超净精煤灰分测定的因素的影响的探讨

he orthogonal test design was used to arrange sequential experiments to study the effects of the main factors affecting ash determination of ultra-clean coal. The interactions between the factors were tested in additional experiments. Comparing flocculation-flotation clean coal and ultra-clean coal, the study described distinctive features of ultra-clean coal ash. Summarize the law of ultra-clean ash determination, provide a guidance for the ultra-clean ash determination.
