On the optimal distribution of materials in the blast furnace space of the blast furnace
The effect of the uniform distribution of the charge materials in the furnace throat space on various aspects of the blast furnace process is considered. Improved uniformity of distribution can be used as a means of limiting the performance of the furnace in need thereof, for example, due to lack of consumer. Excessively uneven distribution determines the operation of the furnace with a reduced total pressure drop of gas, as an attempt to increase it leads to violations of the vanishing of the charge, including its hanging. According to research the reduction in the total pressure drop of 10 kPa on the blast furnace is accompanied by an increase in specific coke consumption by an average of 8 kg / t of pig iron.
