Abstract: | Experiments have been carried out to assess the effect of ammonia injection upstream of a small-scale fabric filter which collects ash from the burning of coal in Australia. The ammonia injection resulted in an increase in the pressure drop across the filter. This was apparently due to an increase in the cohesivity of the ash, which made dislodgement during cleaning more difficult. There were some indications that the ammonia-conditioned ash formed a more porous dust cake during the filtration cycle. |
