The Carbolite CAF G5 is a furnace designed to test ash fusibility and, optionally, the increasingly popular determination of biomass or solid recovered fuels testing.
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 dramatically enhances the quality of the recorded images and test results, increasing laboratory efficiency.
The maximum temperature of 1600 °C enables both biomass and coal testing. An optional work tube integrated lighting system is also available when testing the low ‘initial deformation’ temperature of SRF or biomass samples.
The coal ash fusibility test furnace conforms to the 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)).
- 79mm internal diameter work tube
- Integral SiC elements
- 3508P1 automatic temperature programmer (20 segments) with multiple PID control
- Software zoom function to enable an accurate post-test analysis of individual samples with improved resolution
- One configurable grid is assigned to each test piece
- Analysis software which can be used in fully automatic or manual modes
- Temperature controller program is set up within the software
- Space-saving embedded computer with Windows OS
