Processed Low NOx Fly Ash as a Filler in Plastics

Fly ash generated from low NOx burners at American Electric Power's Glen Lyn facility was beneficiated to remove residual carbon, magnetic particles, and cenospheres. The clean fly ash had a mean particle size of about 30 microns, which is coarser than typical commercial fillers used in plastics. To obtain a finer sized fly ash, air classification was used to separate the clean fly ash into its...

Using a Novel Fly Ash Based Calcium Silicate as a Potential Paper Filler

A novel calcium silicate filler can be made from fly ash. This new filler, known as fly ash based calcium silicate (FACS), has a highly porous surface structure, high brightness (91% ISO), low bulk density (0.31 g/cm 3 ), and high specific surface area (121 m 2 /g). In this paper, its potential application as a paper filler was studied and its effect on drainage, retention, and paper properties...

Chemical Reaction of Fly Ash

In a previous paper, Brouwers and Van Eijk [1] presented a theoretical study on the dissolution (reaction) of pulverised powder coal fly ash. This fly ash was modelled as hollow spheres, and a shrinking core model was derived for these hollow spheres that contain two regions (an outer hull and an inner region). The obtained analytical equations were applied to the dissolution experiments by Pie...
