焦化产业作为高能耗、高污染产业,具有巨大的节能减排潜力。以焦炉物料平衡和热平衡计算为基础,计算焦炉的热效率,对焦炉的能耗进行分析。采用回收焦炭显热的干熄焦技术、荒煤气余热利用技术和以焦炉废气余热为热源的煤调湿技术,以充分利用焦炉支出热,达到节约能源、改善环境、提高经济效益、降低炼焦耗热量和提高焦炉生产能力的目的。
Though coking industry is highly energy-consuming and heavily air-pollutant,it has tremendous potential of energy saving and emission reduction.Based on the material balance and heat balance calculation,thermal efficiency of coke oven was calculated and energy consumption of coke oven was analyzed.To make full use of waste heat of coke ovens,such technologies as coke dry quenching（CDQ）,waste heat recovery of raw gas and coal moisture controlling（CMC） via recovered heat of flue gas should be adopted.It is expected to save energy,improve environment,enhance economic returns,and improve the coke oven production.
