The purpose of the pilot plant is to validate engineering work, to learn and better understand the dynamics of oxyfuel combustion and to demonstrate the capture technology

Operation of the Oxyfuel Pilot Plant (OxPP) will

– Build up confidence in oxyfuel technology

– Reduce the risks involved in the industrial utilisation

– Prove the operability of the whole process chain from coal handling to CO2 delivery

The Oxyfuel Pilot Plant (OxPP) project aims to jointly develop oxyfuel combustion technology suitable for commercially viable application in future large-scale power plants.


17


Doosan Power Systems has joined the Technology Partnership for the Oxyfuel Pilot Plant (OxPP) project

– Agreement signed between Vattenfall Europe Technology Research GmbH and Doosan Power Systems in December 2010

Doosan Power Systems is responsible for providing an alternative burner (30MWth OxyCoal™ burner) for testing on the 30MWth pilot plant in Schwarze Pumpe, Germany.

The Oxyfuel Pilot Plant (OxPP) tests intend to improve the oxyfuel combustion process as well as establish a better understanding of the behaviour of individual components within the process chain.


18

Schwarze Pumpe Vattenfall Oxyfuel Technology Sharing Group Doosan Power Systems OxyCoal™ burner design is based on our existing knowledge, experience and expertise of low NOX air-fired burner technology.

Operational tests will determine the global performance of 30MWth OxyCoal™ burner and Oxyfuel Pilot Plant (OxPP).

Comparison and analysis of results over a range of conditions will identify clear, definitive trends of burner operating behaviour.

Fundamental tests will allow detailed mapping of the combustion conditions at well defined operating points.

Evaluation will provide greater understanding of the combustion operation at discrete points and the underlying mechanisms responsible.
