GCV is the Gross Calorific Value of the coal. It is denoted as Kcal per example if the GCV of a coal is 4200 Kcal/ means if we are burning 1 kg of coal then the energy liberated is of 4200 Kcal (Kilo Calorie).So for measuring the GCV of the coal, a special equipment is used called Bomb Calorimeter.

Both the petcoke and coal samples were ground, mixed and prepared into standard XRF cups with Etnom® film. For best results, XOS recommends grinding the sample to 325 mesh or finer. Fill the sample cup to at least ¾ full, apply the film, and then tap the samples on their sides, as shown in Figure 1. Tapping the sample helps to compress the ...

The abrasion index (AI) is a measure of the wear caused by the mineral matter in coal. A 2 kg sample of − mm sample is placed in a mill in which four standard metal blades rotate at 1500 r/min for a duration of 12 000 revolutions. The AI is calculated from the loss in mass of the four blades during the test.

This test method pertains to the determination of the gross calorific value of coal and coke by either an isoperibol or adiabatic combustion calorimeter. The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore ...

Determining the Gross Calorific Value in Coal. Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.

Chemical Engineering Journal 354 (2018) 2134 29 juli 2018. DME provides advantages in the valorization of feed streams of low H2/CO ratio, which are formed from feedstocks such as biomass or coal. It is currently accepted that the conversion of oxygenates, such as DME or methanol, to hydrocarbons proceeds via the dualcycle mechanism.
