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 ...

In this study an Inverted Reflux Classifier, a combination of parallel inclined channels and a vertical fluidized bed, was used for the first time to recover and concentrate cenospheres from a real fly ash feed obtained from a coal fired power station.

Can density based coal processing techniques be applied …

The reflux classifier uses a set of inclined channels within a hin dered bed type settler to suppress the effect of size on separation. The current study applies theoretical models for both the hindered and reflux classifier to a characterised CFA feed, to investigate the potential for utilising separators of this type

A Pilot Scale Study of Cenosphere Recovery and ...

A pilot scale Inverted Reflux Classifier was used to separate cenospheres from fly ash waste, following successful studies at a laboratory scale (Kiani et al., 2014, Kiani et al., 2015). The product grade and the cenosphere recovery responded to changes in the feed split ratio in accordance with the earlier study.

Char samples are prepared in a drop tube furnace (DTF) in a nitrogen atmosphere using density-separated coal samples of two Australian coals. The structure and morphology of the char samples are analyzed under a scanning electron microscope (SEM). The porosities of individual chars are determined through image processing of the SEM images. The char particle size distribution (PSD) is analyzed ...

Maceral separation from coal by the Reflux Classifier. The Reflux Classifier (RC) is a separation technique which has been used in the coal and mineral processing industries. It uses water as a medium, and is therefore a suitable preparation device for studies on coking coal as other separation techniques may change coking properties.
