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.
Caracteristici standard
- Analysis software which can be used in fully automatic or manual modes for coal ash samples and manual only for biomass and SRF samples.
- Software zoom function to enable accurate post-test analysis of individual samples with improved resolution
- One configurable grid assigned to each test piece
- Temperature controller program set up within the software
- Space saving embedded computer with Windows IoT Enterprise software runs future proof firmware
- Default software settings and individual analysis form for coal ash, biomass and SRF
- An optional work tube integrated lighting system when testing low initial deformation temperature of biomass or SRF samples
- Lightweight insulation allows quick cooling permitting multiple tests to be completed during the day
- Automated digital image capture of samples. The frequency of images recorded is set by customer preference, from every 1 °C increment to every 20 °C. The maximum interval for auto analysis is 5°C.
