34、ave been, or will be, replaced by them. 5 Basis of reporting results 5.1 General The analyses described in BS1016-6 to BS1016-11 (BS 1016-106 in the new series), BS 1016-21 (BS1016-103 in the new series), BS 1016-104, BS1016-105 and BS 1016-106.4.1 are carried out on samples of coal or coke that hav

35、e been ground to pass a2124m test sieve conforming to BS410:1986 and air-dried to approximate equilibrium with the laboratory atmosphere. For certain purposes it is necessary to report results on some other basis e.g. as follows: as received dry dry, ash-free dry, mineral-matter-free The methods of

36、converting results to these other bases are described in5.2 to 5.5. The analysis of the pure coal substance, which is of particular importance for the classification of coals, is that expressed on the dry, mineral-matter-free basis and so the estimation of mineral matter is discussed in5.5. The calo

37、rific value of a fuel determined in the laboratory is the gross calorific value at constant volume (see Part105). Methods for calculating the gross calorific value at constant pressure, as well as the net calorific values at constant volume and at constant pressure are described in5.6. The reporting

38、 of results for the methods described in BS1016-14, BS1016-15, BS1016-17, BS1016-18 and BS1016-20 (BS 1016-114, BS 1016-113, BS1016-109, BS 1016-110 and BS 1016-112 respectively in the new series) and BS1016-107, BS1016-108 and BS1016-111 is covered comprehensively in the respective Parts. 5.2 Calcu

39、lation to other bases Almost all analytical values can be converted from any given basis to another basis by multiplying them by the appropriate formula shown in Table 2 after insertion of the numerical values for the symbols. The formulae in Table 2 are exact and simple to use, but for some convers

40、ions to the dry, ash-free and the dry, mineral-matter-free bases, the corrections indicated in5.4 and5.5 may be necessary. NOTECarbon dioxide from carbonates, total sulfur content, pyritic sulfur content, sulfate sulfur content, phosphorus content and arsenic content are not reported on the dry, ash

41、-free or the dry, mineral-matter-free bases as the terms are not applicable to these determinations. 5.3 Dry basis When coal analyses are converted to this basis, the effect of a factor that is partly dependent on the laboratory atmosphere is removed. For coke analyses, the analysis sample is usuall

42、y prepared from the dried sample of coke passing a13.2mm test sieve after the determination of total moisture content in accordance with BS1016-2. Finely ground coke is extremely hygroscopic and can absorb up to2% (m/m) of moisture. Therefore, if a significant period of time elapses between preparat

43、ion of the sample and its analysis, its moisture content should be determined and the results of the analysis corrected to the dry basis using the appropriate formula. However, if the analysis is carried out within a short time of the sample being prepared, only a small amount of moisture will be pi

44、cked up, and the moisture content on the air-dried basis (M ad ) will be small and the conversion factor will be close to unity. 5.4 Dry, ash-free basis The dry, ash-free basis is a hypothetical condition in which the coal or coke is assumed to be free of both moisture and ash.

The formula may also be used for

46、the volatile matter content of most coals. For anthracites and coals of low volatile matter content that also have a high carbonate content greater than2% (m/m), it is necessary to make allowance for the carbon dioxide evolved during the determination of the volatile matter content and the following

47、 equation is used. When reporting organic carbon content on this basis, it is necessary that the carbon present as carbonate is deducted from the total carbon content and the calculation for this is given by the following equation. 5.5 Dry, mineral-matter-free basis 5.5.1 General The dry, mineral-ma

48、tter-free basis is a hypothetical condition, corresponding to the concept of pure coal or coke substance. Since the dry, ash-free basis for coal ignores the changes in mineral matter when coal is burnt, the dry, mineral-matter-free basis is preferred whenever the mineral matter content can be calcul

49、ated (see5.5.2), even if some analytical values have to be assumed in the absence of results determined on the sample. In the case of coal in the dry, mineral-matter-free state, it is considered to be free of both moisture and the various minerals associated with the coal when sampled. Coke on the same basis is considered to be free of both moisture and substances formed during the coking process from the minerals present in the coal charge. The formulae
