The replacement of conventional metallurgical coke in cupolas with anthracite fines formed into bricks with hydrolyzed collagen, lignin and other additives burn as fast as coke while producing 35-40% more energy per volume.
Emission Check: Replacing Coke With Anthracite Fines
The first of these options is to use waste anthracite fines formed into bricks to partially replace coke and ferrosilicon (see Figure 2).
The facility briefly served as an export terminal for anthracite fines
to Korea until the mid-1980s.
