  • Gas turbine overtemperature protection
    Patent number: 4910956
    Abstract: Turbine gas temperature, which escalates during a compressor stall, is monitored 46, and compared to a set point temperature 52. If the set point temperature is exceeded, valve 36 is pulsed discharging fuel from line 24 and reducing flow to the combustor. Open and closed intervals are selected to reduce flow, but to avoid flameout. An additional second valve 42 operates in a similar mode in response to an even higher gas temperature.Engine operation continues in this temperature protection mode until the stall is corrected by whatever means.
