Systems comprised of hot and cold components containing gaseous fluids may be subject to thermoacoustic oscillations if the temperature gradient between the two components exceeds a critical value. An evaluation of the Sondhauss-type and the Rijke-type thermoacoustic oscillations in combined turbine/heat exchanger/duct systems and furnace/burner systems will be presented. Parameters which will reduce or eliminate the likelihood of thermoacoustic oscillations in such systems are identified and discussed in this paper.
