✦ Synopsis

Coal samples collected from a quenched coal gasifier were characterized for (thermal) heterogeneity by optical reflectance measurements. DRIFT spectroscopy served to estimate the final temperature to which the samples were exposed. Particle size information on the coal samples was superimposed on the results for the thermal history of the char samples collected from the gasifier bed. A good match was found between these different sets of data. The implications for gasifier operation are discussed.
