为提高配煤挥发份,我厂今年进行了四个配煤方案的试验,所得焦炭质量良好。考虑到国家对今后几年用煤基地定点的要求,需要继续进行生产试验,以求得合理用煤的方案。同时,为了配合平顶山煤田的调查,对今后使用平顶山煤提供配煤参考数据,在最后三个方案中进行了模拟试验,并与去年的试验结果作了多方面的比较。 (一)试验情况试验在2号焦炉进行,自2月27日至3月24日共计26天,除第七方案生产二天外,其他皆生产了3～5天,焦炉按正常生产制度进行,周转时间规定为18小时,主要采用高炉煤气加热(混入少量焦炉煤气),规定之标准温度,机侧为1180～1185℃,焦侧为1225℃。过去2号炉炉头温度一直偏低,尤其在机侧炉头温度
In order to increase the volatile content of coal blending, our factory carried out the experiment of four coal blending schemes this year and the quality of coke obtained was of good quality. Taking into account the country’s fixed-point requirements for the next few years with coal bases, the need for continued production tests in order to obtain a reasonable program of coal. In the meantime, in order to cooperate with the investigation of Pingdingshan coalfield, the coal blending reference data for Pingdingshan Coal will be provided in the future. The simulation experiments are carried out in the last three schemes and compared with last year’s test results in many aspects. (A) Test conditions Test in No.2 coke oven, from February 27 to March 24 a total of 26 days, in addition to the seventh program for two days, the other are produced 3 to 5 days, according to the normal production of coke oven system , The turnaround time is 18 hours. The main use of blast furnace gas heating (mixed with a small amount of coke oven gas), the standard temperature, the machine side of 1180 ~ 1185 ℃, coke side of 1225 ℃. In the past furnace No. 2 furnace temperature has been low, especially in the machine side burner temperature
