Abstract
In order to suppress emission of NOx, provided is a combustion system including: a combustor to which ammonia is to be supplied; an intake flow passage connected to the combustor; an exhaust flow passage connected to the combustor ; a recirculation flow passage connecting the exhaust flow passage and the intake flow passage to each other; a denitration device provided in the exhaust flow passage; and a control device that controls a flow rate of exhaust gas circulating from the exhaust flow passage to the intake flow passage through the recirculation flow passage, based on a parameter related to an emission amount of a nitrogen oxide.

A combustion system, comprising:
- a combustor to which ammonia is to be supplied;
- an intake flow passage connected to the combustor;
- an exhaust flow passage connected to the combustor;
- a recirculation flow passage connecting the exhaust flow passage and the intake flow passage to each other;
- a denitration device provided in the exhaust flow passage;
- and
- a control device that controls a flow rate of exhaust gas circulating from the exhaust flow passage to the intake flow passage through the recirculation flow passage, based on a parameter related to an emission amount of a nitrogen oxide.
A control method for a combustion system,
- the combustion system including:
- a combustor to which ammonia is to be supplied;
- an intake flow passage connected to the combustor;
- an exhaust flow passage connected to the combustor;
- a recirculation flow passage connecting the exhaust flow passage and the intake flow passage to each other;
- and
- a denitration device provided in the exhaust flow passage,
- the control method comprising controlling, by a control device, a flow rate of exhaust gas circulating from the exhaust flow passage to the intake flow passage through the recirculation flow passage, based on a parameter related to an emission amount of a nitrogen oxide.
