Abstract

Although investigated for many years, real-time monitoring of combustion dynamics is still an important issue in modern gas turbine operation. In this article, attention is focused on two quantities, radiant energy and pressure, sampled in an industrial combustion system. Based on such quantities, and with the aim of selecting the best operational index to detect instability precursors, different strategies are here defined and compared. Upon the obtained results, the adopted monitoring and signal analysis strategy reveals promising as an online practical method to detect combustion instabilities.

工业燃烧系统动态状态的在线表征

尽管经过多年的研究，燃烧动力学的实时监测仍然是现代燃气轮机运行中的一个重要问题。在本文中，关注的重点是两个量，辐射能量和压力，在一个工业燃烧系统的采样。基于这些数量，并以选择最佳操作指标来检测不稳定前兆为目标，定义并比较了不同的策略。结果表明，所采用的监测和信号分析策略有望成为一种在线检测燃烧不稳定性的实用方法。
