Sainmhíniú solid combustible residue that remains after a coal particle is heated and the volatile matter is expelled Tagairt "'Fixed-carbon content'. Encyclopaedia Britannica > Coal > Coal rank, https://www.britannica.com/topic/coal-utilization-122944#toc81702 [30.6.2017]"
Nóta "The fixed-carbon content of a coal is determined by subtracting the percentages of moisture, volatile matter, and ash from a sample. Since gas-solid combustion reactions are slower than gas-gas reactions, a high fixed-carbon content indicates that the coal will require a long combustion time. Reference: 'Fixed-carbon content'.

Nóta La composition chimique est caractérisée par une teneur en hydrogène (4%) moitié de celle des pétroles. La teneur en carbone sur sec varie de 55% pour les lignites, à 70% pour les bitumineux et 90% pour les anthracites.
