Gas Turbine Inlet Air-Conditioning Equipment
 N PTC 51

Annotation

This Code may be used for in situ testing of inlet airconditioning systems (cooling/heating) as they apply to gas turbines in simple, cogeneration, and combinedcycle applications. Cooling systems covered by this Code include evaporative systems (foggers and media-based evaporative coolers) and mechanical/thermal refrigeration systems. Heating systems covered by this Code include compressor-bleed type systems and heating-coil systems.

This Code is limited to gas turbine inlet air-conditioning systems and does not apply to the following:

– building heating, cooling, or refrigeration systems

– gas turbine compressor intercoolers

– wet compression, overspray, deluge, overfogging, and similar technologies

– other power plant applications such as air-cooled electrical generators

– gas turbine performance

In addition, this Code does not apply to the testing of individual atomizing nozzles. However, the Committee recognizes that carryover is a critical characteristic of fogging systems. As such, there may be situations that require the quantification of water droplet size. To address this need, the Code further provides the procedures for determining water droplet size associated with laboratory bench testing of atomizing nozzles; please see Nonmandatory Appendix A.

This Code contains rules and procedures for conducting and reporting tests of gas turbine inlet air-conditioning systems, including requirements for pretest arrangements, testing techniques, instrumentation, methods of measurement, and methods for calculating test results and uncertainty.
