<p>A process for the manufacture of synthesis gas by reacting oxygen-containing gas, applied as oxidizer and gaseous hydrocarbon-containing fuel in a reaction zone of a non-catalytic gas generator comprising the steps of injecting the said fuel and the said oxidizer into the reaction zone through a multi-orifice (co-annular) burner comprising arrangement of n separate passages or channels coaxial with the longitudinal axis of said burner, wherein n is an integer >/=2 (2, 3, 4, 5 . . . ) wherein the (n-1)th passage is the inner passage with respect to the nth passage, measured from the longitudinal axis of the said burner, and wherein gaseous hydrocarbon-containing fuel and, optionally, a moderator is passed through one or more of the passages, but at least through the nth (outer) passage whereby at least one passage remains; oxidizer and, optionally, a moderator, is passed through one or more of the remaining passages, but at least through the (n-1)th passage. In any two adjacent passages in which oxidizer is passed through the one passage, and gaseous hydrocarbon-containing fuel is passed through the other passage, the said oxidizer has a higher velocity than said hydrocarbon-containing fuel.</p> |
