Improvement of power plant efficiency due to higher steam condition is frequently foreseen to outbalance the carbon capture penalty. This work focuses on the conceptual design of two coal-fired power plants using CO 2 as working fluid: one with post- combustion MEA-based CO 2 capture and one with oxy-combustion CO 2 capture …

Pulverized coal plants are industrial or utility boilers that generate thermal energy by burning pulverized coal, which is coal that has been ground or broken into fine particles. This powdered coal is then blown into the firebox to ensure complete combustion and higher efficiency in steam generators.

Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of 0.5 % or less making the boilers very efficient.
