精煤水份是洗煤厂一项重要指标。众所周知,精煤水份高,不仅炼焦时使焦炉温度下降,导致焦炉生产率降低,炉龄缩短,而且易于在运输过程中毁坏车箱,在严寒地区冬季还造成冻结,给装卸车带来很大困难。同时还都要多耗费能源,做无用功,造成不必要的浪费。因此,为合理利用能源,避免运输隋性物质,满足用户和运输的要求,设法降低精煤水份是十分必要的。
Clean coal moisture is an important indicator of coal washing plant. It is well-known that high moisture of coke not only reduces the temperature of the coke oven when coking, resulting in lower coke oven productivity, shortened furnace age and easy destruction of the trunk during transport, but also brings about freezing in winter in severe cold areas, Big difficulty. At the same time, we must also spend more energy, doing useful work, resulting in unnecessary waste. Therefore, in order to make rational use of energy, avoid the transportation of inert substances and meet the requirements of users and transport, it is very necessary to try to reduce the water content of clean coal.
