Abstract
PURPOSE:To stabilize the temperature of the preheated air always at a constant temperature, by detecting the temperature of the preheated air entering into the hot stove for blast furnace and actuating the supplementary preheater when the above temperature is low. CONSTITUTION:The waste gas 5 of high temperature from the hot stove 1 gets away to the stack 8 through the intercepting valve 4, but on the other hand, a part of the above gas is released to the stack 8 passing through the air preheater 9 though the ducts 6 and 7. The air 11 for combustion in the hot stove is heated at the air preheater 9 and enters into the hot stove 1 passing through the main pipe 19 for the air for combustion. At this time, the timeperature of the preheated air 13 is measured with the temperature detector 18 and is compared with the temperature of the temperature setter 16 with the controller 17 for combustion. At the case where the temperature of the preheated air 13 is lower than the above set temperature, by controlling the operation of the supplementary preheater 14 with the controller 15 for combustion on the basis of that signal, the timperature of the preheated air 19 is maintained always at a definite set temperature. As the result, the amount of coke oven gas for combustion is saved and the state of operation of the furnace is stabilized.
