Combustion of Coal and Coal Slime in Steam-Air Environment and in Slurry Form
Energies, 2022 One of the ways to minimize anthropogenic emissions from coal combustion is to replace conventional schemes used for the introduction of coal dust into the furnaces of power plants through the injection of water-containing fuels. In this research, the three most promising schemes for fuel combustion were implemented: (i) the simultaneous introduction ...
