1、Designation: D 3176 89 (Reapproved 2002)Standard Practice forUltimate Analysis of Coal and Coke1This standard is issued under the fixed designation D 3176; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

2、A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the term ultimate analysis as it isapplied to the analysis of coal and coke. The informationderived is intended

3、 for the general utilization by applicableindustries, to provide the basis for evaluation, beneficiation, orfor other purposes.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish a

4、ppro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.3 The values stated in SI units are to be regarded as thestandard.2.

Terminology3.1 Definitions:3.1.1 ultimate analysisin the case of coal and coke, thedetermination of carbon and hydrogen in the material, as foundin the gaseous products of its complete combustion

9、 thedetermination of sulfur, nitrogen, and ash in the material as awhole, and the calculation of oxygen by difference.NOTE 1The determination of phosphorus or chlorine is not bydefinition a part of the ultimate analysis of coal or coke. See Test MethodD 2361 for the determination of chlorine and Te

10、st Methods D 2795 for thedetermination of phosphorus.NOTE 2Moisture is not by definition a part of the ultimate analysis ofcoal or coke but must be determined in order that analytical data may beconverted to bases other than that of the analysis sample.NOTE 3Inasmuch as some coals contain mineral ca

11、rbonates, andpractically all contain clay or shale containing combined water, a part ofthe carbon, hydrogen, and oxygen found in the products of combustionmay arise from these mineral components.4. Significance and Use4.1 Summarizing the ash content and the content of theorganic constituents in a sp

12、ecific format under the heading,Ultimate Analysis, provides a convenient and uniform systemfor comparing coals or cokes. This tabulation used with that ofProximate Analysis (Practice D 3172) permits cursory valua-tion of coals for use as fuel or in other carbonaceous processesand of cokes for metall

13、urgical purpose.5. General Requirements5.1 Coal sample collection shall be in accordance withPractice D 2234, and sample preparation shall be in accordancewith Method D 2013. Coke sampling and preparation shall bein accordance with Practice D 346.6. Specific Requirements6.1 Carbon and HydrogenThe ca

14、rbon and hydrogen de-termination shall be made in accord with Test Methods D 3178or D 5373.6.2 SulfurThe sulfur determination shall be made inaccordance with Test Methods D 3177 or D 4239.1This practice is under the jurisdiction of ASTM Committee D05 on Coal andCoke and is the direct responsibility

17、or determining oxygen, it shall be calculated bysubtracting from 100 the sum of the other components of theultimate analysis. The result so obtained is affected by errorsincurred in the other determinations of the ultimate analysisand also by the changes in weight of the ash-forming constitu-ents on

18、 ignition. By definition, oxygen calculated as a weightpercentage of the analysis sample according to this proceduredoes not include oxygen in the mineral matter or in the ash, butdoes include oxygen in the free water (moisture) associatedwith the analysis sample. See Section 7 of this practice forc

19、alculating and reporting results on other bases.6.6 MoistureThe moisture determination shall be made inaccordance with Test Method D 3173 or Test Methods D 5142.7. Calculation and Report7.1 The results of an ultimate analysis may be reported onany of a number of bases, differing from each other in t

20、hemanner by which moisture is treated.7.2 To avoid ambiguity and provide a means for conversionof data to bases other than the reported basis, it is essential thatexcept for data reported on a dry basis, an appropriate moisturecontent be given in the data report.7.3 It is recommended that, for data

21、reported on the as-received basis (or any other moist basis), a footnote or someother means be ussed in the report to indicate whether thehydrogen and oxygen values reported do or do not include thehydrogen and oxygen in the free water (moisture) associatedwith the sample.7.4 Procedures for converti

22、ng ultimate analysis sample datato other bases are presented in Table 1.7.4.1 Hydrogen and oxygen on the as-determined basisinclude hydrogen and oxygen in free water (moisture) associ-ated with the analysis sample. However, hydrogen and oxygenvalues reported on other moisture-containing bases may be

23、reported either as containing or as not containing the hydrogenand oxygen in water (moisture) reported on that basis. Alter-native conversion procedures are shown in Table 1.7.5 An example of ultimate analysis data tabulated for ahypothetical coal on various bases is given in Table 2.8. Precision8.1

24、 The permissible differences between two or more deter-minations shall not exceed the values listed in the precisionsection of the specific test method for the parameter deter-mined.TABLE 1 Procedures for Converting As-Determined Values to Other BasesAReporting BasisParameterBAs-DeterminedCDryAs-Rec
