Abstract: A process for the production of synthesis gas by partial combustion of a hydrocarbon feed using a burner with a plurality of coaxial channels, the method comprising the following steps: supplying a non-gaseous hydrocarbon feed using at least one of the plurality of coaxial channels; supplying a gaseous hydrocarbon feed using at least one of the plurality of coaxial channels; supplying an oxidizer gas using at least one of the plurality of coaxial channels; separately supplying a moderator gas using at least one of the plurality of coaxial channels; arranging the at least one channel supplying the non-gaseous hydrocarbon feed between two adjacent channels among the plurality of coaxial channels, wherein the two adjacent channels both supplying a flow containing the gaseous hydrocarbon feed or respectively supplying a flow containing the gaseous hydrocarbon feed and a flow of the moderator gas.

Abstract: The invention is directed to a burner for the gasification of a solid fuel, comprising a burner front having an opening for discharging a solid fuel, wherein the opening for discharging the solid fuel is fluidly connected to a central passage way and wherein the central passage way has a downstream part wherein the diameter of the passage way increases over a first length and subsequently decreases over a second length terminating at the burner front and wherein inside the downstream part of the central passage way a hollow member is positioned, and wherein the hollow member has an internal increasing diameter and inner decreasing diameter aligned with the increasing and decreasing diameter of the hollow member and wherein the connecting conduits have a discharge opening positioned in the diverging part of the hollow member.

Abstract: Process, reactor and burner for the gasification of a hydrocarbon fuel. The burner comprises coaxial channels for the separate supply of an oxidizer gas, a hydrocarbon fuel and a moderator gas. A coaxial channel with the smallest width is bordered by a separating wall with at least one gas exchange. The gas exchange passage can for example be formed by a retracted end of the separating wall and/or by openings in the separating wall.

Abstract: The invention is directed to a burner comprising (a) a burner pipe, (b) mixing means arranged in the burner pipe for mixing an oxygen-containing gas and a fuel gas and for discharging the resulting gas mixture within the burner pipe; and (c) stabilising means downstream of the mixing means in the centre of the burner pipe, wherein the stabilising means comprises a conically shaped body which widens in flow direction.

Abstract: A burner includes a burner front having annular and central openings. The annular opening, for discharging a solid fuel, fluidly connects to a central passage way. The central opening, for discharging an oxygen containing gas, fluidly connects to an annular passage way for passage of oxygen positioned co-axial with the central passage way. The central passage way has a downstream part and a diameter that increases over a first length and subsequently decreases over a second length terminating at the burner front. Inside the downstream part a hollow member is positioned which is closed at one end and has an opening at or near the burner front, and has increasing and decreasing diameters aligned with the increasing and decreasing diameters of the central passage way forming an annular passage. The hollow member fluidly connects with the annular passage way for the oxygen containing gas via one or more connecting conduits.
