ABSTRACT:
A method and apparatus for deoxidation of water uses a catalytic combustion chamber in which a fuel having a low ignition temperature is first delivered during a start-up phase in order to begin ignition. The fuel used for start-up may, for example, be vaporized methanol or hydrogen. After an interval of time, the fuel supplied is continuously throttled and, at the same time, an operational fuel having a higher ignition temperature is supplied in increasing quantities until the stripping gas reaches a required temperature. On completion of the start-up phase, only the operational fuel which consists of, or least contains natural gas as a component, is then fed to the catalytic combustion process.
