Abstract: The atomization behavior of the fuel injector group in the combustion chamber of a Grade E heavy-duty gas turbine was experimentally investigated and the results were discussed. Applying the LDV/PDPA system supplied by TSI Co. to measuring the atomized particle size from the fuel injector group and its distribution under different pressures, the spray cone angle was given by relevant recognition software. The results showed that the atomized particle size is sensitive to pressure. For instance, the particle size decreases from 23.32 to 10.11μm with the pressure increasing from 0.4 to 1.2 MPa, whereas the spray cone angle decreases to 69.5° from 73.5°. Those experimental data provides a reliable basis for the design and R& D of injector group.
