Bibliography: leaves 322-335. / xxxvii, 343 leaves : ill. ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Highlights the need for extensive testing of large particle coal devolatilization models with both volatile matter evolution and particle temperature data in order to ensure that the predictions generated by the model can be thoroughly trusted. By undertaking an in-depth investigation into the particle temperature measurements and associated model predictions, shows that accurate model predictions can be obtained for the evolution of volatile matter, and of individual volatile species. The model is also capable of predicting the behaviour of wet coal particles by assuming that drying is heat transfer controlled and that the enthalpy of drying observed by Chen is applicable. Ultimately, this model forms a sound basis for the on-going development of a model encompassing all of the reactions required to model the behaviour of a typical coal particle in a fluidished bed combustor or gasifier. / Thesis (Ph.D.)--University of Adelaide, Dept. of Chemical Engineering, 1999

Due to many unexpected difficulties which developed as the method was being worked out, all of the desired information on these coals was not obtained. Therefore, most of the allotted time has to be devoted to the standardizing of the apparatus. Many of the small but important points of technique, which gave trouble, have been overcome. / M.S.
