Method of defining dispersed composition of powder material by uniflow cyclone stage

Abstract

At powdered burning of fine-dispersed solid fuel the behaviour of particles of different size in dust- and ash extraction devices are not the same. To make a justified choice and correct estimation of gas purification systems operation the data about dispersed composition of the extracted product are necessary. The technique allowing operative calculation of fractional composition has been developed. The obtained results and the data of dispersed analysis obtained by the other method are compared. Stable solution showing the possibility of using the method in defining dust dispersity from 10 to 50 mkm is obtained.
