Abstract
In this laboratory study, gases from mildly heated samples of coal and coal refuse were studied to develop a "signature" for indicating coal sample temperature. Controlled temperature environments were between 100 deg and 250 deg c, and the airflow rates over the sample were between 1 and 2 scf/h. A mixture of air and nitrogen was used at temperatures above 200 deg c to control self-heating of the coal to keep it at the desired temperature. Gas samples were taken periodically and analyzed by gas chromatography.
