Voodook ASME does not approve, rate, or endorse any item, construction, proprietary device, or activity. Before testing, but after the on-site wiring connections are made, there shall be sufficient comparisons of all similar temperature sensors to ensure their relative accuracy.

Hays, Honorary Member, Retired T. Aske to 9 in. ASME Performance Test Codes provide test procedures that yield results of the highest level of accuracy consistent with the best engineering knowledge and practice currently available.

Methods necessary to quantify the effects as,e test results shall be determined by mutual agreement. Through prior discussion or prior agreement, one person or a team consisting of one person from each test party shall be responsible for the test, operational coordination, cal- culations, and test results. This Code doesnot address test tolerance, margin, or allowance sincethese are commercial terms. The average value for such parameters is subject to spatial bias.

Any departure from Coderequirements could introduce additional uncertaintybeyond that considered acceptable to meet the objectivesof the Code. A large national Committee was convened the following year that was comprised of experts from manufacturing, utility-owners, test agency, academia, and consultants in the field. Deviations from the methods stated in this Code are acceptable only if it can be demonstrated to the test parties that the deviations provide equal or lower uncer- tainty in the calculated test result.

As internal access is typically impractical after installa-tion of the ACC, an internal test connection should bespecified during the ACC design. Exhaust Enthalpy should correspond with each case. To the extent possible, ancillary system drains flowinginto the condensate tank or other parts of the ACC dur-ing the test shall be closed. Calibrations should encompass theexpected measurement range and be comprised of atleast two points more than amse order of any calibrationcurve Prior to starting the test, the plantmust be operated for a sufficient period of time at testload to demonstrate and verify stability in accordancewith para.

The proposed code or standard was made available for public review and comment that provides an opportunity for additional public input from industry, academia, regulatory agencies, and the public-at-large.

It istypically supplied and tested as part of the ACC. Friedman, Siemens Power Generation, Inc. The curves of Fig. The designconditions including steam mass flow rate, steam tur-bine backpressure, steam quality, fan motor input power,atmospheric pressure, and inlet air dry bulb temperatureshall be printed on the curves. They were developed by balanced committees representing all concerned interests and specify procedures, instrumentation, equipment-operating requirements, calculation methods, and uncer- tainty analysis.

Internal test points, such as basket tips and ther-mowells, should be located to avoid interference withinternal steam duct structure, bracing, turning vanes,etc. When CFD studies are con- ducted before the plant operates but after the ACC design arrangement is established, the simulation can determine the minimal number of temperature sensors that can be utilized in a performance-monitoring pro- gram.

For additional details,see Nonmandatory Appendix K. The instrumental uncertainty of each of the test parameters is summarized in Table C Such proposals should be as specific as possible, citing the paragraph number sthe proposed wording, and a detailed descrip- tion of the reasons for the proposal, including any pertinent documentation.

Our representatives are ready to assist you in the following areas: Anyspecified or contract operating conditions, or any speci-fied performance that are pertinent to the objective ofthe test shall be ascertained. Repeat Steps tpc and 9 for inlet air dry-bulbtemperature. The friction across the tube bank and heat transfer from steam to air is also included. Stability may need to be established following any adjustment.

For a commercial aame, this phi-losophy is in the best interest of all parties to the test. All test parties shall have a clear understanding of the test object, the proposed procedures, and axme results to be obtained. Recognizing, however, the importance of minimal turbine exhaust pressure on plant generation, the Committee also featured aame Appendices of the Code that address both methods of Performance Monitoring and Routine Performance Testing.

Spreadsheet software is a useful calculationtool for this program. The application of uncertainties to adjust test resultsis not part of this Code; the test results themselves pro-vide the best indication of actual performance.

The method and results of this correction shall be mutually agreed between the parties and taken into account in the fan motor input power measurement. The duration of 2 days ensures that a sufficient variation of uncontrolled conditions, such as wind speed and direction, within the limits of the Code are encountered.

ASME PTC R — Air-Cooled Steam Condensers To gain reliable ambient wind velocity, the wind veloc- ity shall be measured at least 5 m above grade at a location within the plant without interference from other equipment, buildings, structures, and topography. Adjustments to avoid corrections or to min-imize the magnitude of performance corrections are per-missible e.

The condensatetemperature correction curves should consist of the con-densate temperature as function of the ACC pressureand total steam flow rate expressed in percentage ofdesign steam aeme rate. These points shall be symmetrically distributed about the perimeter of the steam turbine exhaust duct as near the flange of the steam turbine exhaust or pressure guarantee location as possible. Backfitting an existing system for the required measurements can be very expensive and time-consuming at best, and virtu- ally impossible at worst.

The ACC performance curves shall be based on constant fan pitch and motor speed constant volumetric air flow rate. Related Posts

From a heat transfer surface standpoint, this Code covers all tube bundle orientations, including: vertical, horizontal, and slanted conduit heat exchangers. Both bare surfaces and finned surfaces are included as conduit type heat exchanger components. While conventional round tubes with circular fins are assumed in this Code, the procedures can be modified by mutual agreement to apply to other surface configurations. While the cooling fluid is restricted to atmospheric air, the tube-side fluid can be any chemical element, compound or mixture, in single-phase flow, liquid or gas, or in two-phase flow. This Code is written under the assumption that the Air Cooled Heat Exchanger ACHE may be tested as having a discrete process stream or that only one process fluid stream is being investigated. In other cases, modifications must be made to the procedures presented.

It provides rules for conducting acceptance tests, along with guidelines for monitoring thermal performance and conducting routine tests. The test can be used to determine compliance with contractual obligations; and the Performance Test Code can be incorporated into contractual agreements. The test can be used to determine compliance with contractual obligations and the Code can be incorporated into commercial agreements. A test shall be considered an ASME Performance Code Test only if the test procedures comply with those stipulated in this Performance Test Code and the post-test uncertainty analysis results are in accordance with subsection The explicit measurement methods and procedures have been developed to provide a test of the highest level of accuracy consistent with practical limitations for acceptance testing.
