Abstract

The flow characteristics of slags formed by burning of western Canadian coals were characterized by means of high-temperature viscosity measurements. The results show that there is a general linear relationship between viscosities and SiO2 /Al2 O3 , SiO2 /(Al2 O3 + Fe2 O3 ) mass ratios and base/acid ratio of the slags. It can be concluded that the viscosities of the slags are sensitive to compositional variation. Attempts were made to correlate the viscosities calculated by Watt and Fereday and Bomkamp’s modified methods with the measured viscosities. The correlation is unsatisfactory. The computed viscosities are higher than the measured values.
