Alkali Metal Partitioning In A Pulverized Coal Combustion

Size segregated fly ash samples extracted from a 17 kW down-fired pulverized coal combustor showed strong evidence of alkali vaporization. The fraction of sodium in sizes smaller than 0.65 m f8A showed a correlation with acid soluble sodium divided by total silicates in the parent coal. Addition of silicates to coal reduced f8A for sodium.

Geochemical Partitioning From Pulverized Coal To Fly Ash

Nov 01, 2020 Highlights. Pulverized feed coal, fly ash, and bottom ash are examined. Arsenic captured by fly ash is dependent upon particle size, flue gas T, and particle mineralogy. Mercury capture depends on flue gas T and carbon amount, form, and rank of feed coal. Selenium capture largely depends upon flue gas T but aberrant behaviors are noted.
