The following sections list mathematical formulas that are used to calculate results
of measurements. The calorimeter system acquires the data required for the meas-
urements partially during the combustion process and the data is partially the results
of analyses of examination on fuel samples or on combustion products. The calcula-
tions correspond to the applicable standards (DIN 51900, ASTM 240D, ISO 1928,
BSI) for gross calorific values and net calorific values.
The following indices are used for the various reference states:
raw - supply state
an - analysis moist or air dry
waf - water and ash free
Section 17.9 contains an alphabetical list with the meanings of the formula symbols.
