AIST - 2018 AISTech Conference Proceedings

The coal mass (having moisture content of 10-11%) is stamped to achieve bulk density of more than 1 ton/m3 before charging. This stamped coal mass, called coal cake, is then charged into the ovens where average carbonization time of 64-65 hours is maintained. The coke produced is quenched with the help of water before dispatch.
