Ash transport in galvanised steel pipes. May 1969.

Abstract

Results of an experimental program to evaluate the head losses of ash slurry flow (Vales Point and Wangi) in one inch and two inch galvanised steel pipes carrying ash concentrations form 10 to 60 percent by weight. Results compared with theoretical results as predicted by by the effective viscosity method. Further tests should be effected to evaluate the effect of pipe roughness, with steel, cast iron or plastic pipes. Head loss is not sensitive to ash particle specific gravity or viscosity variations. A small amount of detergent in the slurry diminished head loss.
