Title:
複合アーク溶解炉排ガスの改質方法および複合アーク溶解炉
Document Type and Number:
Japanese Patent JP5617667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for reforming exhaust gas of a combined arc melting furnace and a combined arc melting furnace which can reform the exhaust gas generated when melting a cold iron source using the combined arc melting furnace without causing the deposition of carbon, dust or the like and can increase of the latent heat of the exhaust gas.SOLUTION: In the method for reforming the exhaust gas generated from the combined arc melting furnace comprising a melting chamber and a shaft-type pre-heating chamber which is vertically provided on the upper part thereof and communicates to the melting chamber, the cold iron source successively lowers inside of a pre-heating chamber, is pre-heated by using a high temperature exhaust gas generated in a melting chamber, and is continuously introduced into the melting chamber to arc melt, an ammonia gas is blown into the pre-heating chamber while blowing a carbonaceous material to be an auxiliary heat source in the melting chamber under conditions wherein the cold iron source is present striding over the pre-heating chamber and the upper part in the melting chamber.
