Abstract
In a catalytic recombiner system a stoichiometric mixture of oxygen and hydrogen are carried by a nitrogen stream through a catalytic converter. The stoichiometric mix is maintained by introducing oxygen into the stream under control of logic circuitry. The logic circuitry responds to the hydrogen level in an inlet stream and to oxygen levels before and after the catalytic converter.
Claims10
In a recombiner system in which first and second components of a gas mixture are combined in a reactor, the improvement comprising:
- a first component gas analyzer for providing an indication of the amount of said first component in an inlet gas stream upstream from the reactor;
- a gas flow passage from the first component gas analyzer to a downstream mixing point where an amount of said second component is introduced into the gas stream, the gas flow passage providing a delay time T for the gas stream;
- electronic control circuitry responsive to the first component indication to provide a second component signal indicative of the amount of said second component which must be introduced into the gas stream to provide a predetermined ratio of the first and second components;
- and
- second component flow rate control means responsive to the second component control signal for introducing a second component gas flow into the gas stream at the mixing point, the time required to change the second component flow in response to a change in the first component at the gas analyzer closely matching the delay time T.
