入炉煤水分对炼焦过程及焦炭质量的影响

Influence of coal charge moisture on coke-making process and coke quality

通过测定入炉煤水分分别为1%、6%和12%时煤料堆密度、升温速度及坩埚焦性质,得出入炉煤水分对其性质的影响。降低入炉煤水分虽然对煤料本身性质影响不大,但是其在炭化室内结焦过程的动态发生了显著变化,可显著提高焦炉生产能力及改善焦炭质量。入炉煤水分为1%时,煤料堆密度、升温速度及坩埚焦的性质都大大好于入炉煤水分为6%和12%这两种情况。

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%.
