    Abstract

    A coal and water fuel was recycled repeatedly through an erosion test loop. The effects of this on the fuel's erosiveness were studied. This was done to determine the feasibility of erosion testing using continuously recycled coal-water fuel. The erosiveness of the coal-water slurry was observed not to be a monotonic function of the number of cycles but was observed to rise to a peak and then decrease. The initial increase in the erosiveness of the slurry was correlated with an increasing liberation of large angular pyrite grains, whereas the subsequent decrease in erosiveness was correlated with the comminution and rounding of the grains of solid matter and with increasing viscosity.
