·5800 6000 GAR Product Specification SAFFRON Group has wide range of Indonesian Thermal Coal like 3200 3400 3800 4200 4500 5000 5500 5800 & 6500 GAR Coking Coal is also available COAL PARAMETER TYPICAL REJECT Total Moisture ar 10 66% Gross Calorific Value ARB 6069 Kcal/Kg Above 5800 Kcal/Kg
·"Explore the comprehensive guide to coal grades covering G1 to G17 classifications Understand the nuances of coking and non coking coal ash content moisture levels and calorific values GCV whereas the grading of coking coal is based on ash content For semi coking or weakly coking coal the classification considers both ash and
·Coal Platts coal pricing methodologies 2 1 Platts coal publications assess prices in the Following formats 2 2 All Platts coal assessments share the following Steam coal is quoted on a GAR Gross As Received basis except for Europe/ARA Richards Bay 6 000 kcal/kg and Japan and Korea West CIF which are quoted on a NAR Net As
SGS calculates calorific values total hydrogen and CSR/CRI values with coal analytical calculations Rely on SGS the coal and coke leader for accurate and precise calculations % and GCV db 300J/g converted to as received basis are used in the calculation of Uncertainty Fuel Ratio = Fixed Carbon / Volatile Matter Ballast
Volatile matter Volatile matter is the material that is driven off when coal is heated to 950 °C in the absence of air under specified conditions It consists of a mixture of gases low boiling point organic compounds that condense into oils upon cooling and tars In general coals with high volatile matter content ignite easily and are highly reactive in combustion applications
·The GCV or higher heating value HHV is an indicator of chemically stored energy content of a coal [7 8] It is usually a decisive parameter in the assessment of the value of the coal and thereby provides a basis for its purchase agreement [9 10] GCV is the amount of energy released during the combustion of a coal
Coal analysis gcv adb basis formula Reckoner for all Coal Conversions The difference between net and gross as received NAR vs GAR specific energy values is the latent heat of the water vapour which lowers the effective calorific value in the boiler To convert from GAR to NAR for bituminous coals subtract approximately 109 mjkg 260 kcalkg 470 btulb
·Since GCV was one of the key factors used for energy billing Audit compared the GCV as billed by coal companies for coal loaded on to wagons GCV of coal as received at the unloading point of the power station and GCV of coal as fired in the boilers for a year from October/November 2012 to September 2013 26 in the stations
