BS ISO 2314:2009

This standard BS ISO 2314:2009 Gas turbines. Acceptance tests is classified in these ICS categories:
  • 27.040 Gas and steam turbines. Steam engines

This International Standard applies to open-cycle gas-turbine power plants using combustion systems supplied with gaseous and/or liquid fuels as well as closed-cycle and semi-closed-cycle gas-turbine power plants. It can also be applied to gas turbines in combined cycle power plants or in connection with other heat-recovery systems.

In cases of gas turbines using free-piston gas generators or special heat sources (for example synthetic gas of chemical processes, blast furnace gas), this International Standard can be used as a basis but suitable modifications are necessary.

Acceptance tests of gas turbines with emission control and/or power augmentation devices that are based on fluid injection and/or inlet air treatment are also covered by this International Standard and it is necessary that they be considered in the test procedure, provided that such systems are included in the contractual scope of the supply subject to testing.

Comparative testing can be subject to many different scenarios, depending on the purpose of the conducted measures. This International Standard can also be applied to comparative tests designed to verify performance differentials of the gas turbine, primarily for testing before and after modifications, upgrades or overhaul, although no special reference is made to these topics.

This International Standard also includes procedures for the determination of the following performance parameters, corrected to the reference operating parameters:

  1. electrical or mechanical power output (gas power, if only gas is supplied);

  2. thermal efficiency or heat rate;

  3. turbine exhaust energy (optionally exhaust temperature and flow).

It is necessary that any other performance parameters defined in the contract between equipment supplier and purchaser be considered accordingly in the specific test procedure as well as in the supplier's standard manufacturing test procedure.

This International Standard describes measurement methods and corresponding instruments employed and their calibration arrangement and handling. It includes provisions for preparing and conducting a performance test, defines operating conditions of the gas turbine, boundary conditions and their limits as well as standard conditions (3.9) that should be used as a reference if no other conditions are agreed at the time of purchase. Furthermore, it contains provisions for the measurement data recording and handling, methods for the calculation and correction of the test results as well as the development of the uncertainty thereof.

Test tolerance is not addressed in this International Standard, because it is considered a commercial term not based on statistical analysis of measurement results. It is necessary that the methodology on how to apply tolerances for the demonstration of compliance with the guaranteed values be defined in the contract.

For the optional test to determine exhaust energy and/or flow, these values are determined from an energy balance around the gas turbine. Uncertainty values can be minimized by achieving the limits defined in this International Standard for the key parameters in the energy balance.

This International Standard does not apply to the following:

  1. emission testing;

  2. noise testing;

  3. vibration testing;

  4. performance of specific components of the gas turbine;

  5. performance of power augmentation devices and auxiliary systems, such as air inlet cooling devices, fuel gas compressors, etc.;

  6. conduct test work aiming at development and research;

  7. adequacy of essential protective devices;

  8. performance of the governing system and protective systems;

  9. operating characteristics (starting characteristics, reliability testing, etc.).
