Abstract
Secondary air injection orifices in an experimental cantype combustion chamber using a vaporizer tube for fuel injection are modified to produce turbulent mixing of the excees air with the combustion products. The results of this investigation are conpared with those of a previous project and the following results are noted: 1. Burner thermal efficiences are very slightly reduced. 2. Mixing is thorough, as determined by flame patterns and temperature data. 3. Even temperature and velocity profiles are obtained at the exit cross-section of the combustion chamber. 4. This type of quenching would permit shortening of a 20-inch combustion chamber "by at least 2-inches, or 10%. 5. Total pressure losses were doubled, increasing from an average value of 5.6% to 11.3% of the inlet total pressure.
