Particle Size Distribution as a Nonindependent Variable

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 ...
