Rotated truncated pyramids with facet plates widen plasma reaction zones and keep waste from clogging the active destruction area.
Oblong foundry coke from a controlled coal blend improves packing density, lowers latent heat loss, and cuts foundry coke production costs.
Limits inert-rich coal outside the semicoke surface-tension range to maintain coke strength when blending multiple coal brands.
Horizontal-oven coking with coal and recycled breeze produces oblong foundry coke that cuts cost, improves packing density, and reduces cupola smoke.
