Zusammenfassung:A method of monitoring for combustion anomalies in a gas turbomachine includes sensing an exhaust gas temperature at each of a plurality of temperature sensors arranged in an exhaust system of the gas turbomachine, comparing the exhaust gas temperature at each of the plurality of temperature sensors with a mean exhaust gas temperature, determining whether the exhaust gas temperature at one or more of the plurality of temperature sensors deviates from the mean exhaust temperature by a predetermined threshold value, and identifying an instantaneous combustion anomaly at one or more of the temperature sensors sensing a temperature deviating from the mean exhaust temperature by more than the predetermined threshold value. 种监测燃气涡轮机中的燃烧异常的方法包括:感测布置在燃气涡轮机的排气系统中的多个温度传感器中的每个处的排出气体温度,将多个温度传感器中的每个处的排出气体温度与平均排出气体温度相比较,确定多个温度传感器中的个或更多个处的排出气体温度是否偏离平均排气温度达预定阈值,以及识别感测到偏离平均排气温度大于预定阈值的温度的温度传感器中的个或更多个处的瞬时燃烧异常。
