| Abstract: |
| For duplex atomizers, satisfactory atomization of pilot fuel could not be obtained at low fuel flows, when main passage does not operate, causing difficulties in ignition and combustion. Experiments show that pilot fuel atomization could be effectively improved by supplying main passage with pressurized air. The results are useful for operation of stationary gas turbine and for aero-derivative gas turbine using low quality fuel. |
