When the main nozzle adopts the structure device, the equivalence ratio is generally symmetrically distributed along the central axis of the main nozzle, and when the main nozzle is designed, if the equivalence ratio of the nozzle close to the on-duty (as shown in figure 2a), the equivalence ratio of the area close to the wall surface of the flame tube is increased, so that the area of the wall surface of the flame tube is over-heated; if the equivalence ratio close to the on-duty nozzle is low (as shown in fig. 2b), the ignition action of the on-duty nozzle to the main nozzle is not easy to realize, so that the combustion of the main nozzle is insufficient; FIG. 2c is a more desirable equivalence ratio distribution, but this situation often requires enhanced blending by increasing the swirl strength of the nozzle, which causes recirculation zones downstream of the nozzle, resulting in increased NOx emissions.
Fig. 3 is a structure in which the outlet of the main nozzle is circular, which has a problem in that the cooling difficulty is large. FIG. 4 is a fan-shaped structure of the main nozzle outlet, which has a small cooling range and requires a circular fan adapter section at the main nozzle in terms of structural design.
