13. Electrostatic Precipitator
Each boiler has three precipitators which contain high voltage electrodes, these attract the dust or pulverised fuel ash (PFA) from the flue gases. At regular intervals the electrodes are rapped with motor-driven hammers and the PFA falls into hoppers below. In a year we would expect to produce 1.4 million tonnes of PFA.

This is one of the ways that we clean up the flue gases or smoke that we send up the chimney. The best thing is that, once collected, the PFA is not wasted, we sell most of it to the construction industry for use in building materials.
