摘要
Abstract
Lignite dewatering based on recovery of water and heat can significantly reduce water and energy consumption in the drying unit. The existence states of water in lignite are introduced,and the advances in recovery and utilization of water and heat from lignite dewatering are reviewed. Specially, drying technologies in the light of drying with flue gas,drying in fluidized bed with steam,microwave drying and mechanical/thermal pressurizing are presented. The principle for selection of lignite dewatering process and water recovery system is discussed. During recovery of water resource, considerations of lignite dewatering process,drying temperature,drying medium,heat recovery technology,and linkages of various processes should also be included. The process,which integrates heat exchangeand water purification into lignite dewatering would be a promising research and application topic in the future.关键词
