Sulphur dioxide (SO2)
Flue gas desulphursation (FGD) systems are used to remove sulphur dioxide. “Wet scrubbers” are the most widespread method and can be up to 99% effective.
A mixture of limestone and water is sprayed over the flue gas and this mixture reacts with the SO2 to form gypsum (a calcium sulphate), which is removed and used in the construction industry.
Typical applications for 309 and nickel base 59 Alloys
Drax Power Limited is the operating subsidiary of Drax Group plc and the owner and operator of Drax Power Station, the largest, cleanest and mostefficient coal-fired power station in the UK
The output capacity from the station’s six generators is 4,000MW. All units are fitted with flue gas desulphurisation (FGD) equipment, which removes 90% of the sulphur dioxide from emissions.
Metrode consumables are used extensively at Drax
