一种无烟煤型焦洁净生产技术

介绍一种符合国家可持续发展战略的洁净型焦生产系统－以无烟粉煤为主要原料的型煤竖炉炼焦技术，并对其社会效益和经济效益进行初步评估。该型焦技术是以无烟粉煤为主要原料（占70％），添加少量烟煤及粘合剂生产型煤，型煤进入连续运行的竖炉炼焦，所产煤气经净化后用作焦炉及型煤干燥的热源。其炼焦生产全过程密闭、连续、焦化时间短、无污染，产品块度及挥发分等主要指标调整灵活。

A Cleaned Production Technology of Anthracite Formed Coke

A vertical coke oven technology is adopted to produce cleaned formed coke using fine anthracite as raw material. The economic and social benefit are estimated. At first, anthracite briquette is made by 70 % fine anthracite and 30% of bituminous and binder. And then, the anthracite briquette is put into vertical coke oven to produce continuously the formed coke. The coke oven gas is purified and then used as fuel in coke oven and briquette drying. The total process is airtight, continued, without pollution. Coke time is shorter. Product size and volatile content can be adjusted.
