Abstract

A process for producing an inert or reducing atmosphere containing nitrogen from ammonia gas and combustion fumes of a hydrocarbon, characterized in that it comprises at least the following steps: a) hydrocarbons are burned with air, example with 1 to 3% excess air or without excess air; b) ammonia gas is decomposed by heat, using a part of the heat produced by stage (a); c) the gases produced by steps (a) and (b) are mixed and the oxygen is removed by combining, in the presence of a catalyst, with a part of the hydrogen contained in these gases.
