It has generally been known that Carbon-Flower is phenomenon that scale adheres and deposits on the outskirts of fuel atomizer when heavy fuel oil is used.
This phenomenon is supposed to occur by the adherence, carbonization and gasification of unburned heavy fuel oil drops.
This phenomenon has been reported in the papers entitled “Carbon Sticking in the Diesel Engine”and“Fouling in Fluidized Bed Coal Combustion”. However, the phenomenon was not fully understood because of the insufficience of informations. The problem is that there are a lot of residual carbon and various metals in the heavy oil, and the behavior of spray flow is not clear as well as the temperature around the adhering and accumlating point is not obvious.
This study has used various measuring methods in order to grasp the formation and growth mechanism of Carbon-Flower generated in steady spray combustion at atmospheric pressure.
