粒径对飞灰比电阻及介电特性的影响
Effect of particle size on resistivity and dielectric property of fly ash
摘要
Abstract
The resistivity and dielectric property of fly ash play an important role in enhancing the dust re-moval rate and fly ash recirculation rate.To focus on this,fly ash samples were collected from two domestic power plants and then sieved into different particle sizes.By using powder resistivity detector and vector network analyzer (VNA),the effects of fly ash particle size on its specific resistivity and dielectric property were studied.The results show that,for the fly ash with carbon,the resistivity and dielectric loss of the fly ash had no obvious changing rule with the particle size.While for the decarbonized fly ash,the specific re-sistivity decreased and the dielectric loss of fly ash increased when the particle size decreased.关键词
