The essence of GCV is a concentrated expression of moisture, volatile matter, ash, fixed carbon and other elements. The moisture evaporates in coal combustion, which consumes calories. The ash can affect GCV, which reduces the proportion of combustible portion. There are nonlinear relationship between GCV and mineral composition of coal [35 ...

Ash and total moisture ranked as second and third importance variables (respectively) that negatively correlated with GCV. Increasing ash resulted in a lower coal organic content (lower carbon percentage) which reduces the heating value, and growing the moisture content weakens the coal structure and decreases the GCV of samples (negative ...

Gross calorific value (GCV) is one of the essential parameters for evaluating coal quality. Therefore, accurate GCV prediction is one of the primary ways to improve heating value as well as coal production. A novel evolutionarybased predictive system was proposed in this study for predicting GCV with high accuracy, namely the particle swarm optimization (PSO)support vector regression (SVR ...

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.
