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.
