One of the most suitable forms of arrestment device for meeting these levels of emission, particularly for process plants producing large gas flow rates, is the electrostatic precipitator. Following the installation of the first pulverised coal steam raising plant in the 1920s, where some 90 per cent of the ash can be carried forward with the waste gases, the electrostatic precipitator has been almost universally used to control particulate emissions in the power generation industry.
