| Abstract: | As the large flow rate and long distance hydrolic transport of ash water mixtures in pipelines is widely applied, the electric power administration put some new demands on the design and operation of hydrotransport system.The hydrotransport characteristics curve of ash water mixtures in pipelines is analysed, and the factor Z is introduced to distinguish flow regions.Therefore a new method is provided for the design of pipelines and the selection of operating velocity. In addition, the reasonable equation for calculating head losses of ash water mixtures in pipelines is given by a comparison between the test results and the calculating results. |
