STAMP CHARGING –

higher density, optimized coke quality

During the stamp charging process the coal is compacted outside the coke oven, into a single „briquette“ (coal cake), having almost the same dimensions as the oven chamber.

This coal cake reaches a density of more than 1.1 t/m³ (on wet coal basis with 10% water) – about 30% more than with the loose coal-charge during conventional top charging systems.
