Abstract
A waste vitrification apparatus () having rotatable mixer impeller () functioning as a shaft electrode () and metallic vessel () functioning as a vessel electrode (). A stream () of waste material and vitrifiable material are mixed and melted in the vessel () for vitrification. The waste vitrification method converts a feed stream () by mixing the feed stream into a glass melt () and melting glass batch of the feed stream () to form a foamy mass. The stream is dispersed by the impeller () to form a foam which is then densified in a settling zone (), recovered through a spout () and solidified in storage containers. Means are provided to adjust the location of the mixing impeller () in the vessel () to change the depth of the settling zone (). The impeller () is mounted on a drive shaft () having a recirculating coolant flow.
