Abstract: Since June 1999, work has been continued on behalf of the OMV AG Vienna for a consistent development of Low- NOx-concepts for the combustible fuel oil light also for higher burner outputs. Together with the MAX WEISHAUPT GmbH, a leading company in fuel engineering, the OMV AG has therefore initiated a project, the aim of which is the development of a Low- NOx-mixing device in the capacity range 500 kW-3 MW. The aim of this project, carried out at the Oel-Warme-Institut (OWI) in Aachen, is to allow also for the recently developed burner, beside minimal CO and soot emissions (CO < 20 mg/m³ RZ < 1), a NOx-emission below 400 mg/m³. With a design capacity of 500 kW and 1.2 MW, the construction sizes I and II of the new development project for the moment are on the test stand - the measured NOx-emissions show that a high NOx-reduction potential exists and the corresponding project aims can be fulfilled. By means of several CFD investigations of the present combustion system with the software code CFX the phenomena, important for the practice, could be verified and the understanding of these phenomena substantially be improved.
