ASME PTC 22

Abstract

This Code provides for 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). Tests of gas turbines with emission control and/or power augmentation devices, such as injection fluids and inlet air treatment, are included. It may be applied to gas turbines in combined cycle plants or with other heat recovery systems.<br>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.<br>The Code does not apply to the following:<br><em>(a)</em> gas turbines where useful output is other than power to drive a generator or other load device<br><em>(b)</em> environmental compliance testing for gas turbines for stack emissions and sound levels. Procedures developed by regulatory agencies, ANSI, or other PTC Committees are available to govern the conduct of such testing.<br><em>(c)</em> overall plant power output and thermal efficiency of gas turbine combined cycle and cogeneration facilities. Refer to PTC 46.<br><em>(d)</em> performance of specific components of the gas turbine<br><em>(e)</em> performance of auxiliary systems of the gas turbine power plant, such as inlet cooling devices, fuel gas booster compressors, etc.
