Determination of volatile matter in samples

Image Number 2 for United States Patent #6074205.

A coal/coke sample is heated under controlled circumstances as a step in determining content of volatile matter. The sample is placed in a crucible having a lid and which is suspended by means of a crucible holder in a heating cavity of a furnace. The invention provides precisely, mechanically guiding the crucible holder and crucible into and out of the cavity to prevent inadvertent touching of the cavity wall by the crucible and thus also to prevent possible dislodging of the lid and spoiling of the sample. The crucible holder is secured to a lid of the furnace, and the furnace lid is guided along upwardly extending guide rods. Lifting and lowering of the lid may be manually. Instead, it may be hydraulically or pneumatically.
