The proximate analysis of coal separates the products into four groups: (1) moisture, (2) volatile matter, consisting of gases and vapors driven off during pyrolysis, (3) fixed carbon, the nonvolatile fraction of coal, and (4) ash, the inorganic residue remaining after combustion. The proximate analysis of coal is presented as a group of test ...
coal. For the analysis of volatile matter in coal, each sample of 1 gram of air-dried coal (ground to pass through a -212 microns IS sieve) was taken into a crucible with a lid and placed in the muffle furnace, which was already at a temperature of 9000c for a period of 7 minutes. Then the differences in the weight loss were calculated before ...
Analysis of Coal The quality of coal can be analyzed by two analysis; proximate and ultimate analysis. Proximate analysis: In this analysis moisture, volatile matter, ash and fixed carbon can be determined. Moisture: A known amount of finely powdered air-dried coal sample is taken in crucible.
Geologists also classify coal types according to the organic debris, called macerals, from which the coal is formed. Macerals (microscopic organic constituents found in coal) are identified (microscopically) by reflected light - the reflective or translucent properties of the coal indicating the individual component macerals

Analysis of coal To assess the quality of coal, two types of analysis are made. 1. Proximate analysis 2. Ultimate analysis Proximate analysis It involves the determination of percentage of moisture content, volatile matter, ash content and fixed carbon in coal. i) Moisture content
Ovbiowun coals have 65 HGI and Oloku coal is 87 HGI due to higher moisture content. The moisture content of Oloku coal (15.0) is higher than Ovbiowun (10.8) while the volatile matter (as received) for Oloku (40.7) is lower than Ovbiowun (41.7). From the > 10% moisture and ash content, coal in both study area is unsuitable for coke production.
Coal combustion, boiler heat transfer, ash formation, ash particle aerodynamic, and ash particle sticking models are all essential steps in this process. The model described herein addresses the prediction of ash particle size and composition distributions based upon combustion conditions and coal parameters.
COAL PETROLOGY: Coal type is related to the type of plant material in the peat and the extent of its biochemical and chemical alteration. Type can be assessed in terms of variety of petrographic analysis. Coal petrology is concerned with the origin, composition and properties of the distinct organic and inorganic components of different coals.

FIGURE 7-3. Variation of selected coal properties with coal rank. The chemical approach to characterizing coals is to determine the amounts of the principal chemical elements in them. In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal.
