Research Abstract

Micro gas turbines (MGT) for small-scale distributed generation systems are expected to play a major role in the future energy security with lower environmental impacts. However, small combustors for MGT are operated at low Reynolds numbers with a wide range of partial load, where it is difficult to maintain stable and clean combustion. In the present study, a methane-air coaxial jet flame, which is commonly used in gas turbine combustors, is actively controlled with miniature jet actuators installed on the inner surface of the coaxial nozzle. The periodic radial miniature jet injections are realized by using a rapid-response pneumatic servo-valve. By manipulating the large-scale vortical structures and the associated methane-air mixing with the actuators, it is demonstrated that flame holding and exhaust gas characteristics are drastically improved under different load conditions.
