Poster session presented at IUPUI Research Day 2012, Indianapolis, Indiana.https://hdl.handle.net/1805/7655poster abstractIn order to conform to pollutant-related legislations and minimize NOx emissions, modern household boilers and central heating systems are mov-ing towards premixed combustors. These combustors have been very suc-cessful with regards to emissions along with thermal efficiency. However, there implementation has been associated with acoustical instability prob-lems that are best solved through precise design optimization rather than trial and error experimentation. This poster introduces an experimental setup which is designed to inves-tigate and study, acoustic instability at the flame level. The methodology is an experimental determination of the Flame Transfer Function and compari-son of the experimental data with a theoretical model of the flame-burner. A procedure is designed to diagnose the origins of the combustion instabilities by measurement of the Flame Transfer Function experimentally. The exper-imental setup provides an improved assessment of the acoustic instability problem for industrial applications.en-USFLAME TRANSFER FUNCTIONNOx emissionscombustorsacoustic instabilityPoster
