摘要：

This paper presents an analysis of the ash fusion temperatures (AFTs) for 17 Albanian coals. The contribution of oxides to AFTs is investigated by considering oxides from various perspectives: as discrete species, acids and bases, crystal components, fluxing agents, and cement constituents, and in accordance with the periodic table. Empirical correlations use simple and multiple linear equations and polynomial equations, referring to both weight and molar percentages. The shift from the deformation temperature to the flow temperature is accompanied by a shift of influence from basic oxides to acidic oxides. Many predictive correlative equations are obtained.
