Ash Melting Behaviour


The ash melting behaviour of Eucalyptus and hybrid poplar tree partitions was examined as part of the Shortfor project, Working Package 1.

Higher slagging index values indicate a lower propensity for the formation of strong slagging deposits.

Generally, fuels with a slagging index less than 1150°C have a severe slagging potential, while values greater than 1340°C indicate weak slagging potential. Interim values cover a wide range of severe to moderate slagging potentials.


Rs < 1150°C
= Severe
1150 > Rs > 1340°C
= Moderate
Rs > 1340°C
= Weak
