CCTR Indiana Center for Coal Technology Research 6 COAL RANK Anthracite coal is a dense, hard rock with a jet- black color & metallic luster. It contains between 86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke
SGS global teams of chemists and experts use a range of coal analytical calculations and indexes to arrive at the calorific values, total hydrogen, Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) of your coal sample. CCTR Indiana Center for Coal Technology Research 6 COAL RANK Anthracite coal is a dense, hard rock with a jet- black color & metallic luster. It contains between 86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers. Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite. Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. From 01.01.1985, coal was graded as A to G (Seven grades) basing on the Useful Heat Value. As per GoI Notification, from 01.01.2012 onwards coal is being graded on Gross Calorific Value (GCV). There are 17 GCV grades starting from 2201K.Cal/Kg (G17) to above 7000K.Cal/Kg (G1). GCV bandwidth between two successive grades is 300 K.Cal/Kg.

Anthracite Coal is very shiny, hard black coal, high carbon content and energy density, repels moisture, for domestic industrial uses, including smokeless fuel; Bituminous Coal is softer and shiny, moisture content is 8 -20%, possible for coking coals, volatile matter from 16% - 40%, can be used for thermal or metallurgical applications; Sub-bituminous Coal is soft and black with energy The Grade/GCV range will come into effect on & from 01.04.2015.
