Kiln burners efficiency improvement with traditional and future resources.

A burner with 100% solid secondary fuel rate looks very tempting at first sight. A closer look raises several questions that must be answered, though. As long as there are no cost effective ways of preparing the SSF (classification of secondary fuel, high efficient grinding process), the economic benefit compared to traditional burners with e.g. 80% SSF and 20% petcoke/coal is doubtful and needs to be further investigated.
