite element methods [18]. The main advantage of analytical methods is the significantly lower processing power requirement and thus the speed of the performed simulation.…”

This article describes the simulation method for layering the components of the charge in the blast furnace, including the particle size distribution and gas flow distribution of bell-less top charging systems in blast furnaces. The Burden Distribution application, which simulates the charge in blast furnaces operated by the company Třinecké železárny (ironworks) to optimize the production of pig iron, applied this simulation method. Based on the parabolic trajectory of the material falling from the tilting chute of the bell-less top charging system, the method is calculating the profile of individual charge layers. The material forms after impact according to known angles of repose, segregating into individual granulometric size fractions. The data incorporated into the simulation enables the estimation of charge and gas flow distribution along the radius of the blast furnace shaft. The article presents the used mathematical models and equations, including algorithms of the simulation.

“…It can be seen that the mentioned models [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ] differ from each other not only in the method used but mostly in the type and place of input data collection. The less intrusive the measure, the more sophisticated the modeling methods used.…”

Coke is the only batch component that does not soften in blast furnace thermal conditions. It is especially important at the temperatures of the cohesive zone forming because coke layers are the only gas-permeable charge. The aim of the work described in this article is the identification of individual coke layers situation in the cohesive zone. Numerical calculations of the cohesive zone situation are based on the horizontal below burden probe measures, however, coke layers are calculated using analytical geometry. The results can be presented as a bitmap; the individual and total area of the coke layers passing gases through the cohesive zone is also calculated. This form of results allows for subjective but quick assessment of the blast furnace operation by its crew.
