GAS TURBINE TEMPERATURE SENSOR VALIDATION APPARATUS AND METHOD

摘要

An arrangement for determining the validity of temperature sensor readings of a gas turbine hot gas stream which includes means for comparing each reading to predetermined bounds. The temperature sensors are arranged so that a temperature streak caused by a combustion system malfunction would affect more than one sensor. In some cases, when a suspect reading is identified, the readings from adjacent sensors are examined before the suspect reading is rejected.
