Abstract

Gives the testing of gas turbines supplied with gaseous or liquid fuels (or solid fuels converted to liquid or gas prior to entrance to the gas turbine).

Scope

This Code provides for the testing of gas turbines supplied with gaseous or liquid fuels (or solid fuelsconverted to liquid or gas prior to entrance to the gasturbine). Tests of gas turbines with emission controland/or power augmentation devices, such as injectionfluids and inlet-conditioning, are included. It may beapplied to gas turbines in combined cycle plants or with other heat recovery systems. This Code provides for comparative (back-to-back) tests designed to verify performance differentials of the gas turbine, primarily for testing before and after modifications, uprates, or overhauls. Improvements to achieve additional performance may include application ofadvanced gas path components, modification of combustion system, control scheme changes, increased mass flow, and changes to the inlet and exhaust systems of the gas turbine. The Code does not apply to the following: (a) gas turbines where useful output is other than power to drive a generator or other load device. (b) environmental compliance testing for gas turbines for stack emissions and sound levels. Procedures developed by regulatory agencies, ANSI, other ASME PTC Committees, or other equivalent standard, are available to govern the conduct of such testing. (c) overall plant power and thermal efficiency of gas turbine combined cycle and cogeneration facilities. Refer to ASME PTC 46 or equivalent standard. (d) absolute or comparative performance of specific components of the gas turbine. (e) performance of auxiliary systems of the gas turbine power plant, such as inlet cooling devices, fuel gas booster compressors, etc. (f) operational demonstration tests and reliability testing. (g) itemized performance changes that are the result of multiple actions, such as modifications, repairs, or cleanings (i.e., compressor, inlet air filtration systems, etc.).
