ABSTRACT:
A burner for the partial combustion of a finely divided solid fuel in a combustion zone, comprising a central channel for finely divided solid fuel, an annular channel for free-oxygen containing gas, substantially concentrically surrounding the central channel. The annular channel is provided with primary, inclined outlet means for directing high velocity free-oxygen containing gas into the outflowing solid fuel during operation and secondary outlet means 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.
