ABSTRACT:
A method for disposal of sodium containing waste material comprising combustion sodium containing waste material and a silica bearing material in an incinerator having interior walls lined with a refractory material which tends to react with metallic sodium and deteriorate. The sodium containing waste material comprises sodium salt and/or bases and by providing reaction conditions whereby the metallic sodium tends to react with silica to provide a combustion product including a sodium silicate compound, the combustion is carried out in manner to reduce deterioration of refractory materials by reaction with metallic sodium. Also disclosed is a method for the simultaneous disposal of sodium containing waste material and rice hulls which contain silica and provide a portion of the combustion energy.
