Description / Abstract:

Sections 3 through 5 of this Report present general recommendations for instrumentation and test planning. These recommendations are based on current industry practice for the periodic determination of turbine-cycle performance. Section 6 discusses interpretation of test results and shows typical plots of test data for analysis of turbine performance. Sections 7 through 12 present test procedures for selected types of turbine cycles. Each of these procedures contains specific recommendations for instrumentation and method for testing's elected 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 s compared to the chronological trend of past performance. (See para. 3.8.3 for discussion of repeatability.)

PURPOSE OF REPORT

This Report provides turbine-test procedures for the analysis and supervision of relative performance throughout the life of the turbine. These procedures will determine trends of operating efficiency, detect trouble, and furnish test data to evaluate efficiency changes in the turbine cycle. These procedures are designed to minimize test instrumentation and personnel. However, precision instrumentation at critical test locations is recommended for reliable results. A high degree of repeatability, rather than the acceptance test level of performance, is sought
