We have developed a new method, Inverse Gas Chromatography (IGC), for evaluating coal fluidity at elevated temperatures. This technique is being used to follow changes in coal structure which affect the coal's fluidity. In IGC, which is used to study polymers, the retention of a probe molecule on the coal surface in a flowing gas system is ...

mesh prepared coal are packed into a retort barrel assembly along with a stirrer. A constant torque is applied to the stirrer and the coal is heated at 3°C/minute. As the coal softens, the stirrer begins to turn. The maximum fluidity value is expressed in dial divisions per minute (DDPM) of the stirrer rotation. • High volatiles: 5,000 to ...

To improve the borehole sealing effect, especially that of coal seam with low permeability and micro fissures, this paper takes the expansion rate of the sealing material as the response value and establishes the quadratic model embracing the expansion rate and various experimental factors by designing orthogonal experiments. The response surface is used to …

The equipment used for this purpose was an IKA A10 grinder with a usable volume chamber of 50 ml previously cooled down with liquid nitrogen. The first step was to cool the plastics by submerging them in liquid nitrogen. After cooling down, the plastics were placed in the grinding chamber and, then, subjected to several grinding cycles.

3.5. Petrographic and Thermogravimetric Analysis. The results obtained from the petrographic analysis giving the maceral composition of the coal samples are shown in Figure 3.Based on the conclusion of [] that a fuel with a higher fuel ratio is more difficult to burn than a fuel with a lower fuel ratio, from Figure 3, the ease of combustion of the coal samples in decreasing order is …

Determining the Fluidity of a Coal (Coal Storage/Coal Preparation) June 10, 1996 To provide a relative measure of the plastic behavior of a coal or coal blend when heated under prescribed conditions. Applies to all incoming coals, new coals and coal blends. Description of Work Activity Much of this work instruction is based on ASTM D 2639.

the fluid continuum in the mixing vessel. The analysis shows that the forces are a result of transient fluid flow asymmetries acting on the mixing impeller. These loads are dynamic and are transmitted from the impeller blades to the mixer shaft and gear reducer. A general result for the form of the fluid force equation can be developed.

The analysis of the changes in the IGP termination temperatures (T e) across the coal charges for the six coals indicated different extents of fissuring in the coke/semi-coke sides. The low fluidity coals (C0 and C1) showed higher T e values at 150 mm, indicating a lower extent of fissuring, in terms of the numbers and proximity to the hotter ...
