What factors can influence rotary kiln burner working

What factors can influence rotary kiln burner working

Pulverized coal volatiles: pulverized coal with low volatiles ( 15%) tends to form rotary kiln burner flames with long black heads, short high temperature parts and high local flame temperatures. Although the coal powder with high volatiles ( 30%) is quick to ignite, it takes a certain time for volatiles fractionation and combustion, and the
