摘要: 论述了航空衍生燃气轮机双燃料低污染燃烧技术的研发过程,总结了所采用的促使该技术成功发展的重要技术要点,对双燃料燃烧室可以工作的燃料-空气比的范围、燃料-空气比对CO和NOx排放的影响及过渡工况设计给予了论述,并全面总结了双燃料低污染燃烧室设计上的考虑因素.通过对多种贫燃预混的双燃料-空气模的研究设计以及长期地、持续地进行研发及燃烧试验,结果表明:设计的双燃料燃烧室在50%~100%工况范围每一点都可满足低污染要求.所研发的低污染燃烧技术以及过渡工况的设计都切实可行,可以直接用于航空发动机型号产品.Abstract: Development of aero-derivative gas turbine dual fuel low emission combustion technology was studied, and major technical approaches to the success of the development were summarized. Range of fuel-air ratio of dual fuel combustor, effect of fuel-air ratio on CO and NOx emission, and design of transition operation were discussed; considerations in designing dual fuel low emission combustion were summarized comprehensively. By study of a variety of dual fuel lean premixed fuel-air modules, as well as long-term and lasting research and development on combustion test, the result shows that, the designed dual fuel combustion can meet the requirements of low pollution in the range of 50%-100% operation, and such low emission combustion technology and design of transient operation are practicable and can be directly used into the typical product of aero-engine.
