👉 The CSTI, or Continuous Stability Index, is a metric used in combustion engineering to predict the stability of lean premixed combustion systems. It quantifies the ratio of the actual pressure at which combustion can occur stably to the pressure at which combustion would theoretically be stable under the same conditions. A higher CSTI value indicates better stability, meaning that the mixture can sustain combustion without excessive pressure drop or flame extinction. This index is crucial for designing and optimizing engines, gas turbines, and other combustion systems where lean fuel mixtures are used to improve efficiency and reduce emissions.
