Abstract: The invention refers to a sequential combustor arrangement comprising a first burner, a first combustion chamber, a mixer for admixing a dilution gas via a dilution gas inlet to the hot gases leaving the first combustion chamber during operation, a second burner, and a second combustion chamber arranged sequentially in a fluid flow connection. The sequential combustor arrangement further includes four cooling zones with a cooling channel. During operation a cooling gas flows through the cooling channels. The disclosure further refers to a method for operating a gas turbine with such a sequential combustor arrangement.

Abstract: A tuning process is provided for dynamically tuning a gas-turbine (GT) engine to correct for flashback events without directly measuring occurrences of the flashback events at the GT engine. Initially, readings are taken that measure low-frequency dynamics at the GT engine. A determination of whether flashback criteria are met by an instantaneous signal that quantifies a detected spike within the measured low-frequency dynamics is carried out, where the flashback criteria include the following: identifying the spike overcomes a multiple of an average of the low-frequency dynamics measured over a predefined period of time; and identifying the spike overcomes a preestablished minimum amplitude. Upon the spike meeting the flashback criteria, a count is added to a running record of spikes, which is compared to an alarm limit. If the alarm limit is triggered, action(s) are invoked to address the flashback events, such as adjusting fuel-flow splits of the GT engine.
Abstract translation: 提供了一种调节过程，用于动态调整燃气轮机（GT）发动机，以校正闪回事件，而不直接测量GT发动机的闪回事件的发生。 最初，采用测量GT发动机低频动力学的读数。 执行闪光标准是否通过在所测量的低频动态中量化检测到的尖峰的瞬时信号来满足闪回标准，其中闪回标准包括以下：识别尖峰克服了低频的平均值的倍数 动态测量在预定义的时间段内; 并且识别尖峰克服了预先建立的最小幅度。 当峰值满足闪回标准时，会将一个计数添加到运行中的尖峰记录，与报警限制进行比较。 如果触发报警限制，则调用动作来解决闪回事件，例如调整GT引擎的燃油流量分配。
