Effects of sludge on the ash fusion behaviors of corn stalk and its modification mechanisms

The ash fusion behaviors of corn stalk (CS) and its variation mechanisms by two sludges [municipal-water sewage sludge (MW) and textile dyeing sludge (TD)] additions in an oxidizing atmosphere were investigated. Increasing the MW mass ratio led to an initial slow rise in the ash fusion temperatures (AFTs), but then they slowly decreased. The four characteristic temperatures for CS-TD all gradually increased as the TD proportion rose. An increase...
