A partial combustion process for a particulate solid fuel and a burner for carrying out such a process is disclosed wherein the particulate fuel is injected into a premix chamber along with primary gas streams to support combustion and secondary gas streams to form a shroud of gas around the fuel as the mixture of fuel and gas leaves the pre-mix zone through a converging-diverging nozzle to enter the combustion zone.

A process for the gasification of a solid particulate fuel by partial combustion, which comprises the steps of: injecting into a pre-mix zone along a central flow axis a stream of transfer fluid having the particulate fuel disposed therein to form a central flow stream; impinging a plurality of primary oxygen containing streams upon the central stream of transfer fluid having the particulate fuel disposed therein at an angle in the range of 30°to 60°relative to the central flow axis and having a velocity exceeding the velocity of the central stream; and injecting a plurality of secondary oxygen containing gas streams into the pre-mix zone at a velocity in excess of the fuel stream for forming a shroud around the central stream as the mixture of fuel and gas streams flow from the pre-mix zone through a converging-diverging nozzle having a throat section into a combustion zone.
