Abstract

PURPOSE:To recover a Co-contg. exhaust gas as an effective gas and make effective use of said gas without releasing the same to the outside and without exploding CO gas by contaning an oxygen top blowing converter and an exhaust gas capturing skirt in a hermetic chamber and communicating the same with a forced-draft fan. CONSTITUTION:A converter 1 and a skirt 9 are contained in a hermetically closed chamber 10 and a forced-draft fan 11 is connected to the hermetic chamber 10. Raw materials such as molten iron and scraps ar charged into the converter and oxygen blowing is started through a lance 8. The exhaust gas of less CO contents in the early and end periods of the blowing is burned by the air admitted by the forced- draft fan 11 to an inert gas which is then passed through a cooling tower 2 and a dust collector 3 and is released from a releasing tower 7. The gas of a high CO content in the oxygen blowing peak period is passed through the cooler 2 and the dust collector 3 and is stored as a valueable gas having been cooled and removed of dusts in a gas holder 6. The gas of a high CO density may be safely recovered without sucking air from the furnace port.
