1. Introduction. Consumption of fossil fuels continues to grow, although there are signs that the rate of growth may be slowing [1].Also the abundance and versatility of coals makes a vital role for it in nowadays industrial fields like cement making and conversion to coke for the smelting of iron ore [2], [3].. The calorific value (CV) as an …

Semi Coking Coal : based on (Ash+Moisture) percentage "Useful Heat Value" or "UHV" means the heat value determined on Equilibrated Basis by the following formula: UHV = 8900-138 x [A + M] where UHV = Useful Heat Value in kilo calories per
The aim of the present work is the assessment of properties of 4540 US coal samples from 25 states with reference to the GCV and possible variations with respect …
Occasionally for gas fuels calorific value is quoted on a volumetric basis (Formula F7.2) having units of either kJ/m 3 or kl/scm. The scm (standard cubic meter) is the amount of gas that would occupy 1 m 3 at the ISO pressure and temperature of 101.325 kPa and 288.15 K respectively. Formula F7.3 shows how the number of scm present in a volume of gas …
The calorific value of coal varies considerably depending on the ash, moisture content and the type of coal while calorific value of fuel oils are much more consistent. The typical Gross Calorific Values of some of the commonly used liquid fuels are given below: 1. Fuels and Combustion Bureau of Energy Efficiency 2 Ch-01.qxd 2/23/2005 11:18 AM ...
Gross calorific value (GCV) is an important characteristic of coal and organic shale; the determination of GCV, however, is difficult, time-consuming, and expensive and is also a destructive analysis.
As an indicative standard for coal stored energy, gross calorific value (GCV) has been modeled by many different artificial intelligence "AI" methods such as a feed-forward artificial neural network (FANN), random forest (RF), and support vector regression (SVR) (GCV could be considered for the primary evaluation of coal prices) (Chelgani ...

Coal Specifications. We exclusively trade thermal coal of Indonesian origin and offer three main calorific values – GAR 4200 kcal/kg, NAR 4700 kcal/kg and NAR 5500 kcal/kg. The table below indicates the typical specifications of each category of coal under the American Society for Testing and Materials Standard.
This study is aimed to evaluate the applicability of some existing equations to calculate GCV of Indonesian coal and to develop new equations that more accurate to predict …
The gross calorific value (GCV), also known as the higher heating value (HHV) of coal is the amount of heat emitted upon complete combustion of coal. The GCV of coal is used to estimate various technoeconomic parameters such as boiler efficiency, …
The gross calorific value (GCV) of coal is a key yardstick for many end users pur chasing coal fr om suppliers, as it pr ovides a clear measure of the useful energy content of a coal. ... This GCV prediction formula has been widely applied by some end user industries in India (Dey et al., 2012). In the context of

In this study, relationships among ultimate and proximate analyses of 6339 US coal samples from 26 states with gross calorific value (GCV) have been investigated …
Definition and Calculation. Gross Calorific Value (GCV) and Net Calorific Value (NCV) are both measures of the heating value of a fuel. GCV represents the total amount of heat released when a fuel is burned completely, while NCV takes into account the heat lost in the process of combustion. GCV is calculated by measuring the heat produced when ...
In this study, the gross calorific value (GCV) of coal has been estimated using two types of coal analysis data. These are proximate data and spectral reflectance data in visible to near infrared ...
Numerous empirical equations have been published to correlate the gross calorific value (GCV) of coals with the result of proximate or ultimate analysis, however, many researchers continue to propose new equations. One of the reasons is that many existing equations are likely fitted to coal of one region only. This study is aimed to evaluate the applicability of …
