Abstract

PURPOSE: To economize fuel such as heavy oil by effectively utilizing waste combustion exhaust gas due to the air-heating furnace of a blast furnace as a portion of heat source, when iron-ore is charged into a drying-classifying machine, and the ore is supplied to the next process such as pulverization, after drying and classification.
CONSTITUTION: As to the air-heating furnace 3 of a blast furnace 1, lining material is stretched on the inner surface 19 of a combustion chamber 18, and a burner 20 blows-Out flame in the direction of tangent to the chamber 18 in cyclindrical form, and combustion air and fuel are sufficiently mixed, and perfect combustion is achieved. The combustion air which flows-in through a combustion air inlet 21 generates combustion gas at 1000W1200°C in the chamber 18, and the combustion exhaust gas supplied to an exhaust gas inlet 17 from the furnace 1 through an exhaust gas pipe 14 is mixed with said combustion gas in a mixing chamber 22 so that the temperature is decreased to an arbitrary value, and the mixed gas is charged into the drying-classifying machine 2. The iron ore 4 charged in a hopper 32 is dried and classified by a motor 33
