Abstract
Bed materials processing involves solid minerals reduction to sizes of
about 100-600pm and density of about 1400-3000 kg/m". Apart from
the physical criteria, the chemical properties were also essential in
respect of its absorbent and agglomeration effects in the fluidized bed
combustor. In this work, we present the process technology to produce
and select bed materials from Nigerian solid minerals. Firstly, the
chemical composition of the various processed bed materials were
determined using wet chemical method. Secondly, we subjected the
materials at 100um to dustiness test which provided the proportion
trapped by the cyclone and filter. Nigerian bed materials were high in
qualities and they met the requirements of fluidized bed combustion
technology.
