Duvha Power Station. Covered conveyer belt delivering coal from a mine to the Duvha coal-fired power station, Witbank, Mpumalanga, South Africa. In 1993 Duvha Power Station was the first power station in the world to be retrofitted with pulse jet fabric filters on three of its six units. These filters reduced air pollution by removing 99.9 percent of the fly ash produced by the power station, which would otherwise be released into the air through the chimneys.
