METHOD FOR RECOMBINING HYDROGEN AND OXYGEN IN GAS MEDIUM AND HYDROGEN-AND-OXYGEN RECOMBINER Russian patent published in 2005 - IPC

FIELD: nuclear power engineering, transport, chemical mechanical engineering, and other industries.

SUBSTANCE: proposed method for recombining hydrogen and oxygen in gas medium meant to ensure hydrogen safety includes bringing of gas mixture in contact with heated catalyst body disposed along heat-conducting channel to ensure heat transfer between them. Temperature of heat-conducting channel hot end at point of its contact with catalyst body is maintained between 150 and 350 °C and temperature of its cold end at point of its contact with catalyst body is maintained below that of hot end. Gas mixture is passed through catalyst body from cold end of heat-conducting channel to its hot end. Hydrogen-and-oxygen recombiner has case with inlet and outlet sections, as well as heat-conducting channel disposed in-between and catalyst body placed on the path of gas mixture flow along heat-conducting channel. The latter is equipped on conducting end with cooling device and on outlet end, with heater. Hydrogen concentration working range is extended to 0.5 - 25% of gas mixture.

EFFECT: enlarged hydrogen concentration range, enhanced operating reliability under different operating conditions.
