Patent 7246493 was granted and assigned to Siemens Aktiengesellschaft on July, 2007 by the United States Patent and Trademark Office.
The invention relates to a gas turbine comprising a combustor that extends into a combustion chamber. The port of the combustor is surrounded in a ring-shaped manner by a Helmholtz resonator, whereby combustion oscillations are effectively suppressed due to close contact with the flame while irregularities in temperature are prevented.
