Atomization systems in both straight through flow and reverse flow combustion systems requires high pressure fuel pump, to guarantee fine mist. This is the main consideration for the development of alternative fuel extraction systems, namely vaporizer system. Design of combustion chamber with vaporizer system is done with analytic and numeric method. From available reference conceptual design and initial sizing of combustion chamber can be established. From empiric method casing dimension and liner dimension can be roughly estimated. To further design the combustion chamber numerical simulation is used to know gas behavior in combustion chamber. With the information from numerical simulation combustion chamber than optimized. Numerical simulation was done with commercial CFD. After design process finished, next step are combustion chamber model for experiment. In this proposal experiment are optional and planned to be done at the end of the year. Experiment will be held after redesigning combustion chamber, making combustion chamber model and setting experiment. From analytic method, combustion chamber diameter, hole diameter and hole distribution can be determined. Then a numerical analysis is carried out to determine whether swirler is needed or not. Swirler was varried 45 degrees and 60 degrees and fuel injector are varied from 4 to 8. Finally the best combustion chamber are straight through combustion chamber with 60 degree siwrler angle and 8 fuel injector.
