Aug 17, 2015· FROM GAR TO NAR The difference between net and gross as received (NAR v/s GAR) specific energy values is the latent heat of the water vapor which lowers the effective calorific value in the boiler To convert from GAR to NAR for bituminous coals subtract approximately: 109 mj/kg 260 kcal/kg 470 btu/lb Applicable for bituminous coal
Higher and lower calorific values (=heating values) for some common fuels - coke, oil, wood, hydrogen and others Sponsored Links Energy content or calorific value is the same as the heat of combustion , and can be calculated from thermodynamical values , or measured in a suitable apparatus:
In August, the daily Platts FOB Kalimantan 5,900 kcal/kg GAR coal assessment averaged $7768/mt, down from $8296/mt in July, while the daily 7-45 day Platts Newcastle FOB price for coal with a calorific value of 6,300 kcal/kg GAR averaged $11829/mt, compared with $12074/mt in the previous month
(ii) Calorific value harmonization across indices and normalization: Indonesian coal calorific values given in the Platts index are on gross as received (GAR) basis, and that of API-4, Coalfax and Globalcoal are on gross air dried (GAD) basis To maintain consistency, Indonesian coal calorific value was also converted to GAD basis
GAR is ((100-total moisture)/ (100-inherent moisture)) x Calorific Value in ADB So all depends on the moisture If we assumed total moist 25% and inherent 5% so the calorific value in ADB is (95% .
