Abstract: PAUL DISERENS.2 It is possible to define four different calorific values of a fuel, and the conversion of one into another, the high and the low value, at either constant pressure or constant volume, with appropriate experimental procedure.This was done by Cragoe of the Bureau of Standards in 1929.These values are physical properties of a fuel, and it seems proper that they should be established by the U. S. Bureau of Standards and accepted by engineers, especially for converting measures, weights, or volumes of fuel consumption per horsepower or kilowatt-hour into hourly heat rates, or thermal efficiencies.The selection of that one of the four possible calorific values and the details of procedure to be used in applying it in a thermalefficiency calculation might be standardized by the ASME Power Test Code Committee to be used for all sorts of fuels and powergeneration equipment, and adopted by all of the Subcommittee individual Codes.On the other hand, each of the several Subcommittees of the Power Test Code Committee might be allowed or instructed to select that one of the four possible calorific values which it considers most suitable, with the details of procedure in applying it.Under the first condition, all thermal-efficiency values for all sorts of power-generating plants and any fuel, would have the same basis, and be directly comparable.On the other hand, under the latter condition, those efficiency values which have a different basis would not be directly comparable but the conversion of any one to the equivalent for the basis of the other could be defined.1 This is a composite discussion presented in connection with the three papers which constitute the present Symposium on Heating Value of Fuels; they appear on pages 811-822 of this issue of the Transactions.
