This had been Vattenfall's larger scale demonstration project after the pilot plant at Schwarze Pumpe was opened in 2009. Janschwalde is the largest coal fired power station and the largest CO2 emitter (25 MT/Yr) in Germany. Before cancelling the project Vattenfall was in the final engineering phase for a demo plant in Jänschwalde.

This involves the simultaneous milling and drying of raw coal immediately before combustion in a beatertype mill, aerated by the hot flue gas drawn off at 900 1000°C from the upper levels of the furnace chamber. Such predrying requires a boiler substantially larger to cope with the large quantity of evaporated water.

Fig. 1 illustrates the primary components at WAC in a process flow diagram. The plant design is based on the Shell Coal Gasification Process (SCGP) in which pulverized fuel mix is converted to synthesis gas (syngas) under substoichiometric conditions in a dry feed slagging entrained flow gasifier at elevated temperatures between 1500 and 1800 °C.. The gas is subsequently cooled for cleaning ...

Introduction. Oxyfuel combustion is one of the leading technologies considered for capturing CO 2 from power plants with CCS. This involves the process of burning the fuel with nearly pure oxygen instead of air. In order to control the flame temperature, some part of the flue gas are recycled back into the furnace/boiler.
