Abstract
A dampening device for suppressing vibrations of a tube assembly in a catalytic combustor which includes, a plurality of closely oriented, parallel tubes with each tube having at least one expanded region and at least one narrow region. The expanded regions being structured to contact at least one adjacent tube, thus providing support and minimizing degradation of the joint connecting the tubes to the tube sheet, and degradation of the tubes themselves. Such degradation can result from vibration due to flow of cooling air inside of the tubes, flow of the fuel/air mixture passing over the tubes transverse and longitudinal to the tube bundle, and/or other system/engine vibrations.
