1-2-2 Influences of Residual Carbon and an Inorganic Compound in Coal Ash on Melting Behavior

Abstract

In this study, we investigated the influences of residual carbon and an inorganic compound in coal ash on melting behavior of the coal ash. We prepared the coal ashes with different residual carbon content and with different CaCO₃ amount, and evaluated the melting behavior of the prepared samples based on JIS M 8801. The results indicated that the melting points increased with increasing the carbon content and decreased by CaCO₃ addition.
