The present invention relates to a device and a process for manufacturing synthesis gases through the combustion, under lack of oxygen, of a hydrocarbon fuel by use of a gaseous oxidizer, the device comprises primary injection means (2) producing, following an axis (14), a jet of fuel and of part of the oxidizer in a combustion chamber of a reactor, said jet comprising a main flame substantially originating at the level of the primary injection means (2) and extending from the primary injection means. The device also includes secondary injection means for injecting a complementary amount of oxidizer into the combustion chamber, the secondary injection means being arranged to direct the complementary amount of oxidizer into the jet at a distance from the primary injection means.
A device for manufacturing synthesis gas through the combustion, under a lack of oxygen, of a hydrocarbon fuel with a gaseous oxidizer, said device comprising a reactor having a combustion chamber and a primary injection means for producing a jet of the fuel and a portion of the oxidizer in the combustion chamber of the reactor, said jet having an elongated axis and forming a main flame substantially originating at an outlet level of the primary injection means and extending from the primary injection means along said axis and secondary injection means for injecting a complementary portion of the oxidizer into said combustion chamber, said secondary injection means being arranged to inject the complementary portion of oxidizer into said jet at a distance spaced from the outlet level of said primary injection means.
A device for manufacturing a synthesis gas through the combustion, under lack of oxygen of a hydrocarbon fuel with a gaseous oxidizer, said device comprising a reactor having a combustion chamber and primary injection means for producing at least one jet of the fuel and a portion of the oxidizer in the combustion chamber of the reactor, said at least one jet having an elongated axis and forming at least one main flame substantially originating at an outlet level of the primary injection means and extending from the primary injection means along said axis and secondary injection means for injecting a complementary portion of the oxidizer into said combustion chamber, said secondary injection means being arranged to inject the complementary portion of oxidizer into said at least one jet at a distance spaced from the outlet level of said primary injection means and to form a secondary flame spaced from the at least one main flame;
A process for manufacturing synthesis gas through the combustion, under a lack of oxygen, of a hydrocarbon fuel with a gaseous oxidizer which comprises injecting the fuel and a part of an oxidizer in the form of a jet having an elongated axis into a combustion chamber of reactor via a primary injection means, said jet forming a main flame originating substantially at an outlet level of the primary injection means and extending from the primary injection means, and injecting a complementary amount of oxidizer through at least one outlet of secondary injection means spaced from the outlet level of the primary injection means and located to direct a complementary amount of oxidizer into said jet, the complementary amount of oxidizer and the fuel forming at least one secondary flame spaced from the main flame.
