Doosan Power Systems OxyCoal™ Burner Technology Development

AbstractA Doosan Power Systems 30MWth OxyCoal™ burner was designed, manufactured, installed, commissioned, tested and subsequently removed from the Oxyfuel Pilot Plant at Schwarze Pumpe, owned and operated by Vattenfall Europe Technology Research GmbH, as the next step in the development and demonstration of Doosan Power Systems OxyCoal™ technology. Various operating modes – air firing, standard oxyfuel firing and expert oxyfuel firing – were demonstrated, yielding a total time of operation close to 2800hours over the test period. The 30MWth OxyCoal™ burner was proven to have good flame stability and was able to successfully achieve the set targets of less than 3%vol. (wet) O2, 250mg/Nm3 NOx and 50mg/Nm3 CO for air firing and less than 3%vol. (wet) O2, 600mg/Nm3 NOx and 100mg/Nm3 CO for oxyfuel firing. Further measurements were taken to allow combustion and thermal performance to be evaluated. The project and the results from testing are discussed in this paper
