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. If the fusibility characteristics are known, control of temperature can avoid clinker formation. Ash fusibility testing is designed to ...
