Theory of Operation

During combustion samples like Coal, Coke, Biomass, Refuse derived fuel, the remaining non-combustible material becomes  ash or liquid slag. Ash Fusion analysers 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 temperature 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 has 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 for not only theoretically, but 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 specification for boilers, because they are believed to be a measure of the tendency of Coal Ash to form clinkers.
