FIELD: hydrogen recombination at nuclear power plants. SUBSTANCE: device designed in particular to prevent unwanted ignition of gas mixture has catalyzing system disposed in casing made leaky for free convection of gas mixture. Attached to this system is respective flame holding device. The best alternative is building the latter into precipitation trap so as to reliably prevent escape of hot catalyst particles from catalyzing system in opposition to gas mixture flow. EFFECT: provision for flameless operation of recombination device. 20 cl, 4 dwg
