Carbon Dioxide Emission Factors for Coal

There were differences in the carbon-to-heat-content ratios between washed or partially washed and raw coal, but with a R 2 value of 0.06, the differences did little to explain the variation in the ratios. Therefore, no data correction was warranted to account for the small effect that coal cleaning had on emission factors.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.

Typical coal and nuclear plants operate at capacity factors between about 60% and 80%. For a plant with a conversion efficiency of 33%, an electrical output of 1 GWyr (3.15 x 10 16 J) corresponds to a thermal output of 9.5 x 10 16 J, or 0.090 quad. Thus, typically, the relation between primary energy used and electricity produced is approximately:
