Makwiro’s BATEMAN electrostatic
precipitator refurbished
A major refurbishment to original condition of the BATEMAN-ELEX electrostatic
precipitator at Zimplats’ Makwiro mine in Zimbabwe was successfully
completed by BATEMAN within three months of receipt of order.
With inlet gas flow specifications of 14 775 Nm³/s
at 350 °C, the precipitator was online within two months, then insulated
and
commissioned after another month. The off-gas cleaning system at the
mine showed no visual emissions after refurbishment and is operating
well within design specifications.
The system comprises extraction ducting from the smelter
arc furnace and extraction ducting from two converters, with the two
ducting systems terminating tangentially in a common mixing chamber.
The gas temperatures are equalised and conditioned by means of ambient-air
ingress to achieve the designed precipitator-inlet temperature.
The original unit was designed and built by BATEMAN
and installed by a skilled crew from South Africa within tight deadlines.
BATEMAN-ELEX precipitators achieve reduced dust emission levels previously
only attainable using bag-houses.
