DAY 5

Special Session
Course participants will be taken through the computations of gas turbine and centrifugal performance tests on software supplied and the proper correction factors applicable.  It is suggested that attendees bring their lap top computers to class this day, so sample computations can be carried out in conjunction with the instructor. Performance computations will be as per various ASME codes PTC 19.1, and 22. 

Detailed Performance Testing Computations for Centrifugal Compressor and Gas Turbines

• Study of techniques for computing performance of the advanced gas turbines in design and off design operation.  NOTE: Most new advanced gas turbines operate at very high turbine firing temperatures.  Thus variation in this firing temperature significantly affects the performance and life of the components in the hot section of the turbine.  The compressor pressure ratio is high which leads to a very narrow operation margin, thus making the turbine very susceptible to compressor fouling.  The pressure drop through the air filter and dirty compressors also results in major deterioration of the performance of the turbine, thus emphasis will be placed on this computation.
• Centrifugal Compressor computations will be carried out as per ASME PTC 10.  The code deals with both field test as well as closed loop tests at the factory. 
• Examination of the three classification of the test will be examined and the computations compared.  Surge points and surge computations will be examined.
