METHOD FOR DETERMINING THE PRESSURE raspiranie COAL OR COAL MIXTURE AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method for determining the bursting pressure of coal or coal mixture by laboratory testing, characterized in that the heating of the sample in the form of coal or coal mixture is carried out in a perforated liner inside the crucible and that between the outer surface of the sleeve and the inner surface of the crucible is granular inert material with granule size exceeding the diameter of the holes in the sleeve; wherein the crucible itself is located in an electric furnace and heated at a rate on the circumference a few degrees per minute from ambient temperature to a final temperature of coal plasticity; the temperature measured by a thermocouple located on the wall of the sleeve and the piston located on the sample above, transmits the pressure force bursting strength measurement sample system and on the basis of this measured force is determined raspiraniya.2 pressure. The method of claim. 1, characterized in that the inert material is coke or anthracite shlak.3. The method of claim. 1, characterized in that the size of the granules of inert material mm.4 1.0-1.5. The method of claim. 1, characterized in that the particle size of the coal / coal mixture in the composition of the sample does not exceed 5 mm.5. The method of claim. 1, characterized in that the heating rate is 3 C / Min.6. The method of claim. 1, characterized in that the temperature measured at the mid-height obraztsa.7. Device for implementing the method determining the pressure distension of coal or coal blend consisting of an electric furnace, and devices for measurement of forces and temperatures and characterized in that the crucible is located inside the electric furnace, the crucible is internally perforated with a sleeve h
