Reformer Burner
Reformer Burner
The GIAP’s mixing burner may be used in existing Ammonia Plants АМ-70, АМ-76, ТЕС, Chemico, CLE, АМ-600, ENSA, as well as those under construction and recently built using Linde, Uhde, Haldor Topsoe, KBR technologies. Moreover, the GIAP’s mixing burner can be used in ammonia plants incorporating secondary methane reforming.
The unique design of the GIAP’s reformer burner ensures uniform gas flow velocity and temperature profiles upstream of the catalyst, which adds to its capacity and life. Gas flow is straightened by means of a gas distributor plate installed in the reactor neck annulus below the feeding nozzle. After the distributor plate, the gas passes between the mixing tubes and farther through the lower grille before blending with steam/air mix. Together with the space shaped by the neck and steam/air mix distributor, the grille system ensures uniform gas flow between the steam/air mix distributor tubes at the neck outlet. The steam/air mix is fed to the distribution chamber with tubes welded inside its funnel and sphere-shaped section. A perforated plate is provided to equalize steam/air mix velocities across the distribution chamber cross section.
Due to efficient flow mixing, the GIAP’s mixing burner operates with a shorter flame, which, along with minimized flow resistance:
- Reduces adverse thermal and aerodynamic effect of the flow on upper catalyst layers and overlying ceramic tiles.
- Improves methane conversion and catalyst life due to more uniform temperature profile
- Ensures steady flame.
The use of refractory materials and surface protection guarantees the specified burner life (10 years or more) amid high temperatures in a corrosive environment.
