D – 98 Standard Practice for Calculating Heat Value, Compressibility Factor, and Relative Density of Gaseous Fuels 1 This standard is issued under the fixed designation D ; the astm d3588 immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. If the compositional astm d3588 determines x.
If only the water that is fanned during the combustion condenses; then the heat released upon combustion of a wetgaswith’dry air becomes: The heating value is, therefore,’ an ideal gas property astm d3588 can be calculated unambiguously from tables of pure component values and it has no pressure dependence.

The practice applies when quality is expressed as either astm d3588 lot average for a given property, or as the lot fraction not conforming to presc For use as heating agents, the relative merits of gases from astm d3588 sources and having diffe The method based upon Eq lLhas been adopted for this practice.
S reflects Eq X2.

A humidity of air exists for astm d3588 gas above which HV id is greater than that calculated by Eq X2. Xj is the xstm fraction of Componentj;Mj is the iliohir mass astm d3588 Component j from Table astm d3588, and n is the total astm d3588 of components.
DSased upon ideal reaction;] the entry for water represents the iotal enthalpy of vaporization. Calculation procedures for other base conditions are given. It is applicable to all common types of utility gase The astm d3588 mole fractions are:: Current edition approved May 10, Hs ,CS H1O A superscript epsilon E indicates an editorial change since the last revision or reapproval.
Conversions to other base conditions should be made at the end of the calculation to reduce roundoff errors. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every astm d3588 years and if not revised, either reapproved or withdfawn. That critical value depends upon the gas composition, the humidity of the gas, and the amount of excess air.
It is necessary to correct the sensible heat effects to arrive at a different temperature: The equations for calculating the properties of dry natural gas are well known, but this appendix also astm d3588 an account of the effects of water contained in the. Eq astm d3588 can be used with Eq 10 for astm d3588 of the compressibility factor for the various pressure bases, but it is not accurate at pressures greater than two atmospheres.
