Petcoke at Drax Power Station By Ian Wright Houston
Introduction to Drax Power Station • Drax Power Station is the largest, cleanest and most efficient coal fired power station in Western Europe • The generating capacity of the station is 4,000MW. It provides approx. 7% of the UK’s electricity needs. • Drax currently burns 10mt coal per year. This is made up of 50% indigenous coal and 50% imported coal (including petcoke). • Flue Gas Desulphurisation fitted on all Units. • We have the lowest emissions per MW of all UK Coal Fired Power Stations.
History of Drax • Built in two phases : Three Units Commissioned in the mid 70’s and the other three Units Commissioned in the mid 80’s • Government owned up to 1990 • Privatised in 1990 – owned by National Power • AES took over in 1999 • Became an Independent Utility in 2003 • Now a listed company on the London Stock Exchange: Drax Group plc
Drax and the UK EA Constraints • We operate to UK and EU Laws on emissions and our government are committed to Kyoto protocol on CO2 reduction. • We are restricted on SOx, NOx, CO2, particulates, metal emissions, to air , water and land. • In 2008 the Large Combustion Plant Directive (LCPD) was implemented – tighter emission limits on NOx and SOx

Alternative Fuels • Plan is to burn up to 15% of Biomass by 2010 • Wood Pellets • Sunflower Pellets • Authorised to burn up to 600kt of Petcoke • 2007 consumption - 140kt • 2008 consumption - approx 280kt • 2009 consumption - 400kt ?
Petcoke • Fully authorised to burn Petcoke commercially across all Units up to 600kt per year. • The throughput will be dependant on the price relative to Coal. • Looking for a locked in price differential against API 2. • Petcoke: • Up to 7% sulphur • Vanadium less than 1250ppm • Nickel less than 270ppm
Additional Costs when burning Petcoke ? • Shipping Costs • Smaller vessels • Lower Bulk Density material • UK Transport Costs • Less tonnage per train • Higher Sulphur Material • Increase in FGD costs • Works power • Limestone • Gypsum Handling • Uses up potential saleable sulphur credits • Ash Quality • Higher Carbon In Ash • Lower revenue • Emissions‘ • Higher Sulphur • NOx ?
Value of Petcoke to Drax • Commercial advantage over Coal • Balances against low sulphur Russian Coals • High CV Compliments Biomass Burn
