Abstract
The water is brought into contact with a gas mixture for the removal of its oxygen content. The gas mixture is then circulated in a circulation (6, 7) and at the same time the oxygen is removed from the gas mixture charged therewith in a catalytic device (9) by means of a fuel gas. For this purpose a gas mixture (15) is produced from a fuel gas (12) and an inert gas (13), conveyed to the circulation in an explosion-proof manner and added to the recycling gas by mixing. The fuel gas content and the inert gas content of the gas mixture supplied (15) are adjusted so that the resultant gas mixture (16) in the circulation in front of the catalyst device (9) has firstly an excess factor E=1 and so that secondly it lies under the ignition limit (Z). This produces by simple means a cost-effective plant, which can be operated so that it is explosion-proof.
