GAS TURBINE FIRING TEMPERATURE OPTIMIZATION BASED ON SULFUR CONTENT OF FUEL SUPPLY

摘要

PROBLEM TO BE SOLVED: To provide gas turbine firing temperature optimization based on a measured sulfur content of a fuel supply of a gas turbine system.SOLUTION: A system includes a diagnostic system 204 configured to determine a maximum firing temperature for a combustor 104 of a gas turbine system 100. The diagnostic system may determine the maximum firing temperature on the basis of a predetermined sulfur content-to-maximum firing temperature correlation and an actual sulfur content of a fuel supplied to the combustor. The diagnostic system may also be configured to provide an indicator for a change in an actual firing temperature in the combustor of the gas turbine system. The diagnostic system may provide the indicator in response to the determined maximum firing temperature differing from the actual firing temperature of the combustor of the gas turbine system.
