Research Progress on Lean Premixed Prevaporized Combustor
The lean premixed prevaporized(LPP)combustor is the most representative advanced gas tur-bine combustor at present,which has great potential in realizing ultralow emission.Based on the working principle of LPP combustor,the research status of flow field organization method in combustor at home and overseas is introduced,and the difference in fuel and air matching scheme is analyzed.The research progress of combustion and emission characteristics of LPP combustor is sorted out from three aspects,such as the main parameters of swirler,fuel atomization and mixing method,fuel allocation method.The shortcomings in the existing research are pointed out.Based on the existing research content and techni-cal development trend,it is believed that LPP combustor should be developed in the direction of low re-sistance and pressure loss,ultralow emission and high combustion stability.
