Equipment for measuring the reactivity of chars from highly reactive coals, based on recent Norwegian developments, has been assembled. Measuring techniques are described, and the results of measurement with a range of New Zealand coals are presented. The measured reactivities are compared with resu

The ash fusion temperatures of 20 analysed samples of pulverized fuel ash obtained from the Meremere coal-burning power station have been determined. It is shown that the fusion temperatures can be related to the acid-soluble calcium and iron oxide contents, and that it is possible to predict the so
