Improving electrostatic precipitator performance for power stations

Although no new coal-fired power plants have been built in the UK for a number of years, those remaining in service have had their precipitation plant, for controlling fly ash emissions, cost-effectively upgraded, both in terms of performance and reliability, such that they comply with existing environmental regulations. This upgrading, together with possible future measures, is reviewed and there is no reason why many of the existing operating plants should not meet proposed EU directives for a number of years to come.
