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 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.

An estimate is made as to how closely different laboratories can check in calculating fusibility of coal ash, how well duplicate determinations by the same laboratory will check, and how the results with the De Graaf furnace compare with those of the standard gas-furnace method of the American Society for Testing Materials.

LECO's AF700 is an ash fusibility determinator that automatically monitors ash cone deformation temperatures in coal ash and coke ash. Prepared ash cones are mounted on a ceramic tray and placed into a high-temperature, rampable furnace. The user selects an analytical method with a predefined furnace atmosphere (oxidizing or reducing) and a ...

The Fusibility of Coal Ash NEW DESIGN OF PLATINUM-WOUND FURNACE In the operation of large solid-fuel boiler installations the fusion characteristics of the coal or coke ash are an important factor. If fusion and coagulation of the ash occur, trouble will be met in the raking of the boiler and serious blockages may result. Standard

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.

measures of the fusibility of the average ash of the coal, more par-ticularly those fusibilities given by the A.S.T.M. standard gas-furnace method because of its more general use. Owing to the com-plexity of the reactions that affect clinker formation, there is no assured reason for predicting what common fraction of the total

and coal testing. An optional work tube integrated lighting system is also available when testing low 'initial deformation' temperature of SRF or biomass samples. The original CAF Digital was designed by Carbolite Gero to test ash fusibility of coal, biomass and solid recovered fuels to determine sintering, melting and flow temperatures.

The ash fusibility is one of the vital measurement to test the high temperature characteristic of coal. It is an important indicator of coal, which reflects the dynamic change of mineral matter in boiler. Therefore, testing ash fusion temperatures of coal plays a critical role to ensure the safe and economic operation of boiler in coal-fired power plants. Firstly, ash fusibility test can ...
