Proximate & ultimate analysis of coal
1. Fixed carbon from proximate analysis is a different
value than total carbon from ultimate analysis.
Total carbon includes some organic carbon that
escapes as volatile matter emissions during
combustion.
Fixed-carbon content increases with rank, and is used
to define ranks above medium-volatile bituminous
coal.
