摘要

PROBLEM TO BE SOLVED: To estimate the distribution of in-furnace gas flow in a furnace gas flowing in the furnace top part, on the basis of the measured values of the gas temperature in the furnace top part, the raw material height in a blast furnace and the total gas flowing amount of the in-furnace gas without directly measuring the flowing amount of the in-furnace gas in the furnace top part.;SOLUTION: An apparatus 34 for estimating the distribution of gas flow estimates the gas distribution of the in-furnace gas flow flowing at the plurality of gas measuring points respectively, on the basis of the measured values of the gas temperatures T_GM measured at the plurality of gas-measuring points in the furnace top part 14, the raw material height R_MN measured at the plurality of height measuring points and the total gas flowing amount G_TL of the in-furnace gas flowing in the furnace top part 14. By this method, the necessity of directly measuring the flowing gas amount or the flowing speed of the in-furnace gas G in the furnace top part 14 with gas flowing sensors, such as flowing amount meter and flowing speed meter having some problems from the view points of maintenance and durability, is eliminated.;COPYRIGHT: (C)2010,JPO&INPIT
