Abstract:

There is increasing interest in the use of low cost biomass fuels for combustion, and in the differences in the effects that the fuels have in terms of ash deposition, leading to slagging and fouling and corrosion. The objective of the present study is to examine ash deposition of pulverised olive residue and palm kernel expeller onto stainless steel grade 316, when combusted in a laboratory drop tube furnace. Relation of these results to those found in large scale studies can provide validation for determining large scale ash deposition behaviour using laboratory apparatus. Samples of deposited ash and steel were collected at 1100, 1200 and 1300ºC. Ash samples were analysed to determine the proportion of burn­out occurring after deposition, and the steels and steel­biomass boundary were analysed using Focussed Ion Beam Scanning Electron Microscopy (FIB­SEM) techniques.
