Combustion system |
| abstract |
Provided is a combustion system that is capable of removing nitrogen oxides exceeding a regulation value while keeping the amount of ammonia slip level at or below a prescribed value, even when a denitration catalyst used in a denitration apparatus degrades. A combustion system 1 comprises: a first denitration apparatus 30 for removing nitrogen oxides from exhaust gas expelled from a boiler 10; and a second denitration apparatus 70, positioned downstream of an air preheater 40, for removing nitrogen oxides from exhaust gas expelled from the air preheater 40. The first denitration apparatus 30 controls ammonia dosage on the basis of the amount of ammonia slip. The second denitration apparatus 70 controls ammonia dosage on the basis of outlet nitrogen oxide concentration. |
