Ash Fusion Analyzer- IF2000G Series

Overview of Ash Fusion Analyzer

Uses the Latest technology in the service of the fusion temperature determinations Sylab Ash Fusion Analyzer automatically determines four critical temperatures: Deformation Temperature, Softening temperature, Hemispherical Temperature and Fluid Temperatures. It is a Fully automatic instrument for determining the Ash Fusion points by means of Image analysis. Sylab’s Ash fusion analyzer uses modern technology for monitoring, computing, and storing results and curves obtained during the test. Up to 6 samples can be analysed in each batch.

Typical Sample Materials

Theory of Operation

During combustion of samples like Coal, Coke, Biomass and Refuse derived fuel, the remaining non-combustible material becomes ash or liquid slag. Ash Fusion Analyzers are used to determine ash cone deformation temperatures. The ash cones change shape in response to increasing heat. Temperatures are recorded for different stages in the shape changes, which, in order of increasing heat, are called : Initial deformation temperature (IT), Softening temperature (ST), Hemispherical Temperature (HT) and Fluid Temperature (FT). The behaviour of the Ash residue at high temperatures is a critical factor in selecting the suitable fuel for boilers and furnaces.

Ash Fusion temperature is measured at 4 points or stages of heating, by observation of the behaviour of triangular Pyramids, Cones, Cylinders prepared from ash when heated at a specific rate in a controlled atmosphere.

The Ash Fusion Analyzer determines the behaviour of fuel ash in combustion, gasification, liquefaction and ash utilization. The characteristics of fuel ash for its tendency to slag and foul have been traditionally related to the bulk chemistry of the ash and ash fusion temperatures. It can cause slagging or clogging problems on combustion chamber and pipe surfaces and decline heat transfer efficiency. It is said that the operating temperature should be below the fluid temperature (FT). Thus, it is necessary to study the Ash Fusion Analyzer not only theoretically, but also for practical application.

The Higher the fusion temperatures of the fuel-ash, the lower the tendency of the ash to slag in the combustion chamber of boilers.

Ash Fusion temperatures are often cited in fuel specifications for boilers, because they are believed to be a measure of the tendency of Coal Ash to form clinkers.
