Abstract

A good knowledge of the rheological behaviour of coal ash deposit at high temperatures and under processing conditions is important for understanding the mechanisms of agglomeration in fluidised-bed combustion and gasification processes of low-rank coals. Rheological characterisation of materials at high temperatures is difficult due to a lack of standard instruments and reliable measurement techniques. We have recently developed a specially designed rheometer that has the capability of measuring the absolute rheological properties of coal ash deposits over a wide range of high temperatures and processing conditions. In this paper, the features of this unique instrument are described and some typical measured rheological properties of coal ashes from different Australian low-rank coals are presented and discussed.
