EXPERIMENTAL STUDIES ON THE HYDRAULIC TRANSPORT OF COAL

The results of an experimental programme on the hydraulic transport of coal are summarized. The behavior of coal-water mixtures was investigated in 50, 100, 150, 200, 250 and 300 mm diameter pipelines. Solids concentrations were varied from 20 to 50% by volume. Pressure drops and deposit velocities were recorded. The importance of accounting for surface phenomena is discussed. This paper summarizes the experimental results of the work with coals and has two objectives: to present accurate data for metallurgical coals, and to present some of the difficulties in obtaining accurate data for various coals and hence to advise caution in interpretation of data in the literature.
