Abstract
To improve slag quality, on a fired grate, at the end of the main combustion process, where burnable fractions are still present in addition to slag components which are already forming, the burnup rate or burnup intensity is changed by varying the primary air rate in sequential time sections, the time sections preferably being in a ratio of 1:1 and the reduced primary air rate being 50 to 70% of the standard primary air rate.
