ASME PTC 51-2011 (R2016)

This Code provides procedures for in situ testing of inlet air-conditioning systems (cooling/heating) as they apply to gas turbines in simple, cogeneration, and combined- cycle applications.

The intent of this Code is to provide results with the lowest reasonably achievable uncertainty consistent with the best engineering knowledge and practice in the industry, such that appropriate instrumentation and measurement techniques and procedures be used to determine the following performance variables, as applicable:

• performance factor
• carryover
• auxiliary consumption (power/thermal)
• temperature change
• water discharge
• water consumption
• distribution/stratification
• pressure drop

This Code also provides procedures for the calculation of the results, and for the correction of the results to reference conditions, as a measure of gas turbine inlet air-conditioning systems performance.
