The following information is based on that document and is included here for emphasis and for the convenience of the user of the Code. It is expected that the Cod

22、e user is fully cognizant of Sections 1 and 3 of ASME PTC 1 and has read them prior to applying this Code.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. They were

23、 developed by balanced committees representing all concerned interests and specify procedures, instrumentation, equipment-operating requirements, calculation methods, and uncertainty analysis.When tests are run in accordance with a Code, the test results themselves, without adjustment for uncertaint

24、y, yield the best available indication of the actual performance of the tested equipment. ASME Performance Test Codes do not specify means to compare those results to contractual guarantees. Therefore, it is recommended that the parties to a commercial test agree before starting the test and prefera

25、bly before signing the contract on the method to be used for comparing the test results to the contractual guarantees. It is beyond the scope of any Code to determine or interpret how such comparisons shall be made.viFOREWORDASME Performance Test Codes (PTCs) have been developed and have long existe

26、d for determining the performance of most major components used in electric power production facilities. A PTC has heretofore not existed to determine the overall performance of an integrated gasification combined cycle (IGCC) power generation plant. The ability to fire a wide range of fuels has bee

27、n a key advantage of gas turbines over competing technologies. Until recently, the tradi-tional fuels for gas turbines have been natural gas and liquid fuels. Today, environmental concerns and economic con-siderations are causing power generation suppliers to develop gasification systems that can us

28、e solid and liquid fuels (e.g., coal, biomass, waste, and heavy oils). Preparation of an alternative fuel suitable for a gas turbine includes removal of ash, contaminants, erodents, and corrodents. In response to these needs, the ASME Board on Performance Test Codes approved the formation of the PTC

29、 47 Committee in 1993 with the charter of developing a code for determining overall power plant performance of gasification power generation plants. The organizational meeting of this Committee was held in November 1993. The resulting Committee included experienced and qualified users, manufacturers

30、, and gen-eral interest personnel.The Committee has striven to develop an objective code that addresses the multiple needs for explicit testing methods and procedures, while attempting to provide maximum flexibility in recognition of the wide range of plant designs.This Code was approved by the PTC

31、47 Committee and the PTC Standards Committee on February 3, 2015. It was then approved as an American National Standard by the America National Standards Institute (ANSI) Board of Standards Review on May 22, 2015.viiASME PTC COMMITTEEPerformance Test Codes(The following is the roster of the Committe

37、elated Codes:(a) ASME PTC 47, Integrated Gasification Combined Cycle Power Generation Plants, for testing the overall plant performance on an IGCC plant.(b) ASME PTC 47.1, Cryogenic Air Separation Unit, for testing the performance of the air separation unit (ASU). If the physical IGCC plant includes

38、 an ASU, the inclusion of the ASU within the overall test envelope is recommended but not required. (c) ASME PTC 47.2, Gasification System, for testing the thermal performance of the combined gasifier and fuel gas cleaning equipment.(d) ASME PTC 47.3, Fuel Gas Cleaning, for testing the contaminant c

39、ontent of gas delivered to the power block.(e) ASME PTC 47.4, Power Block of an Integrated Gasification Combined Cycle Power Plant, for testing the thermal performance of the gas turbine combined cycle power block.NOTE: ASME PTC 47.1, ASME PTC 47.2, and ASME PTC 47.3 are in the course of preparation

40、.It is recommended that overall plant and subsystems be tested separately, not simultaneously, to accommodate any boundary constraints and valve isolations and lineups that may be needed for subsystem testing. In highly integrated IGCC plants, the entire plant may need to be operating during a subsy

41、stem test, even though the only performance parameters being measured are those of the subsystem.Test results can be used as defined by a contract to determine the fulfillment of contract guarantees. Test results can also be used by a plant owner to compare plant performance to a design number, or t

42、o trend plant performance changes in time. However, the results of a test conducted in accordance with this Code will not provide a basis for comparing the thermoeconomic effectiveness of different plant designs.xINTENTIONALLY LEFT BLANKASME PTC 47.4-2015POWER BLOCK OF AN INTEGRATED GASIFICATION COM

43、BINED CYCLE POWER PLANTSection 1Object and Scope11-1 OBJECTThe object of this Code is to provide uniform test methods and procedures for the determination of the thermal performance and electrical output of an inte-grated gasification combined cycle (IGCC) power block.(a) This Code provides explicit

44、 procedures for the determination of the following performance results:(1) corrected net power(2) corrected net heat rate(3) corrected heat input(b) Tests may be designed to satisfy different goals, including(1) specified disposition(2) specified net corrected power(3) specified net power1-2 SCOPETh

45、is Code applies to combined cycle power plants (power blocks) that operate in conjunction with a gasi-fication plant, an IGCC power plant, or an IGCC cogen-eration plant. This Code does not apply to power blocks other than those associated with IGCC plants.This Code is applicable to the combined cyc

46、le power block of IGCC power plants, whereas ASME PTC 46 is applicable to conventional combined cycles. The ther-mal streams and corrections in ASME PTC 46 for con-ventional combined cycles are normally limited to gas or liquid hydrocarbon fuel input and steam or water input. In ASME PTC 47.4, test

47、measurements and associ-ated corrections are needed to address multiple thermal streams such as heated hydrocarbon syngas fuel input, water and steam inputs from gasification process units, nitrogen input from the air separation plant, and air extraction to the air separation plant. Emissions tests,

48、 operational demonstration tests, and reliability tests are outside the scope of this Code.1-3 UNCERTAINTYThe explicit measurement methods and procedures to be used for the power block of an IGCC have been developed to provide guidelines for test procedures that yield results of the highest level of

49、 accuracy based on current engineering knowledge, taking into account test costs and the value of information obtained from testing. The calculation of test uncertainty shall be performed in accordance with ASME PTC 19.1 and as outlined in this Code.Because of the diverse range of integration of the power block with the gasification block and the air sepa-ration unit block, the test results will have different lev-els of uncertainty.A pretest uncertainty analysis shall be performed to establish the expected level of uncertainties for the test.
