No.1-24 Influences of Residual Carbon and an Ash Composition in Coal Ash on Melting Behavior

Abstract

In this suduy, we investigated the influences of residucal carbon and ash composition in coal ash on the melting behavior by measuring the melting temperatures of the ash and char with diffrent residual carbon and CaCO₃ contents. The melting temperatures evaluated by JIS M 8801 increased wih increasing the residual carbon content, while the temperatures decreased with the addtion of CaCO₃. The decrease of the temperatures of CaCO₃-added ash and char depended on their residucal carbon content.
