Abstract
Electric field control of combustion offers the potential of stabilizing flames and reducing emissions with comparatively little effort. The concentration of pollutants such as CO, NO, and NO2 in the presence of an electric field depends on the ratio U/p of electrode voltage U and pressure p, which implies that the electric field strength required to obtain a given effect increases linearly with pressure. In an electric field directed towards the burner, CO emissions could be reduced by about 90%, irrespective of pressure. The decrease of CO was accompanied by an increase of NOx by about 20%. The electric power required for a CO reduction of 90% amounted to 0.1% of the thermal power. The improvement of the lean blow-off limit upon application of an electric field observed so far ranged from 1 to 3 % and increases with pressure. Experiments were conducted in the high-pressure burner facility at the Department of Technical Thermodynamics of the University of Erlangen. The combustion chamber with 200 mm ID and 420 mm height was designed and constructed for flame experiments in the pressure range from 1 to 11 bar. Premixed methane and air exited the burner head through a central hole 9 mm dia which is surrounded by six further hole 7 mm dia such that 7 flames coexist on the burner. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
