Drax Group station in the UK. In 1988, Drax became the first power station to invest in the retrofit of flue-gas desulfurization (FGD) equipment, making Drax the cleanest coal-fired power station in the UK. This removes at least 90 per cent of the sulfur dioxide (SO2) from emissions. Through retrofitting boosted-over-fire-air (BOFA) technology on all the boilers emissions of oxides of nitrogen (NOX) are being further reduced. At the same time, by-products of the coal combustion and FGD processes are recycled through their further use in the construction industry. In 2012, Drax power station completed a five-year £100 million project – the
Drax power station scheduled begin in late 2010 and to take up to three and a half years. Two other 300 MW biomass plants were planned by Drax at the ports of Hull and Immingham. In 2012 Drax group abandoned plans for the discrete biomass plant development, due to changes in government subsidies for biomass energy production favouring plant conversions over newly built plants. It switched to a project to convert half of the units at its existing plant to biomass firing. In September 2012 Drax Group announced the conversion to full firing with biomass of three of its six units. The first
