1 1 Project KVV 8 in Värtan

2 KVV8 production capacity CHP plant KVV8 built robust and fuelflexible with CFB technology (biofuels like grot, bark, wood chips, etc. and coal is possible reserve fuel). 330 MW thermal boiler capacity at 140 bar and 560 C. Electric power capacity gross, 130 MW. District Heating capacity, 280 MW including 80 MW of fluegascondensing with humidifier. 2

4 Important steps towards sustainable energy locally and globally Reduces CO2 emissions locally by about tonnes per year Reduces CO2 emissions globally about tonnes per year

5 Fuel supply Stable and competitive fuel prices obtained through access to various fuel markets locally - regional - global. Several independent logistics necessary to secure a safe supply of fuel. 5

8 Fuel conveyor tunnel Tunnel is sectioned for fuels, ash, service trucks and escape route. Location is reserved for a conveyor with pellets as a future possibility 8

9 Fuel crane unloading equipment for chips For KVV8 required approximately m3 of wood per day. 1 trains per day (About 3000 m3) Maximum Capacity Ships> 100% The pier is 200 m long. Maximum shipsize m3, with larger cranes. 9

10 Bränslehantering Lagring av bränsle Bränslelager, två stackar med ca m3 i varje stack. Damask för att minska damning vid högt fall av bränsle. Inkommande bränsle lastas in med vandrande bandtransportör i taket. En linje på 3000 m3/h Två skruvutmatare per stack, totalt fyra skruvar. Möjlighet att mixa bränsle i olika kapaciteter från stackarna. Varje skruv har kapacitet ( m3/h). D.Nilsson

11 Bränslehantering Matning till panna Elevatorschakt i slutet av panntunnel, bottennivå -17 m. Två fliselevatorer för full redundans (1050 m3/h /styck), körs växelvis med byte en gång/månad. En kolelevator för reservbränsle om flislagret är tomt (120 m3/h) Leveransgräns mot panna går vid utmatningsstup från fliselevatorer vid ett brandspjäll. Mindre schakt i norra delen av pannhuset för flygaska och förbränningsluft från lager. Extra bandmagnet ovan flistransportör för att hindra magnetisk material i elevatorer D.Nilsson
