What is the difference between flame temperature and firing temperature in Gas turbines?

 

Firing temperature is defined as the temperature of hot gases which enters 1st stage turbine buckets. This is the temperature at which work is extracted in gas turbine.

Flame temperature, is the temperature in side the combustion liner, the highest temperature reached inside the Gas turbine hot gas path.

 

This topic has been covered many times before on control.com.

Cleverly hidden at the far right of the Menu bar at the top of every control.com page is a 'Search' field. Type "+firing +temperature" (without the quotes) into the field and click on the question mark (or, just press ENTER on the keyboard), and you will find many references to firing temperature.

 

A slight clarification: On machines with air-cooled nozzles, firing temperature is defined as the temperature of the hot gases exiting the first-stage turbine nozzles. (We're only talking a few degrees F difference, but it is a difference.)

 

Yes, that's right.
