Abstract
Plasma type ash melting is increasing attention as the method of volume reduction, detoxification and recycling of incineration ash from municipal refuse. This paper describes operation results of plasma type ash melting furnace in Koyamagawa Clean Center that was completed in March 2000. The operation results have clarified (1) the material balance and element balance on ash only melting, (2) the heat balance and the relationship between ash feeding rate and plasma power consumption rate on ash only and fly ash mixed melting, (3) the plasma torch electrode lifetime and wear speed.
