Effect of flotation on coal combustion

The selection of coal for use in pulverized coal fired boilers has been based largely on coal rank and proximate analysis. However, Nandi et al. have shown that combustion efficiencies of various coal samples mainly depend on the presence of inert coal macerals, e.g. semifusinite, fusinite and oxidi...

Description
Summary:The selection of coal for use in pulverized coal fired boilers has been based largely on coal rank and proximate analysis. However, Nandi et al. have shown that combustion efficiencies of various coal samples mainly depend on the presence of inert coal macerals, e.g. semifusinite, fusinite and oxidized vitrinite. It appears, therefore, that the characterization of ignition and combustion properties of floated fractions of coal which may contain specific maceral components is essential for determining the overall thermal efficiency of the cleaned coal. This note presents data on the viscosity and ignition delay measurements of coal which was cleaned using the froth flotation technique.
