The invention relates to a burner, particularly for the gasification of solid carbonaceous materials by partial combustion. The burner comprises a central channel (2) and at least one coaxial channel (6). The channels (2, 6) are defined by concentric walls (3, 5) having free downstream outer ends profiled to define an annular slit (10) forming a discharge end of the coaxial channel (6) and converging towards an adjacent discharge end of the central channel (2). The burner (1) is encased by a cooling jacket (14) and comprises a front face (21) with double walls spaced by one or more baffles (28) defining a coolant flow path operatively connected to the cooling jacket (14). The cooling jacket (14) has an upstream section (14A) and a transitional section (25) narrowing down to the front face (21) having a smaller outer diameter than the upstream cooling jacket section.
A burner comprising a central channel and at least one coaxial channel surrounding the central channel, the channels leading from an upstream supply side to a downstream discharge end, the central channel and the coaxial channel being defined by concentric inner and outer walls having free downstream outer ends profiled to define an annular slit forming a discharge end of the coaxial channel and converging towards an adjacent discharge end of the central channel, the burner being encased by a cooling jacket and comprising a double walled front face, the double walls of the front face being spaced by one or more baffles defining a coolant flow path operatively connected to the cooling jacket wherein the cooling jacket has an upstream section and transitional section narrowing down to the front face having a smaller outer diameter than the upstream section of the cooling jacket.
