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 ...

Coal Centre Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal
The gradation of noncoking coal is based on Gross Calorific Value (GCV), the gradation of coking coal is based on ash content and for semi coking /weakly coking coal it is based on ash plus moisture content, as in vogue as per notification. Grades of Coking Coal. Grade. Ash Content. Steel Grade I. Not exceeding 15%.
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 ...
This document specifies a method for the determination of the gross calorific value of a solid mineral fuel at constant volume and at the reference temperature of 25 °C in a combustion vessel calorimeter calibrated by combustion of certified benzoic acid. The result obtained is the gross calorific value of the analysis sample at constant ...
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 ...
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.
determination coal GCV, many scholars have been carried out to investigate the relationship between GCV and proximate analysis (, FC, A, VM, and M) as well as coal properties [ 26
Gross calorific value (GCV) is one the most important coal combustion parameters for power plants. Modeling of GCV based on coal properties could be a key for estimating the amount of coal consumption in the combustion system of various plants. In this study, support vector regression (SVR) as a powerful prediction method has been used to investigate relationships among coal sample properties ...

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.
