Digital Coal Ash Fusibility ( fusion) Furnace ( CAF)

Digital Coal Ash Fusibility ( fusion) Furnace ( CAF) Product : Carbolite - England At high temperatures, the heat from burning coal is often sufficient to melt its own ash which, when cooled, solidifies into clinker. In industrial coal burning applications, clinkers can be extremely large and can cause both disposal problems and operation downtime. Coal ash fusibility testing is therefore required to determine the ash fusibility characteristics of the fuel. The introduction of the Carbolite digital Coal Ash Fusibility ( fusion) test furnace has revolutionised coal sample testing where time and accuracy are both critical; The coal ash fusion furnace is designed to heat coal ash samples to a maximum temperature of 1600° C in a controlled atmosphere; Up to 12 samples can be simultaneously tested; Visually records the fusion samples for further analysis; Furnace work tube is sealed and has a fail-safe gas control system for use with toxic & flammable gases; Sliding & rotating door mechanism provides unrestricted access to work tube for loading/ unloading samples; Maximum number of samples : 12; Digital data capture.
