摘要:
In a non-evaporating dehydration of brown coal, the coal is crushed and classified into lumps and fine particles. The lumps of coal are subjected to a non-evaporating dehydration in which waste water is produced. The waste water is contacted with the fine particles of coal so that components which affect the COD value of the water are absorbed by the coal particles. The coal particles are then burnt to produce saturated steam which is used in the non-evaporating dehydration.
