In the combustion of gaseous fuels containing inert gas, the pure oxygen feed is increased and the air feed is reduced to compensate for the variations in the proportions of inert gas in the fuel gas during operation, the pure oxygen feed being reduced if the amount of inert gas in the fuel gas rises and the air feed being increased if the amount of inert gas in the fuel gas decreases. In particular, the amount of ballast gas, that is to say the sum of the amount of inert gas in the fuel gas and the amount of nitrogen in the combustion air, is kept constant. The control can be carried out by means of the ratio of the amount of flue gas to the amount of combustible components in the fuel gas. The method can be used, in particular, in the Claus process. <IMAGE> |
