燃焼が行なわれる。 For example, in an integrated steelworks, blast furnace gas generated from a blast furnace (hereinafter referred to as B gas), coke oven gas generated from a coke oven (hereinafter referred to as C gas), converter gas generated from a converter, etc. By-product gases are generated, and these by-product gases are used as heat sources for boilers and other heat equipment depending on the purpose, in order to make effective use of them. For example, in a boiler that generates a large amount of steam, B gas is used as the main fuel and C gas is used as the auxiliary fuel, and the combustion thereof is controlled as shown in FIG. That is, B gas 1 and C gas 10 are supplied to boiler combustion chamber 7 via piping 1a and 10a, respectively. The theoretical air amount is determined from the calorific value of these fuels, and if a constant air ratio is determined by the B gas ratio adjuster 6 and the C gas ratio adjuster 14, the amount of air for combustion is determined, and the amount of B gas, Even if the amount of C gas changes, the change is detected by the gas flow meters 3 and 12, and the respective air control valves 5 and 16 are adjusted accordingly, so the amount of combustion air follows and the combustion air 2 , 11 are supplied through the respective pipes 2a, 11a, and are burned in the respective burners 8, 15 in the combustion chamber 7. The oxygen concentration in the exhaust gas is measured by an oxygen meter 9, and combustion is performed at a constant concentration.

酸素濃度を上げる）する方法がある。 Furthermore, due to the supply and demand balance of oxygen within the steelworks, there is often a surplus of oxygen. One way to effectively utilize this oxygen gas is to enrich the combustion air of a boiler with oxygen (mix air and oxygen to increase the oxygen concentration in the combustion air).

きない。 However, when pure oxygen is mixed into the combustion air to increase the oxygen concentration in the combustion air to increase combustion efficiency, combustion cannot be controlled as described above. In other words, when the oxygen flow rate and fuel flow rate during enrichment change, even if the fuel calorific value is constant, the combustion air is determined by giving a certain fixed air ratio to the theoretical air amount calculated from this. Combustion cannot be carried out with this combustion air.

It is burned at a fixed air ratio. In the case of normal combustion in which B gas 1 is simply blown in with combustion air, the combustion gas flow rate signal from the B gas flow meter 3 is input to the calculator 20, and the calculator 20 performs the same operation as the air comparator. The theoretical air amount is determined from the calorific value of the B gas 1, and the air 2 necessary for combustion is adjusted by the air control valve 5, and combustion is performed with the amount of combustion air according to the B gas flow rate.

On the other hand, the amount of combustion air required for 1Nm 3 of B gas (see Fig. 3) for the oxygen concentration of enriched air is input in advance into the calculator 20 so as to obtain the optimum air-fuel ratio. The subsequent oxygen concentration in the enriched air is detected by the oxygen analyzer 18, and this oxygen concentration signal is input to the calculator 20. For example, when the oxygen concentration of enriched air is 30%, in order to keep the oxygen concentration in the exhaust gas detected by the exhaust gas oxygen analyzer 9 constant at 1.5%, 1Nm 3 of B gas is required as shown in Figure 3. The amount of combustion air is 0.47Nm 3 , and the B gas combustion air adjustment valve 5 is adjusted so that this amount of combustion air flows.
