Abstract
An analyzer is provided for use in determining the volatile matter content of coal and coke. The analyzer automatically adjusts a position of a crucible containing a coal or coke sample relative to a furnace depending upon the temperature of the crucible. The crucible is supported and the temperature of the crucible and sample is sensed by means of a thermocouple arranged as a sling for contacting the crucible. The sensed temperature is compared with a predetermined and desired temperature. A comparison difference triggers a vertical movement of the crucible and sample, within the temperature profile of the furnace, using a servomotor until the crucible is positioned such that the sensed temperature and desired temperature correspond.
