PTC6-2004
Steam Turbines
$225.00

This Code provides procedures for the accurate testing of steam turbines. It is recommended for use in conducting acceptance test of steam turbines and any other situation in which performance levels must be determined with minimum uncertainty. It may be used for testing of steam turbines operating either with a significant amount of superheat in the initial steam (typically fossil-fueled units) or predominantly within the moisture region (typically nuclear- fueled units). This Code contains rules and procedures for the conduct and reporting of steam turbine testing, including mandatory requirements for pretest arrangements, instruments to be employed, their application and methods of measurement, testing techniques, and methods of calculation of test results. The performance parameters which may be determined from a Code test include: (a) heat rate, (b) generator output, (c) steam flow, (d) steam rate, (e) feedwater flow. It also contains procedures and techniques required to determine enthalpy values within the moisture region and modifications necessary to permit testing within the restrictions of radiological safety requirements in nuclear plants.

PTC6.2-2004
Steam Turbines in Combined Cycles
$125.00

This Code may be used for testing steam turbines in combined cycles with or without supplementary firing and in cogeneration applications. Within these categories of combined and cogeneration cycles, this Code is applicable to condensing and noncondensing steam turbines, to reheat and nonreheat steam turbines, and to induction/ extraction steam turbines. The variety of cycles presents challenges in writing a code that addresses all issues encountered for all cycle configurations. ASME PTC 6 is the appropriate code for testing steam turbines in nuclear and fossil- fired regenerative feedwater heater cycles. This Code is applicable only to turbines in cycles in which steam is the working fluid. This Code provides procedures for testing and calculating turbine-generator output performance corrected to reference conditions as a measure of overall turbine performance. This Code contains rules and procedures for the conduct and reporting of steam turbine testing, including requirements for pretest arrangements, testing techniques, instrumentation, methods of measurement, and methods for calculating test results and uncertainty.

PTC6A-2000
Appendix A to PTC 6 The Test Code for Steam Turbines
$130.00

This appendix has been prepared to facilitate the calculation and correction of turbine test results by furnishing numerical examples of the procedures outlined in PTC 6, the Performance Test Code on Steam Turbines. The feedwater heating cycles and gland leak-off systems have been simplified by avoiding unnecessarily long or repetitive calculations while still demonstrating the basic principles involved. The general guidelines for making these calculations and comparisons to specified performance are given.

PTC6-REPORT-1985(R1997)
Guidance for Evaluation of Measurement Uncertainty in Performance Tests of Steam Turbines
$65.00

Reaffirmed Date: 1997

The object of this Report is to provide guidance for the parties to the test to establish the degree of uncertainty of the test results when there are deviations from requirements of PTC 6. Numerical values have been assigned to the uncertainty of instruments of various qualities. These values cover 95% uncertainty intervals.

PTC6S-1988(R2003)
Procedures for Routine Performance Test of Steam Turbines
$95.00

Reaffirmed Date: 2003

The test procedures of this Report are intended for periodic steam turbine tests. It may also be used for the analysis and supervision of relative performance throughout the life of the turbine. It does not supplant the Code (PTC 6) as the basic procedure for turbine acceptance tests and for the accurate testing of steam turbines to obtain performance level with minimum uncertainty. This Report provides general recommendations for instrumentation and test planning. These recommendations are based on current industry practice for the periodic determination of turbine cycle performance. This Report discusses interpretation of test results and shows typical plots of test data for analysis of turbine performance. It also presents test procedures for selected types of turbine cycles. Each of these procedures contains specific recommendations for instrumentation and method for testing a selected turbine type. Although all possible turbine types are not covered, some typical examples are presented. Combinations of the types presented may be used to cover other arrangements. For each recommended test procedure, the expected value of repeatability is estimated on the basis of current industry experience. This value of repeatability must be used to judge the significance of the indicated level of performance as compared to the chronological trend of past performances.
