Carbolite Gero CAF G5 Coal Ash Fusibility Furnace

The CAF G5 features a 79mm internal diameter work tube that can test up to eight samples simultaneously, with a maximum temperature of 1600°c. 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 complete with integrated PC and firmware.

Lightweight insulation allows for fast cooling, allowing multiple tests to be run in a day. Six silicon carbide elements provide heating.

Designed to test coal ash fusibility characteristics of the fuel and optionally the determination of biomass or solid recovered fuels testing and conforms to standards: ISO 540:2008; ASDTM 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). A work tube with inbuilt lighting system is an option when testing low initial deformation temperature of SRF or biomass samples.

When coal is combusted in a power plant’s furnace the heat is generated is sufficient to melt its ash which when cooled solidifies into a powder-shaped residue or a glassy slag (clinker) forms and must be removed, large coal furnaces suffer from clinker build-up with 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 simulate coal ash behaviour as closely as possible when heated in either a reducing or an oxidising atmosphere, giving data indicating temperatures for sintering, melt and flow.

Features

  • Default software settings and individual analysis form for coal ash, biomass and SRF
