Abstract
An apparatus for catalytically combining hydrogen and oxygen which includes two concentric catalyst chambers arranged so that the outer chamber surrounds the inner chamber and the gas stream passes radially through the outer catalyst chamber.
Claims10
An apparatus for recombining oxygen and hydrogen comprising:
- a long, centrally disposed, tubular passageway;
- an initial catalyst chamber within the passageway containing a catalyst capable of recombining oxygen and hydrogen;
- means for delivering a gas stream containing hydrogen and oxygen to the tubular passageway;
- a generally annular final catalyst chamber containing a catalyst capable of recombining oxygen and hydrogen, the final catalyst chamber extending over a significantly greater length than the initial catalyst chamber and surrounding the tubular passageway in a spaced apart relationship therewith so that a gas flow channel is formed between the tubular passageway and final catalyst chamber;
- means for removing the gas stream from the tubular passageway after the gas stream has passed through the initial catalyst chamber and for delivering the gas stream to one of the long sides of the final catalyst chamber so that the gas stream flows radially through the final catalyst chamber in a direction generally perpendicular to the direction of flow of the gas stream through the initial catalyst chamber;
- and outlet means for removing the gas stream from the apparatus after it has passed radially through the final catalyst chamber.

An apparatus for combining oxygen and hydrogen comprising:
- a housing;
- a means for delivering a gas stream containing oxygen and hydrogen to one end of the housing;
- a long, axially disposed, tubular passageway within the housing which extends from the end of the housing to which the gas stream is delivered, said passageway being in flow communication with the gas delivery means;
- a relatively thick, packed bed, initial catalyst chamber disposed within the tubular passageway so that the gas stream flows axially through the catalyst chamber as it flows through the passageway;
- a generally annular final catalyst chamber within the housing which surrounds the initial catalyst chamber and the tubular passageway and is spaced apart from the tubular passageway to form a channel between it and the tubular passageway and which has a long, relatively thin, packed bed extending over a significantly greater axial length than the initial catalyst chamber;
- a means within the housing, in flow communication with the tubular passageway, for delivering the partially recombined gas stream to the channel so that the gas stream will flow radially outward through the thin packed bed of the final catalyst chamber;
- and, outlet means, in flow communication with the outer side of the final catalyst chamber, for removing the gas stream from the apparatus after it has passed radially through the final catalyst chamber.

- and, outlet means, in flow communication with the channel, for removing the gas stream from the channel and the apparatus.
