When the excess steam produced during the pyrolysis process is sold back to the host mill, it reduces the demand that the mill has for coal for its existing steam generation. The equivalent amount of coal that is replaced is calculated using a steam-to-coal correlation previously developed by Petersen et al. [ 39 ].
