Beschreibung
Zusammenfassung:	A burner of the reactor mix type for the partial combustion of a finely divided solid fuel in a combustion zone, comprising a central channel (11) for finely divided solid fuel, an annular channel (12) for free-oxygen containing gas, substantially concentrically surrounding the central channel (11), said annular channel (12) being provided with primary, inclined outlet means (14) for directing high velocity free-oxygen containing gas into the outflowing solid fuel during operation and secondary outlet means (13) around the primary outlet means for conveying shielding low velocity free-oxygen containing gas to the combustion zone. The invention further relates to a process for the partial combustion of a finely divided solid fuel, wherein one or more burners of the above type are applied.
