Abstract

The raw Tarmi coal having ash content of 33.1 % was de-shelled to produce pre-clean of 23.2 % db ash content and then further beneficiated to produce clean coal samples of ash contents of about 13, 16 and 19 % respectively. These concentrates contained inertinites more than 70 %. Pilot oven carbonization tests were carried out by replacement of 10 % indigenous MCC and 13 % indigenous PCC under top charging conditions for clean coal samples of all three ash levels. One blend at 20 % usage level of clean Tarmi coal of 13 % ash level was carbonized under stamp charging conditions. It was observed that Tarmi coal is usable in BF coke making and it can be used gainfully under stamp charging conditions.
