Abstract

PURPOSE: To accurately measure the tackiness of sample coal by placing the sample coal in a retort to heat the same, and inserting a needle pin into the coal to measure the resistance received thereby.
CONSTITUTION: Sample coal is placed in a retort 26 to be heated, and a needle pin 34 is vertically moved to be inserted into the sample. A resistance received by the needle pin 34 when it is inserted into the sample coal is converted into a mechanical amount by bellows. The displacement of the bellows is converted into an electrical amount by a sensor 24. An amount of insertion of the needle pin 34 is detected by a sensor 36. On the basis of outputs from these sensors 24, 36, a plastic layer and a coke layer as well as the heights of these layers are determined.
