Detailed information is available in our dedicated Coal, Coke & Iron Ore Testing Furnaces brochure (please download above). Carbolite Gero has developed a range of coal and coke testing furnaces and ovens for proximate analysis to qualitatively assess or, quantitatively measure, the amount of moisture, ash, volatile matter and fixed carbon in coal samples. Other products are also available for the determination of coke reactivity, iron ore reducibility, ash fusibility, swelling number index, expansion and contraction of coal and caking properties.

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 – 04 (2010); DIN 51730:2007-09; DD CEN/TS 15370-1:2006 (biomass) 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.

The CAF 16/38 is designed to test coal ash fusibility according to BS ISO 540:2008. The CAF 16/38 requires manual observation and recording of the transition points. In addition, a CAF furnace with automated digital image capture and archiving using Windows compatible software, the Coal Ash Fusibility Test Furnaces CAF G5, is available.

The VMF is specifically designed for testing the volatile matter of coal.

The SNF furnace is designed to test the swelling index number of coal in accordance with the following standard test methods. BS 1016-107.1:1991 Methods for analysis and testing of coal and coke. Caking and swelling properties of coal. Determination of crucible swelling number.

CDHT (Coal Drying High Temperature) and CDLT (Coal Drying Low Temperature) ovens are suitable for drying coal in accordance with the following standards: ASTM D2691 – 01, ASTM D2961 – 01a, ASTM D2961 – 02, ASTM D2961 – 95a, ASTM 3302 / D3302M-10, BS 1016-102:2000, BS 1016-1:1973, BS ISO 13909-1:2001, BS ISO 13909-2:2001.
