Taking the dry direct blowing pulverizing system in Huaneng Jiutai Power Plant as the example

the evaporated water recycling experiment for lignite was carried out.The feasibility of recycling the evaporated water during lignite drying process by flue gas was discussed.Moreover

water quality analysis was performed on the collected recycled water.The results show that

using flue gas to dry the lignite and recycle the evaporated water is feasible;after simple treatment

the recycled water can be applied in desulfurization system;this method reduced the water consumption

indicating the economic benefit is dramatic.
