Trends in energy sector have changed quite a lot during last years in Europe. Carbon tax, CO2 credits and government level CO2 reduction targets started low carbon fuel boom and also initiated CCS equipment development. Many European governments have created incentive system to encourage power producers to use low carbon fuels. Now the uncertainty in economy has forced governments to cut incentives and unclear situation puts many project developments on hold. Incentive system caused a price increase in low carbon fuels and customers have turned to use more demanding fuels with lower price but increase in investment cost. At the same time coal market price has stayed stabile. In this uncertain situation CFB boiler is a right solution in repowering projects – almost all the projects are replacement investments because new capacity is not needed. CFB’s biggest benefit is the capability to burn many kind of solid fuels with very different kind of characteristics - alone or in mixture. Coal qualities used in CFB are not needed to be high grade but can be high ash and/or high moisture content coals. A CFB boiler can be designed to fire 100% coal and on the other hand have a 100% biomass future provision This paper will introduce several projects started year 2014 which are proofing CFB’s superiority in repowering projects – meaning replacement investment. Projects are 30 MWe and 80 MWe cases in Czech Republic, 50 MWe case in Hungary and 30 MWe and 170 MWe cases in Finland. Paper will introduce these new projects and design features with fuel portfolio. The paper will also give same evidence that multifuel approach is not decreasing the reliability of the plant by showing operational data from existing CFB boiler operating with several fuels.
