To reduce its size and improve exhaust emission property, it is effective for spray type combustor to increase burning velocity by promoting such as fuel evaporation, diffusion, mixture of fuel and air. Excessive swirl inhibit the mixture in centrifugal direction of fuel and air to deteriorate combustion condition. This paper reports the coexistence of high load combustion and emission reduction experimentally confirmed having shorter flame length, compared to swirl type combustor, by making many air injection holes along combustion cylinder axis which causes creating small turbulence.
