Inasmuch as some of the ash analyses were made on prepared coals, some information is presented on the effects of prep- aration (sizing and washing) on ash composition. The rela- tion of ash composition to ash softening temperatures has been indicated inthree Composition of the ash of Illinois coals.

File name: Why is coal composition and quality important to gas analysis. To begin with, the chemical composition of coal is analyzed by proximate and ultimate analyses (ASTM, ).Proximate analysis determines by using set procedures regarding moisture, volatile matter, fixed carbon, and ash content (Figure ).Proximate analysis is reported by percent on as-received, moisture   assessed and nonassessed coals in the Illinois Basin.

E27 2. Summary descriptive statistics of proximate and ultimate analyses, calorific values, forms-of-sulfur analyses, and ash-fusion temperatures for all assessed and nonassessed coals in the Illinois Basin as analyzed by the Illinois State The optimum ash content is mostly an economical decision.

The increase in hot metal cost should be balanced against the gains from using high-ash coals. There is increasing attention on the ash composition of coal, particularly with respect to Al 2 O 3, SiO 2 and alkalis. Alumina affects the slag fluidity, while silica in the ash has a strong   The average ash content of Illinois coals is about midway between these two extremes, or about 10%, with local variations commonly in the order of 2 to 3%.

Ash must not be confused with mineral matter which is the form in which most in-combustible components occur in coal. The composition of mineral matter in Illinois coals   ASH YIELD (Weight %, dry) OF THE INDIANA SPRINGFIELD COAL Source: M. Mastalerz, A.
