摘要
讨论了某重型燃气轮机(E级)燃烧室燃料喷嘴组雾化特性试验研究结果.应用美国TSI公司LDV/PDPA系统测得不同压力下喷嘴组雾化粒度及分布,应用软件识别方法测得喷嘴组喷雾锥角.试验结果表明:喷嘴组雾化粒度对压力变化敏感,当压力由0.4 MPa升高到1.2 MPa时,粒度由23.22μm降低到10.11μm,而雾化锥角则由73.5°降低到69.5°.试验数据为喷嘴组的设计改型提供了可靠的依据.
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.
