2 The Danish Fuel history 50ties Lignite and Peat (lower grades of coal) Oil 60ties 70ties 80ties 90ties Lignite to Oil and Coal (higher energy content than Lignite) Late 60ties oil exploration in the North Sea 1972 oil produced 1973 and 1979 World Oil crises 75% of Power based on Oil Danish Government started focusing on higher efficieny 1984 Natural Gas production starts in the North Sea Conversion of plants to Natural Gas and Oil Development of USC concept 1984 Government want SOx reduction by Burning straw on the fields banned by DK Government 1992 CO2 penalty result in High efficiency Hybrid Coal plants

3 The Danish Fuel history % of power production on natural gas in Danish Government release Climate Strategy Implementation of Renewable energy (Wind Biomass) 2010 Conversion of fossil Power Plants into Biomass Off shore windmill parks in large scale 2020 The future By 2020 Renewable to cover 50% of power production By 2050 fossil free

4 History Company founded in 1843 First steam boiler supplied in 1852 First Benson once-through boiler in 1960 (Siemens license) Ownership Part of Lentjes in 1980 Part of Deutsche Babcock in 1991 Part of FLS Miljø in 1997 Part of the Italian STF S.p.A. in 2002 BWE India founded in 2009 Burmeister & Wain Energy A/S Lundtoftegårdsvej 93A DK-2800 Kgs.

5 Denmark in the World Elite Three World Records held by BWE: over 47% in efficiency on a coal fired power plant, commissioned in 1998 Largest USC Hybrid Multi Fuel boiler using biomass and fossil fuels, commissioned in 2001 The first 100% straw and wood pellet fired SC boiler over 300 MW, commissioned in 2009 Burmeister & Wain Energy A/S Lundtoftegårdsvej 93A DK-2800 Kgs.

6 Efficiency Development on Danish Power Plants Net Efficiency (LHV) Denmark Europe China USA World % Ensted MW Esbjerg 3 Avedøre 2 Fynsv. 7 Studstrup 3/4 Line of Super Alloys Line of Steel No rdjylla ndsværket World USA China Europe Denmark 14 years of operational experience Commissioning Year (Avarage efficiency)

7 Why is efficiency so important The effect of an efficiency increase of a coal fired power plant from 30 to 47% is: CO 2 emission reduced by 33% Coal consumption reduced from 480 to 320 g/kwhe If Russia use 80 mill tons of coal per year, an efficiency increase could save 25 mill tons of coal per year

9 BWE s Biomass Uniqueness Biomass boiler and combustion technology PF biomass boilers capacity range MWe (100% backup on gas, oil or coal) Smaller scale (25 to 150 MWth) grate fired power plants for straw bales and wood chips HP1.3 HP1.2 RH2 HP1.1 RH1.2 HP2 Screen RH1.1 OFA OFA ECO2 OFA ECO1 4 x 3 burners 3 mills APH ESP desox denox PA fans FD

10 BWE s unique retrofit technology Optimization of existing boilers for lower CO 2 emission Higher efficiency Retrofitting of existing boilers for implementation of the Hybrid Multi Fuel BWE technology Retrofitting of Herningværket (1982), DONG Energy, Denmark 1982 Coal/Oil 2000 Gas/Oil 2002 Bio/Gas/Oil 2009 Wood pellet dust firing

11 BAT conclusions Efficiency wood pellet 40-45% (565 dgr.c, PF firing) Efficiency straw bales 33-35% (540 dgr.c, grate firing) Multi fuel concept burning 100% wood pellets, 100% natural gas,100% coal and 100% oil in one boiler Proven technology USC bar, dgr.c USC Efficiency hard coal (bituminous) % USC Load range hard coal % USC Load change rate hard coal 5%/min USC CHP fuel efficiency 94% NOx hard coal low NOx burners + SCR: mg/nm3 (6% O2, dry)

12 What to obtain - Efficient hybrid power production - Use of local biomass - Potential local earnings Build new plants (small or large) using BWE hybridor biomass-concept using proven technology Retrofit and upgrade old plants by using BAT Use the multi fuel concept in new builds and retrofits (Same boiler can use coal, gas, oil and biomass)
