The coal samples were pulverised to −212 µm size for the spontaneous combustion tests and −250 µm size for both the proximate and ultimate analyses. The proximate analysis for the samples was calculated using the ASTM, with approximately 1 g used to estimate the moisture, ash and volatile matter contents . The fixed carbon is calculated ...

Coal quality analysis. Proximate analyses of the investigated coal samples reveal that the fixed carbon varies from 24.2 to 52.71% (Table 1) and trend shows fixed carbon increases with depth (Fig. 1).Coal maturation has increasing trend with depth, and similar observation was reported elsewhere (Laxminarayana and Crosdale 1999).Volatile matter is in between 32.5 and 48.1%.

All the above mentioned analysis clearly spelt out that the experimental conditions should be 0.2 N KMnO 4 solution with 1 N KOH at 45°C to achieve optimum results for finding out the susceptibility of coal to spontaneous combustion. The results have been validated with Crossing Point Temperature (CPT) data which is widely used in Indian ...
properties of these coal samples were determined by proximate and ultimate analysis. 3.1 Proximate Analysis The moisture(M), Volatile matter(VM) and ash content(A) of coal samples were determined by proximate analysis following the method specified by IS(Indian Standard) 1350, Part - I, and the results are presented in Table 2.
Coal analysis techniques are specific analytical methods designed to measure the particular physical and chemical properties of coals. These methods are used primarily to determine the suitability of coal for coking, power generation or for iron ore smelting in the manufacture of steel .

Hi friends, now we will discuss on the topic coal as a source of energy, as discussed inthe previous module, it is clear to us that coal is mostly used in India for the productionof electricity, around 60% electricity is produced from the coal.Now, you will see why the coal as energy resource, what are the properties and what are the compositionof it, what is the availability and how the coal ...
Ultimate analysis is the elemental composition of coal: C, H, N, and S. This analysis is very important for gasification processes for three reasons: 1. It enables one to determine the amount of oxidant/steam required; 2. The H/C ratio of a coal determines the H 2 /CO ratio in the product gas; and 3. The amount of sulfur in coal must be known ...
