Abstract

PURPOSE: To supply the cold air in blast pipe to the hot stove and lower the temperature of the exhaust gas in the next process by providing a heat exchanger in the blast pipe of the hot stove and operating the same at the final blast period of the hot stove.
CONSTITUTION: The air of the piping line 9 of the blower for blast furnace is heat- absorbed to become cold wind by the heat exchanger 3 installed to the main blast pipe 2 at the final blast period of a hot stove 1 and this cold air is sent into a regenerating chamber 5. The temperature in the lower part of the regenerating chamber 5 is lowered by this cold wind effect. When the compressed air for combustion of the hot stove 1 is supplied from the piping line 6 from the pressure exhaust process and combustion process of the next step, the exhaust gas having been cooled is released to the outside through a flue 10. By releasing the exhaust gas at a minimum heat quantity in this way, the heat quantity in the regenerating chamber 5 is utilized to the maximum possible extent and the heat efficiency of the hot stove 1 itself is improved.
