The Properties of Cenospheres and the Mechanism of Their Formation During High-Temperature Coal Combustion at Thermal Power Plans

Abstract

A systematic analysis of the probable scenario of the supramolecular structure (texture) formation of mineral products, formed during the high-temperature combustion of pulverized bituminous coals at thermal power plants (TPP) is provided. The general physico-chemical consideration of the processes that occur at different stages (heating, burning, viscoplastic state in the hot zone, and cooling) during the combustion of bituminous coal makes it possible to allocate the following systematic transformations: coal → char → network structures (including plerospheres)→cenospheres→fly ash..
