The Sintering Characteristics of Industrial Solid Waste Incinerator

Abstract:

Burning the industrial solid waste can form low melting point alkali salts to cause heavy sinters in the incinerator. The utilization of additives is proved to be effective to reduce the sintering in this work. Three additives (lime, kaolin and coal ash of an electric power plant) were mixed in different proportions with the industrial solid waste, and then an ash fusibility test was performed on the solid waste and the mixtures. The results show that, the solid waste exhibits a low melting point and the chemical additives can increase it efficiently. Furthermore, the anti-sintering mechanisms may conclude that the additives react with the alkali salts in the solid waste to form the high melting point materials.
