17 axis direction of fuel nozzle ports is uniformly distributed for one group at 12.5 ° of angles around circumferentially every 2 of 17 central shaft of liquid fuel spout at 30 ° of angles
10 gaseous fuel outlets 15 spray, into combustion space, ensure good combustion effect.At this point, liquid fuel road feeds pressure
Contracting air purge and meanwhile nozzle body is cooled down, prolong the service life.
As shown in Figure 1, prevent carbon distribution air cooling component by the front fin 32 of heat-insulated inner cover 7 and nozzle body 8 with it is finned
Runner 31 is constituted, and the two is attached by the way of welding.The advantage of this fin structure is to improve nozzle arrangements intensity
I.e. non-deformability while enhanced heat exchange, keep nozzle interior low temperature, prolong the service life.Cooling air passes through 6 normal direction
Anti-carbon deposition air intake 27 enter to nozzle body 8 finned runner 31 and heat-insulated inner cover 7 constitute free air space, finally by
16 spouting formation thermal insulation protection gas mould of cooling air outlet, prevents carbon distribution from being formed.
It uses liquid fuel when starting and slow train operating mode are run using the gas turbine of the double nozzle, passes through and assist mist
Change air road it is actively air-supplied, it can be achieved that under the conditions of single liquid fuel road liquid fuel good atomization, improvement lights a fire at this time
Performance and efficiency of combustion avoid additional volume subsystem；When high operating mode is run, pass through liquid fuel swirling flow atomizing component and sky
Gas assists the effective of swirling flow atomizing component to combine design, and negative pressuren zone, combustion chamber can be formed in exit after the strong eddy flow of liquid fuel
Interior air can out of burning chamber shell under differential pressure action automatically into air-assisted atomization eddy flow component, to having sprayed and
The liquid fuel of atomization carries out reinforcing atomization by the shear action of air-flow, realizes " self-priming " air-assisted atomization, further
Improve efficiency of combustion.Effective combination that liquid fuel is well atomized when being run by slow train operating mode and high operating mode, and take into account
The global design that fuel gas uses, realize gas turbine full working scope multi fuel Effec-tive Function, keep gas turbine it is small,
Light-weight innate advantage widens the application range of gas turbine, realizes the rational and efficient use of the energy.
