Vattenfall - IVD ? Stuttgart

IVD Stuttgart

At the Institute of Process Engineering and Power Plant Technology (IVD) at Stuttgart University there are two test facilities in different sizes and for different purposes.

The larger 500 kW test rig in Stuttgart has a length of 7.7 meters and combusts coal, bituminous or lignite. As part of the European research project ENCAP (Enhanced Capture of CO₂), this test rig was retrofitted to allow Oxyfuel operation. It is equipped with almost all major technical equipment that power plants in operation today have and to investigate Oxyfuel conditions, a flue gas recirculation has also been installed. The combustion chamber is designed for investigations of the coal flame. In the smaller 20 kW facility coal is fired in a specified mixture of O₂ and CO₂ to simulate Oxyfuel conditions, as no recirculation of flue gases takes place. The in-going oxidiser stream can also be “contaminated” with pollutants such as SO_x, NO_x, CO and particles, in order to investigate recirculation conditions. The test rig also provides good environment to investigate staged combustion conditions. The rig is 2.5 meters long.
