The heat content rates (i.e., thermal conversion factors) provided in this section represent the gross (or higher or upper) energy content of the fuels.
In general, the annual thermal conversion factors presented in Tables A2 through A6 are computed from final annual data or from the best available data and labeled "preliminary." Often, the current year's factors are labeled "estimate," and are set equal to the previous year's values until data become available to calculate the factors.
The dose conversion factors
calculated for monoenergetic gamma-rays from 0.011 to 10Mev strongly agreed with those of Korcher and Sjoreen, 1985 and those of Chen, 1991 reported values, particularly at energies above 0.049MeV.
Once the conversion factors
are determined, the Print Fee Schedule option can be selected from the main menu and the CPT codes to be included in the personalized schedule entered.
In rural areas, particularly for specialty procedures, payments defaulted to a minimal conversion factor
times a relative value developed independently by each intermediary carrier.
Assumed by EIA to be 6.000 million Btu per barrel or equal to the thermal conversion factor
for Still Gas.
A conversion factor
will be applied each year to update the fee schedule.
* 2009 forward: Calculated by EIA as the annual quantity-weighted average of the thermal conversion factors
for undenatured ethanol (3.539 million Btu per barrel), pentanes plus used as denaturant (4.620 million Btu per barrel), and conventional motor gasoline and motor gasoline blending components used as denaturant (5.253 million Btu per barrel).
In general, the annual thermal conversion factors
presented in Tables A2 through A6 are computed from final annual data or from the best available data and labeled "preliminary." Often, the previous year's factor is used as a preliminary value until data become available to calculate the factor appropriate to the year.
The source of each factor is described in the section entitled "Thermal Conversion Factor
Source Documentation," which follows Table A6 in this appendix.
For "BiomassBased Diesel Fuel" and "Other Renewable Fuels," EIA assumed the thermal conversion factor
to be 5.359 million Btu per barrel or equal to the thermal conversion factor
