The Carbolite Gero CAF G5 Coal Ash Fusibility Furnace replaces previous model CAF Digital.

The CAF G5 features a 79mm internal diameter work tube that can hold at least six samples simultaneously. The maximum temperature is 1600c. The software supplied digitally records the tests, with automatic and manual settings so tests can be executed without supervision and reviewed later.  The software has zoom facilities for test analysis and can set temperature supplied with integrated PC and firmware.

During the industrial burning coal heat melts ash causing residue on cooling that solidifies into clinker. These clinkers can be large, causing shutdowns and waste disposal issues. Coal ash fusibility testing determines the ash fusibility characteristics of the fuel.  The furnace conforms to standards ISO 540:2008; ASTM D 1857 / D1857M – 04 (2010); DIN 51730:2007-09; DD CEN/TS 15370-1:2006 (biomass) and PD CEN/TR 15404:2010 (solid recovered fuels (SRF). Also suitable for biomass or solid recovered fuels testing. A work tube with inbuilt lighting system is an option when testing low initial deformation temperature of SRF or biomass samples.

The furnace features lightweight insulation for fast cooling allowing multiple tests to be run in a day. Integral Silicon carbide elements provide heating.
