The knowledge of fluid dynamics and combustion processes in power generation is of the greatest impact to the development of new products that will allow the implementation of alternative energies to the current economy. A reduction in fossil fuel consumption is critical, as well as the development of new equipments capable of diminishing the production of greenhouse gases. Therefore, a new combustion bank was designed to be capable of allowing experiments on topics such as acoustic instabilities control, steam injection for emissions reduction, combustion with ash particles, swirl burner analyses and alternative fuels for power generation. Preliminary experiments and simulations were performed to characterize a new swirl combustor capable of reducing flashback via diffusive injection, nozzle constraints and high axial-tangential swirl, showing that the bank is capable of such studies. The use of acoustic signals to control the combustion was also tested, with results that showed that the use of the Minimal Squares Method is the most promising in the development of algorithms for thermoacoustic control.
