Where:
HT = Net heating value of the sample, MJ/scm; where the net enthalpy per mole of offgas is based on combustion at 25 °C and 760 mm Hg, but the standard temperature for determining the volume corresponding to 1 mol is 20 °C;
K = Constant, 1.74 * 10-7 (1/ppm) (g mol/scm) (MJ/kcal) where standard temperature for (g mol/scm) is 20 °C;
Ci = Concentration of sample component i in ppm on a wet basis, as measured for organics by Reference Method 18 in 40 CFR part 60 and measured for hydrogen and carbon monoxide by ASTM D 1946-82 (incorporated by reference as specified in § 260.11 ); and
Hi = Net heat of combustion of sample component i, kcal/9 mol at 25 °C and 760 mm Hg. The heats of combustion may be determined using ASTM D 2382-83 (incorporated by reference as specified in § 260.11 ) if published values are not available or cannot be calculated.
Log10(Vmax) = (HT + 28.8)/31.7
Where:
28.8 = Constant,
31.7 = Constant,
HT = The net heating value as determined in paragraph (e)(2) of this section.
Vmax = 8.706 + 0.7084 (HT)
Where:
8.706 = Constant,
0.7084 = Constant,
HT = The net heating value as determined in paragraph (e)(2) of this section.
