| Abstract: | Lignite dehydration is a base prior to the use of lignite.Based on the theory and practice of microwave radiation drying,we have a study about lignite from eji,Inner Mongolia.We study how factors such as the drying time.coal particle size.Microwave power and Heating method can influence the dewatering upgradation of lignite.The results show that on the condition of drying time 5min,microwave power at 720W,coal particle size of 3 to 6,intermittent heating,the dehydration rate of the water content could be reached 64.10%. |
