Data from 23 low-rank coal slag viscosity determinations have been employed in attempts to correlate the linear portion of the log viscosity vs. temperature curve with five published empirical correlations for silicate slags. Of these five correlations, one developed by Urbain for metallurgical slags appeared to give a reasonable fit to the experimental data for nearly two-thirds of the viscosity tests. When the slags were subdivided into three groups, based on a parameter of the Urbain equation that is roughly proportional to silica content, it was possible to derive modified forms of the Urbain equation that gave acceptable correlations (within 30 percent) for 11 of the viscosity tests. Of the remaining 12 tests, the modified correlations were marginally acceptable (within 60 percent) in five cases. (JMT)
