电厂粉煤灰是一种数量巨大,用途广泛的工业废尘,随着科学的发展,人们对粉煤灰特性的认识在日益深入,应用领域不断扩大,利用量在逐年提高,经济效益日见增加。近年来我们曾对粉煤灰的形成机理,矿物组成,化学成份,及物、化性能等方面作了研究,在此基础上拟对粉煤灰的颗粒组成、分选方法及综合利用途径作一初步介绍 Power plant fly ash is a huge quantity, a wide range of industrial waste, with the scientific development, people’s understanding of the characteristics of fly ash increasingly in-depth, applications continue to expand, the use of increased year by year, the economic benefits of the day increase. In recent years, we have on the formation mechanism of fly ash, mineral composition, chemical composition, and properties, and other aspects of the performance were studied on the basis of the proposed fly ash particle composition, sorting methods and comprehensive utilization of ways A preliminary introduction
