The concept of a yield value is important to many areas of slurry coal water fuel transport such as in predicting its stability or estimating the pressure requirements for pipe-line start-up and turbulent flow. This paper describes techniques to accurately measure coal water fuel yield point. In order to display a wide variation in coal water fuel properties, slurries made from two Western Canadian coals were made available to CRL for yield point study. The proprietory Salzgiter Industrial AG technology (DENSECOAL) was used for a low volatile or bituminous coal (A) and the CARBOGEL process for a medium volatile bituminous (B).
