In stamp charged coke making, the stamped coal charge expands first as one body and later shrinks-the width of the final coke mass is generally more than the initial width of the coal cake The major factors responsible for the dilation behaviour of any coal charge during carbonization are: a) rank of the coal charge; b) the bulk
