Pulverised Coal Combustion - an overview ScienceDirect ...

These technologies are seen as a major carbon mitigation route, as it is estimated that a percentage point increase in plant thermal efficiency can lead to a double reduction in CO 2 emissions [17]. Therefore, replacing old pulverized fuel (PF) plants with SC pulverized coal plants has the potential of reducing emissions by 10–25% [15].
