The defluidization behaviour of ash derived from Indian coal by combustion in a fluidized bed has been studied. Sintering temperatures for ash in several ranges of particle size were measured with a dilatometer. In agreement with the earlier work on other coals it was found that above the sintering

Australian bituminous coal (Hoskisson) was gasified with oxygen and steam in a 0.4m diameter spouted bed reactor at atmospheric pressure and temperatures of 1050-I 170Β°C to produce medium calorific valuegas. High-ash agglomerates fell through the throat of the spouted bed under restricted gasificati

Burnout times of high-ash coals in a fluidized bed were determined for coal panicle sizes ranging from 0.125 to 4 ram, over a temperature range of 973-1173 K and fluidization velocities varying from 3.7Umf to 6.2U,,f. The results show that the mode with which anthracite particles burn resembles that
