FIELD: chemical processes. SUBSTANCE: aim is to provide initiating and running of radiation-chemical reactions in gasses mediums and steam-gasses mediums during metallurgical and chemical works gasses exhaust purification. Aim is realized due to the fact, that electronic emission is introduced in reaction chamber, inside which there is permanent magnetic field, direction of which is transversal to electrons trajectory. Charged particle movement in operational medium is accompanying with energy losses for ionization and excitement of atoms. Trajectory of ELECTRONS flying in chamber tangentially to initial Larmor circumference is rolled up in spiral. Method and apparatus allow to provide full absorption of emission energy in operational medium and uniform doses of absorption along whole cross-section of radiation chamber. EFFECT: emission energy full absorption in operational medium, uniform doses of absorption along radiation chamber cross-section. 3 cl, 3 dwg
