Abstract: 1,013,015. Agitating by magnetic and electric fields. A. B. KJELLSTROM. Aug. 16, 1962, No. 31533/62. Heading B1C. [Also in Divisions F4 and H2] In a combustion process greater relative movement between the fuel and air is obtained by subjecting the charged particles to the action of electric and/or magnetic fields which oscillate with at least two different frequencies. As shown, region Q is the combustion zone and the gases within duct 1 are agitated by an electric field produced by electrodes 2, 3 and a magnetic field produced by coil 10 thereby intensifying the combustion process. The hot combustion products then pass through an energy conversion region P where they interact with magnetic fields A-E to generate power between the pairs of electrodes and finally to a heat exchanger (boiler) region R where the gases are again agitated by the field associated with electrodes 4, 5 to improve the heat-exchanger efficiency. Alternating fields having frequencies within the range of I c/s to 5 Mc/s, preferably as a multiple of the supply frequency, are stated to be used.
