✦ Synopsis
time. The variable force loading enabled the shear rate to be maintained well below the critical one, and thereby to measure the apparent viscosity of coal pellets as Newtonian fluids over 1" temperature range from 600 to 800 K. Upon heating at 10 K min-, the apparent viscosity of Goonyella coal pellet decreased from about 10" Pa s at 640 K down to a minimum of about lo4 Pa s at 755 K, and increased up to lo9 Pa s at 800 K. In a course of heating as above, the viscosity of Blind Canyon coal pellet decreased above 600 K, underwent a minimum of about lo6 Pa s at 715 K, and increased up to 10" Pa s at 770 K. Decreasing the heating rate from 10 to 3 K min-' caused the minimum viscosities of the pellets to increase by l-2 orders of magnitude.
