Results are given for a run in which approximately 10 tonnes of Loy Yang (Victoria, Australia) coal were dried in a continuous run* Interesting features are commented on* Among matters important for design is the effect of the heat-transfer surface. The paper reports findings of studies in measuring local pressure-gradients and pressure fluctuations and comments on the significance for design. Some calculations are also presented in regard to a multiple-effect dryer system with one dryer at elevated pressure, one at atmospheric pressure and one at atmospheric pressure but with the operating temperature at, say 76°C.
