Particle Size Distribution as a Nonindependent Variable

The particle size distribution (PSD) is critical for pulverized-coal combustion in coal-fired power-plant boilers. However, the PSD might not necessarily be an independent variable in combustion analysis. Using industrial-scale combustion tests in a coal-fired power plant, this work aimed to explore the relationship between the PSD of pulverized coal and coal properties and to understand the

Size Distribution of Fine Particles from Coal Combustion

Measurements of the particle size distribution at the outlets of six coal-fired utility boilers showed a peak at a particle diameter near 0.1 micrometer. This submicrometer mode appears to be a general feature of coal combustion that results from a volatilization-condensation process in the boiler. At the boilers tested, the submicrometer mode contained 0.2 to 2.2 percent of the total fly ash
