Abstract:

By measuring coal bulk density, temperature rise rate and crucible coke nature when coal charge moisture were respectively 1%, 6% and 12%, the influence of coal charge moisture on their nature was obtained. Although there was no big influence on coal charge nature lower coal charge moisture by lowering coal charge moisture, the dynamic state of coal charge in the coking process in oven chamber has changed substantially, which can greatly increase coke oven productivity and improve coke quality. When coal charge moisture was 1%, coal charge bulk density, temperature rise rate and nature of crucible coke were much better than that of coal charge moisture of 6% and 12%.
