Abstract

In the course of this project a method was developed for measuring radial gas distribution at the blast furnace top. The measuring instruments currently installed at the furnace top do not really give an accurate picture of radial gas distribution, whereas the new method opens up new possibilities for optimising the flow of gas in the blast furnace and the corresponding rate of fuel assumption. First, a co-ordination system was established for the three techniques (layer thickness measurement, thermoprofilometer/central probe and spirotherm). Material characteristics were then computed and models developed for computing radial gas distribution, based on co-ordination system data. Finally blast furnace tests were carried out and the performance of the system evaluated. By combining the coke and burden layer thickness data measured at the furnace wall, the gas and burden profiles measured across the radius, and the material temperature distribution, it was possible to determine the isochronous radial gas distribution.
