    摘要: Combustion chamber dynamics in a turbine system are detected by obtaining (1) pilot flow measurement values from at least one fuel pilot flow sensor and pressure band measurement values from at least one pressure sensor in at least two distinct pressure bands, checking (2) the pilot flow measurement values against a first criterion and the pressure band measurement values against a second criterion, and detecting (3) combustion chamber dynamics and outputting (4) a warning or an alert if both the pilot flow measurement values and the pressure band measurement values match their respective criteria. The method may rely on measurement data that are already provided by any turbine system (for use in corresponding control systems) and can thus be carried out without the need for any additional measurement hardware or other modifications of the turbine system itself. It provides a simple heuristic method which can automatically recognize and report the HPCCD failures. It is simple in formulation and can easily be understood by any engineer. It is also simple in computation, therefore it can be realized in any modern monitoring system. It enhances the current methods realized in the control systems and can report both early HPCCD warnings as well as critical HPCCD failures. Furthermore, it can be done uniformly for a whole turbine fleet.

    摘要: A combustor can assembly (100) includes a plurality of combustor cans (110) spaced circumferentially about a gas turbine engine. Each combustor can (110) is coupled in flow communication with at least one fuel manifold (130) via a respective can fuel line (140). The combustor can assembly (100) also includes a first interconnecting fuel line (452) that includes a first end (453) and a second end (454). The first end is coupled in flow communication with the can fuel line (142) of a first combustor can (122), and the second end (454) is coupled in flow communication with the can fuel line (146) of a third combustor can (126) that is not circumferentially adjacent to the first combustor can (122) . The combustor can assembly (100) further includes a first control device (450) operatively coupled to the can fuel line (142) of the first combustor can (122). The first control device (450) is operable to change a dynamic operational characteristic of the first (122) and third (126) combustor cans independently of other combustor cans (110).
