Ultrasonic Coal-Wash for De-Ashing and De-Sulfurization

Part of the book series: Springer Theses ((Springer Theses))

Abstract

This review addresses work on effect of burning high-ash and high-sulfur coal within the boiler equipment and environment. Within the boiler equipment, erosion of boiler accessories due to coal fly-ash impaction is reviewed, along with: ultrasound-assisted particle breakage; application of ultrasound in various fields; some of the patented ultrasonic coal-wash process for de-ashing; existing conventional chemical-based de-sulfurization methods and their demerits relative to ultrasonic methods; mechanism of ultrasound in aqueous medium and its contribution towards high-sulfur coal de-sulfurization; and, ultrasound-assisted high-sulfur coal and high-sulfur diesel fuel de-sulfurization already initiated by other researchers.
