ABSTRACT OF THE DISCLOSURE A method of supplying a pulverized fuel mixture to blast furnace tuyeres comprises batch loading the pulverized fuel mixture into a discharging chamber which is under pres-sure, and subsequent continuous distribution thereof from this chamber, and transportation along pipe lines to the blast furnace tuyeres by means of a main gas. According to the invention, after distributing the pulverized fuel mix-ture from the discharging chamber, a supplementary gas is introduced into each pipeline, the total flow rate of said gas exceeding that of the main gas by 3 to 10 times, and the product of the total flow rate of gas within each pipeline by concentration of the fuel mixture therewithin being main-tained equal for all the tuyeres. |
