PTC 22 - Gas Turbines

PTC 22 establishes directions and rules for the conduct and results reporting of thermal performance tests for open cycle gas turbine power plants and gas turbine engines. This performance test code provides explicit instruction on determining corrected power, heat rate (efficiency), exhaust flow, exhaust energy, and exhaust temperature. Guidance is also provided for designing testing requirements and programs to satisfy different goals such as absolute performance and comparative performance. The most significant changes in this edition are to Sections 1, 4, 5, and 7, Mandatory Appendix I and Nonmandatory Appendix C. Most notably, the methodology for electrical generator measurement in this edition has been revised to align with the methodology used in ASME PTC 19.6-2018.

PTC 22 is used in power plants worldwide and is recognized internationally. This performance test code was developed by a committee with balanced membership from manufacturers, power plant owners and operators, design engineers, and general interest groups.

Intended for: end-users, test engineers, operators of power plants, plant engineers, A/E’s, gas turbine manufacturers, third-party testing agencies, and anyone else who specifies gas turbine testing.
