Eliminating thermoacoustic oscillations in heat exchanger and steam generator systems

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