A process for the manufacture of synthesis gas by reacting oxygen-containing gas (oxidizer), moderator gas and a liquid, hydrocarbon-containing fuel in a reaction zone of a substantially non-catalytic gas generator comprising the steps of simultaneously injecting the said fuel and said oxidizer into the reaction zone through a multi-orifice (co-annular) burner comprising an arrangement of n separate passages or channels coaxial with the longitudinal axis of the said burner wherein n is 3 or more. The fuel is passed through one or more of the passages advantageously at a velocity or velocities between 2 and 40 m/s, whereby at least 2 passages remain, the oxygen-containing gas is passed through one or more of the remaining passages advantageously at a velocity or velocities between 20 and 140 m/s, whereby at least 1 passage remains, the moderator is passed through one or more of the remaining passages advantageously at a velocity or velocities between 5 and 140 m/s, in such a way that any two passages through which the fuel respectively the oxygen-containing gas are passed are always separated by at least one passage through which the moderator is passed. |
