24、onvenience of the user of the Code. It is expected that the Code user isfully cognizant of Sections 1 and 3 of ASME PTC 1 and has read them prior to applying thisCode.ASME Performance Test Codes provide test procedures that yield results of the highest levelof accuracy consistent with the best engin
25、eering knowledge and practice currently available.They were developed by balanced committees representing all concerned interests and specifyprocedures,instrumentation,equipment-operatingrequirements,calculationmethods,anduncer-tainty analysis.When tests are run in accordance with a Code, the test r
26、esults themselves, without adjustmentfor uncertainty, yield the best available indication of the actual performance of the tested equip-ment. ASME Performance Test Codes do not specify meansto compare those results to contractualguarantees. Therefore, it is recommended that before starting the test,

It is beyond the scope of any Code to determineor interpret how such comparisons shall be made.vFOREWORDIn 1966, the ASME Performance Test Code Comm
28、ittee recognized the need for a PerformanceTest Code for Large Incinerators. A Committee was formed in 1967 and charged with the taskof developing a comprehensive Test Code for Large Incinerators, a task to be followed by a ShortForm Test Procedure. This Committee was officially designated as PTC Co
29、mmittee 33 LargeIncinerators. At the time of its issue, PTC 33 represented the highest state of the art in incineratortesting. It was submitted to industry for trial use and comment in 1977. PTC 33 was approvedby the Performance Test Codes Supervisory Committee on June 30, 1978, and was approved asa
30、n American National Standard by the American National Standards Institute (ANSI) Board ofStandards Review on December 6, 1978.PTC 34 was formed in 1988 as a follow-up to PTC 33. PTC 33 was essentially a procedure fordetermining combustion efficiency and waste capacity and did not address units with
31、energyrecovery. At that time, it was recognized that the procedures for sampling tons of a heterogeneousmaterial were unrealistic and impractical as a key element of a waste combustion performancetest. At the urging of the ASME Research Committee on Industrial and Municipal Waste, theU.S. Bureau of
32、Standards now the National Institute of Standards and Technology (NIST)developed, over a period of about 10 years, a larger calorimeter but concluded that the largerone was not much better than the smaller one because of the sampling dilemma. This providedthe incentive to pursue the boiler-as-a-calo
33、rimeter method covered by this test Code.The 2007 edition of the Code was approved by the PTC 34 Committee on January 9, 2007, andby the Performance Test Codes Standards Committee on January 9, 2007. It was then approvedand adopted by the Council as a Standard practice of the Society by action of th
34、e Board onStandardization and Testing on February 20, 2007. It was approved by ANSI as an AmericanNational Standard on April 12, 2007.This updateof PTC34 doesnot includeany significantphilosophical orcomputational changes.It is more a clarification (i.e., we fixed typographical errors) of previously
35、 established procedures,and we added clarity and detail to aid the user in the determination of test uncertainty. It wasapproved by ANSI as an American National Standard on January 6, 2017.viASME PTC COMMITTEEPerformance Test Codes(The following is the roster of the Committee at the time of approval

40、 the Committee Page at go.asme.org/PTCcommittee.ixINTRODUCTIONThis Code contains instructions for testing waste fuelcombustion systems with energy recovery. These facili-ties are defined as combinations of apparatus for con-suming the organic content of waste by releasing itschemical energy. For the
41、 purpose of this Code, perform-ance will be a measurement of the available heat energyreleased during the process. The recovery of usefulenergy in the form of steam is considered to be themeasure of performance in this Code. It is not the intentof these testing procedures to obtain data on specificc
42、omponents of the system or to establish design criteriafor these components or the process. Testing of individ-ualcomponentssuchasfansshallbeconductedinaccor-dance with their respective test Codes. See ASMEPTC 11.Itisintended thatinusingthisCodea detailedexami-nation will be made of the Code of Gene
43、ral Instructions,ASME PTC 1, and all other Codes herein referencedbefore starting preparations for the tests. Such study isfor the purpose of ensuring an orderly and thoroughtesting procedure since it provides the user with anoverall understanding of the ASME Performance TestCode requirements and en
44、ables the tester to understandreadily the interrelationship of the various Codes. Careshould be exercised to obtain and use the latest revisionof the Codes.Subsection 5-20 of this Code is concerned with sym-bols and their description,relating specifically to testingof waste combustion systems. This
45、Code has departedfrom the use of symbols used in earlier Codes in anattempt to make the symbols compatible with currentword processors, personal computer spreadsheets, andcomputer code. Hence a symbol set was adopted thatdoes not use superscripts, subscripts, hyphens, or Greekletters.The ASME Supple
46、ments on Instruments andApparatus PTC 19 series referenced herein should bexstudied thoroughly, because the value of the test resultsdepends on the selection and application of the instru-ments,theircalibration,andtheaccuracyofthereadings.Other items of vital importance to the value of thetest are t
47、he proper determination of the characteristicsof the effluent gas and water streams. The appropriateprocedures for test and analysis as listed herein shouldbe followed carefully.This Code is intended as a test guide for all wastecombustor systems with energy recovery, but it couldnot possibly detail
48、 a test applicable to every variationin the design of waste combustion systems. In everycase, a competent engineer must study the particularfacility and develop test procedures that are inagreement with the intent, guiding principles, andrequired accuracy of this Code. Examples of the systemvariatio
49、nsatthetimeofpreparationofthisCodeincluderotary kilns, refractory and waterwall furnaces, rotarycombustors, mechanical grates, semi-suspension andsuspension burning, multiple-chamber solid hearthunits, and two-stage combustion systems. Such systemswere considered as the Code was being prepared.Portions of this Code may be used for waste combus-tors without energy recovery in the area of unburnedcombustibles in residue.Forsystemsfiredeitherbywasteorbywasteincombi-nation with other fuels in which heat recovery is a majorportion of the heat output, ASME PTC 4 may be used,along with a
