How to Calculate Gas Turbine Inlet Temperature?

Click For Summary
SUMMARY

The discussion centers on calculating the turbine inlet temperature (TIT) for gas turbines using specific parameters such as fuel flow, compressor discharge temperatures, and the lower heating value (LHV) of fuel. Participants recommend utilizing NASA's Chemical Equilibrium with Applications (CEA) code, which is freely available and provides accurate estimations for TIT. Additionally, a technical document from GE Power offers valuable data on firing temperatures, serving as a reference for target values.

PREREQUISITES
  • Understanding of gas turbine operation principles
  • Familiarity with fuel flow measurement techniques
  • Knowledge of compressor discharge temperature metrics
  • Basic grasp of lower heating value (LHV) calculations
NEXT STEPS
  • Download and explore NASA's Chemical Equilibrium with Applications (CEA) code
  • Review the GE Power technical document on firing temperatures
  • Study the impact of fuel flow variations on turbine performance
  • Investigate advanced thermodynamic calculations for gas turbines
USEFUL FOR

Engineers, thermodynamic analysts, and professionals involved in gas turbine design and optimization will benefit from this discussion.

Does anyone have a spreadsheet with formulas or a set of formulas that one can use to determine the turbine inlet temperature of a gas turbine knowing measured parameters like fuel flow, compressor discharge tempuratures, LHV of fuel.
 
Physics news on Phys.org
Your best bet is to do a Google search for NASA's code CEA. It's free and will get you pretty close.
 
There is some data in this document on firing temps. At least these are target values.
