ASME, Performance Test .ode on GasTurbines, ASME PT. 22 1997
The object of the code is to detail the test to determine the power output and thermal efficiency of the gas turbine when operating at the test condi-tions, and correcting these test results to standard or specified operating and control conditions. Procedures for conducting thetest, calculating theresults, and making the corrections are defined.
The code provides for the testing of gas turbines supplied with gaseous or liquid fuels (or solid fuels converted to liquid or gas prior to entrance to the gas turbine). Test of gas turbines with water or steam injection for emission control andjor power augmentation are included. The tests can be applied to gas turbines in combined-cycle power plants or with other heat recovery systems.
Meetings should be held with all parties concerned as to how the test will be conducted and an uncertainty analysis should be performed prior to the test. The overall test uncertainty will vary because of the differences in thescope ofsupply, fuel(s)used, and driven equipment characteristics. The code establishes a limit for the uncertainty of each measurement required; the overall uncertainty is then calculated in accordance with the procedures defined in the code and by ASME PTc 19.1.
Mechanical Parameters
Some of the best standards from a mechanical point of view have been written by the American Petroleum Institute (API) and the AmericanSociety of Mechanical Engineers, as part of their mechanical equipment standards. The ASME and the API mechanical equipment standards are an aid in specifying and selecting equipment for general petrochemical use. The intent of these specifications is to facilitate the development of high-quality equipment with a high degree of safety and standardization. The user.s problems and experience in the field are considered in writing thesespecifications. The taskforce, which writes the specifications, consists ofmembers from theuser, the contractor, and the manufacturers.Thus, the task-force team brings together both experience and know-how.
The petroleum industry is one of the largest users of gas turbines as prime movers for drives of mechanical equipment and also for power generationequipment. Thus the specifications written are well suited for thisindustry, and the tips of operation and maintenance apply for all industries. This section deals with some of the applicable API and ASME standards for the gas turbine and other various associated pieces.
It is not the intent here to detail the API or ASME standards, but to discuss some of the pertinent points of these standards and other available options. It is strongly recommended that the reader obtain from ASME and API all mechanical equipment standards.
API Std616, Gas Turbines for thePetroleum,.hemical, and Gas IndustryServices, 4thEdition, August 1998
This standard covers the minimum requirements for open, simple, and regenerative-cycle combustion gas turbine units for services of mechanicaldrive, generatordrive, or process gas generation. All auxiliary equipment required for starting and controlling gas turbineunits, and for turbine protection is either discussed directly in this standard or referred to in thisstandard through references to other publications. Specifically, gas turbine units that are capable of continuous service firing gas or liquid fuel or both are covered by this standard. In conjunction with the API specifications the following ASME codes also supply significant data in the proper selection of the gas turbine.
ASME Basic Gas Turbines B 1...2 Published: 1977 (Reaffirmed Year: 1997)
This standard presents and describes features that are desirable for the user to specify in order to select a gas turbine that will yield satisfactoryperformance, availability, and reliability. The standard is limited to a con-sideration of the basic gas turbine including the compressor, combustionsystem, and turbine.
