炼焦煤和动力煤经洗选后。精煤中必然会带一部分水分,如果不很好脱除,对选煤厂和有关工业部门均会造成很大影响。精煤水分高,选煤厂装车线路既不卫生又不安全,增加运输量,在北方还会造成卸车困难,影响车辆周转。如鞍钢每年超水分运量为27万吨,占用车辆5400辆,运输水分量达14700万吨公里,以运输一吨公里0.01元计算,鞍钢每年超水浪费运输力达147万元。故鞍钢要求精煤出厂水分不得超过10%。我厂今年精煤计划水分为12.0%,离此要求还有一定距离,因此选煤厂应尽力设法降低精煤水分,以满足用户的要求。
Coking coal and steam coal after washing. Coal will inevitably bring some water, if not removed, the coal preparation plant and the relevant industrial sector will have a significant impact. High coal moisture, coal preparation plant loading line is neither hygienic nor safe, increase the volume of transport, in the north will cause unloading difficulties, affecting vehicle turnover. For example, Anshan Iron and Steel annual super-water transport capacity of 270,000 tons, 5,400 vehicles occupied, the transport of water amounted to 147 million kilometers to transport one ton kilometer 0.01 yuan calculation, Anshan Iron and the annual water transport waste amounted to 1.47 million yuan. Therefore, Anshan Iron and Steel Co., Ltd. requires the factory moisture shall not exceed 10%. Our plant this year plans to clean water 12.0% moisture, there is still some distance from this requirement, so the coal preparation plant should try its best to reduce the clean coal moisture to meet user requirements.
