我厂简易二号焦炉自3月上旬施工,5月2日正式投入生产。几个月以来,生产安全正常。结焦时间逐步缩短,由开工时26—28小时到7、8月份缩短到14—16小时,焦炭产量显著提高,5月份产量为292.42吨,6月份469.34吨,7—8月份上升到560—620吨,超过原设计定额15%,出焦率达到72～74%,焦炭质量由于加强了煤的洗选及粉碎工作,因而不断地改善,焦炭灰份由过去16—22%,降低到12—14%,硫份由0.8—0.9%降低到0.6—0.7%,焦炭强度随着炉温的正常而大大提高了。此外,还可以回收煤焦油,回收率为2.7—3.0%,自焦炉开工至8月份以来,已回收煤焦油80多吨。7月以来,着手改善劳动组织,健全生产制度,加强技术学习,吸收外地经验,进一步改善调温工作,因而炉温显著提高,一般达到1050—1100℃,在此基础上开始进行不烧小灶试验工作,到8月4日全部取消小灶,煤气完全能够
I plant simple two coke oven construction from early March, May 2 formally put into production. Production safety has been normal for months. Coking time gradually reduced from the start of 26-28 hours to 7,8 shortened to 14-16 hours, coke production increased significantly in May for the production of 292.42 tons, 469.34 tons in June, July-August rose to 560-620 Ton, more than the original design quota of 15%, the rate of 72 ~ 74% of the coke, coke quality as a result of strengthening coal washing and crushing work, and thus continue to improve, from 16-22% of coke ash, down to 12- 14% and the sulfur content decreased from 0.8-0.9% to 0.6-0.7%. The coke strength increased greatly with the normal furnace temperature. In addition, you can also recover coal tar, the recovery rate of 2.7-3.0%, since the coke oven started to August, has recovered more than 80 tons of coal tar. Since July, efforts have been made to improve the labor organization, improve the production system, strengthen technical learning, absorb foreign experience and further improve the temperature control work. As a result, the furnace temperature has been significantly raised, generally reaching 1050-1100 ° C, Work, to the abolition of small stoves on August 4, gas is fully able to
