Ash Fusion, Coal Analysis, Kentucky Geological Survey ...

Ash fusion, also called fusibility, is a test to determine how the ash residue remaining from combustion of a coal will react in a furnace or boiler. In this test, coal ash is put into conical molds as specified in ASTM method D1857-04 guidelines and procedures (American Society for Testing and Materials, 2013, p. 431–435).

Carbolite CAF G5: a new generation of ash fusibility furnaces

Carbolite Gero CAF G5: a new generation of ash fusibility furnaces. When coal is combusted in the furnace of a power plant a powder-shaped residue or a glassy slag (clinker) forms and must be removed. Large coal furnaces suffer from clinker build-up and therefore expensive maintenance due to closure for removal of clinker.

Fusibility - an overview | ScienceDirect Topics

The fusibility of coal minerals can be expressed as a function of the content of the principal oxides occurring in the ash, namely: SiO 2, Al 2 O 3, TiO 2, Fe 2 O 3, CaO, MgO, Na 2 O, and K 2 O (Seggiani, 1999; Alpern et al., 1984). The acid/base ratio is the most frequently used parameter for correlating ash fusibility with its composition.
