An apparatus, consisting of a Seitan 20 gas burner with a fuel flow rate 20 m3N/h, supplied with a system of Kanthal electrodes and an adjustable source of a high voltage, was investigated on the experi- mental bench of Bucharest Metallurgic Research Institute, ROMANIA. It was found that an increase of volt- age up to 12 kV, and current up to 32 μA, respectively, results in the evident improvement of the burning process: increasing of flame temperature from 1100 up to 1190oC, decreasing of CO percentage from 1.2 up to 0.012%, reducing of the fuel consumption about 5%. Annual savings resulted from the using of such appa- ratus is around 292 USD. A new technology of nitrogen and sulphur oxides removal in the installations for burning of organic fuels, which is based on the oxidation of the last ones up to the corresponding acids used pulsed corona discharge and alternating electric field, neutralization of the formed acids by introduction of ammonia in gas and receiving of nitrate and sulphate of ammonia used as fertilizers, is proposed.
