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 ...

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 ...

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.

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 ...
