一种操作简单并确定干燥煤配比准确的炼焦方法:获取配合煤试样;对部分配合煤试样进行干燥;确定经干燥后的配合煤试样配合比例;对检测值≤原湿煤粉尘检测值,且测量的堆比重值低于原湿煤的堆比重值12%的不同比例干湿配合煤进行装炉炼焦试验.本发明与现有技术相比,本发明能在不改变现有生产工艺,不对现用焦化生产带来不利影响,不仅减少了干燥煤量,且使试验效率提高,操作简单并确定干燥煤适宜控制比例准确,并且通过试验确定干燥煤比例后,生产可按该比例稳定干燥煤配量,与现场结合度高,生产波动小,对指导现场生产具有显著意义。

A coking method with simple operation and accurate determination of dry coal ratio: obtaining mixed coal samples; Dry some blended coal samples; Determine the mix proportion of dried coal samples; Compared with the prior art, the invention can not only reduce the amount of dry coal, but also improve the test efficiency without changing the existing production process and bringing no adverse impact on the production of existing coking, The operation is simple and the appropriate control proportion of dry coal is accurate. After the proportion of dry coal is determined through the test, the production can stabilize the proportion of dry coal according to this proportion, with high combination with the site and small production fluctuation, which is of great significance to guide the site production.
