RWE Aberthaw Power Station in South Wales is an efficient coal fired power station, especially through the use of automation that includes Rotork valve actuation. Rotork has numerous locations throughout the Americas and globally, and its double-sealed and non-intrusive actuators are designed to withstand challenging operating environments, such as those often encountered in the power generation industry.
Following the introduction of Flue Gas Desulphurisation (FGD), which has reduced sulphur emissions by up to 95 per cent, the latest stage of Aberthaw’s multi-million pound investment for the improvement of environmental performance involves the installation of Lo NOx technology, in line with the latest Industrial Emissions Directive.
The new Lo NOx system installed on one of Aberthaw’s 535 MW (mega watt) generating sets includes 120 Rotork IQ and IQT multi-turn and part-turn intelligent electric actuators to control the operation of valves and dampers. Rotork actuators account for over 90 per cent of the site’s total quantity of valve actuation assets.
