| Abstract | In this study, two new/unconventional spouted bed reactor designs have been
compared with the conventional design having a central gas (air) inlet jet. In one
of these designs, air is introduced into a rectangular column through a rectangular
slit while in the other design air is introduced into a cylindrical column through
a circular slit. The column and the air inlet areas were the same in all the designs
compared.
Tests, carried out with dry sand samples, displayed hysteresis typical of all
spouted beds with characteristic differences in shape depending upon particle size.
Effects of particle size, bed weight and column geometry were evaluated. The
maximum pressure drop was obtained in the design with circular slit and the
minimum in the design with rectangular slit.
Experiments were carried out to determine the contact efficiency, mass transfer
flux, and combustion efficiency loss due to CO formation for the different reactor
designs. The contact efficiency based on gas (air) exit and bed temperature, and
combustion efficiency loss due to CO formation showed similar results and it was
found that the highest contact efficiency and lowest co loss was achieved in the
design with circular slit and lowest contact efficiency and highest CO loss was
achieved in the design with rectangular slit. Mass transfer flux was found to
decrease with increasing particle diameter and it was maximum in the design with
central jet and minimum in the design with circular slit. |
