    Abstract: Premixed combustion systems for gas turbines offer the possibility of low-pollution, high-combustion efficiency and good temperature distribution. They form a basis by which other well-mixed combustion systems may be assessed. The ultimate objective of this work is the development of nonpremixed rapid mixing combustion systems. Different geometries of baffle flame stabilizers are tested to study the influence of recirculation zone size and number of recirculation zones on flame stability, combustion efficiency and NOx . The results show that the flame stabilizer geometry has a major influence on combustion efficiency and flame stability but a lesser influence on NOx . Optimum equivalence ratios are identified for good combustion efficiency and low NOx at simulated low and high-power engine conditions.
