The furnace is used for the determination of volatile matter in coal and coke by ASTM methods.  The furnace is equipped with a chromel wire basket which supports a crucible containing the coal sample in the furnace and which is always positioned at the same depth in the furnace to duplicate the conditions of volatilization.

The heating chamber is 1-1/2" in diameter and 6" deep and consistes of  a refractory cylinder on which the heating element wire is cemented.  A thermocouple may be inserted through a hole in the bottom of the furnace so that it touches the bottom of the crucible, permitting accurate temperature measurement during the test.

Overall dimensions are 5-5/8" in diameter and 12-5/8" in height.  Power consumption at full load is approximately 360 watts.  A furnace controller is required for proper control of operating temperatures.
