ABB actuators will slash maintenance requirements at Longannet.

The article informs about Scottish Power PLC's purchase of electric actuators worth £300,000 from ABB Ltd. for its Longannet power plant. The Longannet power plant is the largest power plant of Europe and second largest coal-fired power station in Great Britain. The plant produces 600MW of electricity, serving the need of two million people. Eight pulverized mills are used to fulfill the coal demand of Longannet's four generating units. Dampers are installed to control the combustion produced from mills. Around 56 part-turn actuators are designed to control the mill dampers which are sufficient for three to four production units. Other actuators from ABB Ltd. regulate valves to control the flow of water entering into the boiler.
