A METHOD FOR THE DETERMINATION OF THE GAS FLUX DISTRIBUTION IN A BLAST FURNACE

摘要

This invention relates to a method for the determination of the gas flux distribution in the shaft of a blast furnace. The invention is characterized in that: the temperature and optionally also the composition of the gas that has passed through the burden is measured using a probe located above the burden surface, in close vicinity to said surface, at different measurement point (1, 2, 3...) in the cross section of the shaft; and the temperature and composition of the gas mixture are measured at a point (I) located further away from the burden, in which point the gas is completely mixed; and the gas flux distribution is calculated by the use of energy and mass balances for a control volume (V) above the burden surface of the blast furnace, wherein the lower boundary of said volume (V) goes through the measurement points (1, 2, 3...) and the upper boundary of the volume (V) goes through the measurement point (I).
