    Abstract: The present disclosure is directed to a fuel manifold assembly for a gas turbine engine. The fuel manifold assembly defines a walled conduit through which a fuel flows in a fuel passage. The walled conduit defines a first end and a second end opposite of the first end along a length of the walled conduit. The fuel manifold assembly includes an exit manifold to which a fuel nozzle attaches. The fuel manifold assembly includes a damper assembly coupled to the walled conduit of the fuel manifold assembly. The damper assembly includes a walled tube extended from the walled conduit. The damper assembly further includes a walled enclosure defining a damper cavity therein. The damper cavity is in fluid communication with a damper passage defined within the walled tube, and the damper passage is in fluid communication with the fuel passage.

    Abstract: The present disclosure provides a method for controlling combustor cans of a gas turbine. Detectors disposed on combustor cans are operable to detect combustion vibration values of the combustor cans. The combustion vibration value is compared to a reference value. Combustor cans having a combustion vibration value greater than a reference value are assigned to a first group, and combustor cans having a combustion vibration value not greater than the reference value are assigned to a second group. The output of each combustor can in the first group is regulated to lower the combustion vibration value, thereby improving the stability of the gas turbine.

    Abstract: A burner for a gas turbine, has an air passage supplied with compressed air and a fuel passage supplied with fuel gas, each passage has a main outlet opening leading into the combustion chamber of the gas turbine, the air and fuel passages connected fluidically together via a connection duct arranged upstream of the main outlet openings. The burner is configured such that, when air passage is supplied with compressed air and fuel passage is supplied with fuel gas, a portion of the fuel gas flowing in the fuel passage flows via at least one connection duct into the air passage and, for combustion thereof, is introduced through the main outlet opening of the air passage into the interior of the combustion chamber and a remaining portion of the fuel gas is introduced through the main outlet opening of the fuel passage into the interior of the combustion chamber.
