| Description | The first outcome of the research is the explanation of why the addition of different fuel blends in gas turbine combustors leads to initiation of thermoacoustic oscillations at different operating conditions. The current findings demonstrated that the triggering of the oscillations occurs due to the interaction between the flame and the flow (a hydrodynamic effect) rather than the widely accepted belief that the acoustics of the combustor determine the initiation of the oscillations. As a consequence, the research established the way that the flame-flow interaction occurs during the variation of the supplied fuel and, in this way, provided a new hydrodynamic scaling of the operating conditions at which thermoacoustic oscillations are triggered. Once the oscillations are triggered, then the acoustics determine the frequency of the observed oscillations. This finding has generated new ideas for control of the initiation of the oscillations. A second outcome of the research was the development of a novel sensor that can monitor the components of fuel blend real time and, as a consequence, establish the variability of the supplied fuel. This sensor can be integrated on a power plant to assist optimised operation for reduced emissions, including NOx and CO, which limit the flexible operation of gas turbine combustors. |
