FIELD: control and intensification of flame burning. SUBSTANCE: intensification of flame burning is obtained due to treatment of flame by strong longitudinal electric field (2 kV/cm and higher) and revolving strong transverse electric field, for example, by means of three-phase system of electrodes and three-phase high-voltage source. Method also includes measurement of flame height and other parameters, change in inter-electrode distance of application of longitudinal field to flame at simultaneous adjustment of field intensity. Method also provides for rotation of flame by transverse electric field, thus enhancing degree of mixing and crushing of fuel-air mixture and intensifying combustion additionally. Proposed new procedure of atomizing the fuel into combustion zone by longitudinal electric field to molecular level intensifies additionally burning procedure, thus reducing the consumption of fuel. The proposed method makes it possible to control geometry of flame, its temperature and heat conductivity; to effect focusing of flame through change in its geometry and in electrical parameters of above-mentioned fields, which is absolutely necessary for heat treatment of metals and alloys. EFFECT: enhanced controllability and intensification of combustion at improved ecological cleanness; increase of intensity of combustion by 40 to 50 percent; reduction of consumption of oxidizer by 30 to 40 percent; reduction of toxicity of waste gases by 30 to 80 percent (by separate components). |
