Drax power station

F2

Performance

It is in the UK with an installed capacity of 3,960 MW, the largest thermal power plant and provides 7% of the total electric Energiebarfs in the UK. Maximum 36,000 tonnes of coal can be burned per day, the consumption per year is 7 to 11 million tons of coal, which has the power station Drax is the largest emitter of carbon dioxide (CO2) in the UK.

After the discovery of coal deposits near the town of Selby in 1967, these were the last new development of a coal field in the UK and one of the largest underground mining projects in the world, was started in 1973 with the planning and construction of the Drax power station. After several phases of the last of six power plant units was completed, each 660 MW in 1986.

Until the modernization turbines were in use that have been made 1973-1986 by CA Parsons and Company, a 1997 Siemens belonging to companies in service. Drax signed in 2007 a ​​contract with Siemens, which included the modernization of all the high and low pressure turbines, and the provision of a replacement set.

First, coal was used for the first completed force blocks primarily from the nearby coal fields. In the following years until today, triggered by the British miners' strike, the coal also from Australia, Colombia, Poland, Russia and South Africa is based. The transport of the ports is done by GB Railfreight.

The power plant has a total of twelve cooling towers, per production unit two.

Biomassezufeuerung

From 2016Vorlage: Future / In 2 years to 12.5 TWh per year are produced with imported Canadian wood pellets. The rightful subsidies amount to 45 pounds per megawatt hour and Drax are expected to contribute 550 million pounds a year.

After a dossier of the Economist in 2013 was by far the most successful classic wooden renewable energy sources. The beginning of a conversion of a large combustion plant made ​​in 2010 the RWE power plant in the British Tilbury, then the largest biomass power Europe, which was shut down in October 2013. Due to the technical complexity was started at Drax first to cave in wood pellets as Winner of coal, and 10% is easily possible. This co-firing allows access to substantial subsidies and reduced crediting of carbon dioxide emissions. Only because of the small amounts of wood available in the region, a large proportion of the biomass is imported from abroad.
