emissions of methane during coal mining and flaring during oil/gas extraction and refining1. In some cases where countries produce or transport significant quantities of fossil fuels, fugitive emissions can make a much larger contribution to the national total. Combustion and fugitive emissions from production, processing and handling

How to Calculate a Calorific Value | Calorific Value Unit
It is the measurement of the heat value or amount of energy released and is either measured in gcv or ncv. Gross calorific value (GCV) that is Higher Heating Value (HCV) is the amount of heat that complete combustion releases by burning a unit of fuel.
Carbon dioxide emission factor estimation from Indonesian coal
The conversion unit plays an important role in the calculation method. ... The low to medium GCV Indonesian coal samples were estimated as lignite or sub-bituminous one, and high to very high GCV coal samples were categorized as other bituminous. ..., and the average NCV of Indonesian coal samples is 19.8 in MJ/Kg unit or TJ/Gg with a lower ...
Gross Calorific Value
NCV is generally reported on an 'as received' basis. NCV determined by constant volume delivers a slightly higher result than NCV performed under constant pressure. Compared to the GCV (as received), NCV (ar) better represents the practical energy of a coal for a power station, and is a common parameter for thermal coal sale contracts.

GCV vs. NCV
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.
Indonesian Coal
The World Coal Institute gauges that in 2008 Indonesia mined 246 million tons of coal with a little more than 200 millions tons of this traded. 2008 coal sends out involved 173 million tons of steam coal and 30 million tons of coking coal.

Gross Calorific Value vs. Net Calorific Value
Similar to GCV, NCV is typically measured in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (BTU/lb). NCV is particularly useful in applications where the heat generated is not fully utilized, such as in open fires or certain heating systems. By excluding the latent heat of vaporization, NCV provides a more ...
