Cenosphere - Wikipedia

Etymology. The word cenosphere is derived from two Greek words, κενός (kenos: hollow, empty) and σφαίρα (sphaira: sphere), literally meaning "hollow sphere.". Production. The process of burning coal in thermal power plants produces fly ash containing ceramic particles made largely of alumina and silica.They are produced at temperatures of 1,500 to 1,750 °C (2,730 to 3,180 °F ...
