An initial part of the fuel is fed, via a first feeder (4) with an injector plate (15), to the main pipe (10) where it is mixed with oxygen-enriched primary gas (PG) inside at least one pre-mixing zone (VMZ). The concentration of the fuel in the pre-mixture (VM) thereby formed is such that the pre-mixture lies outside the ignition limit. The pre-mixture is fed to a final mixing zone (EMZ) where it is mixed with the remaining fuel (RB) and/or with oxygen-enriched secondary gas (SG), via a second feeder (6) inside a housing (10). The resulting final mixture (EM) is fed to a subsequent combustion zone (VZ) to which an oxygen-enriched tertiary gas (TG) is fed the combustion zone. |
