The CAF G5 is a furnace designed to test ash fusibility, and optionally, the increasingly popular determination of biomass or solid recovered fuels testing.
The coal ash fusibility test furnace conforms to the Standards ISO 540:2008; ASTM D 1857 / D1857M – 18; DIN 51730:2007-09; DD CEN/TS 15370-1:2006 and PD CEN/TR 15404:2010 (solid recovered fuels (SRF)).
The CAF G5’s automatic and continuous recording of digital images allows laboratory technicians to carry out other tasks while the test is in progress, reviewing results later. The new CAF G5 greatly enhances the quality of the recorded images and test results increasing efficiency in laboratories.
The maximum temperature of 1600 °C enables both biomass and coal testing. An optional work tube integrated lighting system is also available when testing low ‘initial deformation’ temperature of SRF or biomass samples.
Standard features
- Determination of moisture in coal acc. to BS 1016-104.2:1991, BS ISO 687:2010 & BS ISO 11722:2013 (MFS/1 ISO) or ASTM D3173-11 (MFS/1 ASTM)
- 210°C maximum operating temperature
- {{LL::products.mfs.advantages.bullets.3}]
- Loading tray
- Side hinged door with gas tight seal & easy one handed operation
- Flow meters to monitor gas flow & chamber seal integrity
Options (specify these at time of order)
- Welded steel desiccator with provision for a nitrogen flow which is used as a cooling vessel. The crucibles can be transferred into the desiccator without the need for cooling on a metal plate.
