4 Large Scale Demonstration Doosan Babcock

5 Objectives Demonstration of an oxyfuel combustion system of a type and size applicable to new build & retrofit advanced supercritical oxyfuel plant To demonstrate a full-scale (40MWt) oxyfuel burner for the first time To determine burner performance with respect to NOx, combustion efficiency, flame shape, and heat transfer characteristics To determine the operational envelope of the burner with respect to flame stability, turndown, start-up, shutdown, and he transition between air and oxyfuel firing To demonstrate the safe operation of a large oxyfuel system under realistic operating conditions Ultimately To demonstrate the level of technical readiness of the oxyfuel combustion process

25 Closing Remarks

26 Closing Remarks There is significant worldwide interest in oxyfuel technology, with a number of large demonstration projects announced Large test facilities are operational or close to operation Some small utility demonstrations are at an advanced stage A number of proposed projects have been indefinitely delayed or abandoned The level of understanding has reached the point where companies are willing to invest significant sums of money in the further development of oxyfuel They are not yet ready to commit to large full-scale utility boiler plant It is only when you have to build plant and operate it that you begin to understand the practical issues!
