FIELD: chemical technology processes with use of catalyst carrier. SUBSTANCE: apparatus for recombination of hydrogen and oxygen with the aid of catalyst carrier has the catalyst carrier in a jacket, having at least one inlet opening and at least one outlet opening, tightly sealed by first gates, being opened in dependance upon temperature until these gate operation temperature is over. A gas permeable filter is mounted in the jacket in such a way, that after the first gates had been opened, gases or gas mixtures, being fed into the inlet opening, may achieve the catalyst carrier only by passing through the filter. The filter is impermeable for aerosols and fats. The jacket has at least one additional opening, tightly sealed with the aid of the second gate, being opened in dependance upon temperature until this gate operation temperature is over. The operation temperature of the second gate is more, than operation temperature of the first gate. The second opening is arranged in the jacket in such a way that the catalyst carrier is subjected to action of atmosphere outside of the jacket without intermediate using of filters. EFFECT: enhanced efficiency. 16 cl, 3 dwg
