Ash Evaluation of Indonesian Coal Blending for Pulverized ...

Coal calorific value is one of the main considerations for using coal as a power plant fuel. In addition, the requirements for indications of slagging and fouling are also important to maintain combustion efficiency. However, coal power plants often experience problems in boiler operations due to the use of certain types of coal, even though they have a relatively high calorific value.

Coal analysis - Wikipedia

Coal with less than 69% fixed carbon is classified by its heating value. Volatiles and carbon are on a dry mineral free base; heating value is based on the moisture content as mined, but without any free water. The ISO also has a coal ranking system, though its subdivisions do not align with the ASTM standard.

A disc of coal was solvent-extracted and dried using the same procedure as used for the crushed coal to investigate the effects of solvent swelling and changes to the coal ultrastructure. The coal showed obvious cracking along bedding lines after solvent extraction and drying when observed by eye ( Supplementary material 3 ).

Fuel and Energy Conversion and Equivalence Chart

To use the formula below, remember to use a decimal for the appliance heating efficiency you are assuming (see Table 2). You must first convert the Btu content of the fuel per unit to millions of Btu by dividing the fuel's Btu content per unit by 1,000,000. For example: 3,413 Btu/kWh (electricity) divided by 1,000,000 = 0.003413.

Dry, mineral matter-free basis: Data or results are calculated to a theoretical base as if there were no moisture or mineral matter in the coal sample (ASTM method D388-12; American Society for Testing and Materials, 2013, p. 390–396). For this basis, a calculation is needed to determine mineral-matter content rather than ash yield.
