The lean premixed prevaporized (LPP) combustor is the most representative advanced gas turbine 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 ana-lyzed. 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 re-search are pointed out by analyzing the flow field structure, fuel and air mixing process, flame shape and emission characteristics of combustor. Based on the existing research content and technical development trend, it is believed that LPP combustor should be de-veloped in the direction of low resistance and pressure loss, ultralow emission and high combustion stability.
