A combustion device includes an ammonia supply unit supplying primary reduction ammonia as a nitrogen oxide reducing agent into a combustor and mixing secondary reduction ammonia with combustion exhaust gas discharged from the combustor to reduce nitrogen oxide contained in the combustion exhaust gas and a controller configured to control at least one of the amount of supply of the primary reduction ammonia and the amount of mixing of the secondary reduction ammonia with the combustion exhaust gas in accordance with concentrations of residual nitrogen oxide and residual ammonia contained in the combustion exhaust gas after being discharged from the combustor.

Combustion device and gas turbine

A combustion device burns fuel ammonia with combustion air in a combustion chamber, and includes: a combustor liner which forms the combustion chamber; a burner which is installed at one end of the combustor liner; a deflection member which is provided on a downstream side of the combustor liner in a flow direction of a combustion gas, and is configured to deflect the flow direction of the combustion gas; and at least one ammonia injection hole which is provided between the burner and an outlet of the deflection member and is configured to supply the fuel ammonia into the combustion chamber.

The heat cycle facility includes: a first vaporizer that vaporizes a first liquid heating medium by combusting fuel; a first motive power generator that generates motive power by using as a drive fluid a first gas heating medium obtained at the first vaporizer; a condenser that condenses the first gas heating medium discharged from the first motive power generator by heat-exchanging the first gas heating medium for a second liquid heating medium; a circulator that pressurizes the first liquid heating medium obtained at the condenser and supplies the pressurized first liquid heating medium to the first vaporizer; a second vaporizer that produces gaseous ammonia by heat-exchanging the second liquid heating medium for liquid ammonia; and a supplier that supplies the liquid ammonia to the second vaporizer.

Heat cycle facility

The combustion device includes: a compressor that compresses combustion air; a combustor that combusts the compressed combustion air and fuel ammonia; and an ammonia injector that injects the fuel ammonia into the combustion air during or before compression of the combustion air by the compressor and cools the combustion air.

Combustion device and gas turbine engine system

A combustion device burns fuel ammonia in a combustion chamber using compressed combustion air, and includes a combustion air cooling unit which is configured to cool the combustion air by heat exchange with the fuel ammonia during or before a compression process.

A gas turbine denitrifies combustion gas by using a denitrification catalyst and ammonia as a reducing agent, the gas turbine includes: a turbine provided with turbine blades, the turbine blades being exposed to the combustion gas reaching a temperature higher than an average value in a temperature distribution of the combustion gas, and a compressor configured to supply the turbine blades with a cooling air and the ammonia, wherein the gas turbine is configured to lower the temperature of the turbine blades by supplying the turbine blades with the ammonia and the cooling air.

Gas turbine

A combustion device burns fuel ammonia in a combustor using combustion air, and includes a catalyst reduction unit which is configured to reduce nitrogen oxides in a combustion exhaust gas supplied from the combustor, in which at least a part of the fuel ammonia is supplied to the catalyst reduction unit as a reducing agent for the nitrogen oxides in the combustion exhaust gas.

The combustion device includes: a combustion chamber in which fuel is combusted using combustion air; and a reducing agent injector that injects a reducing agent toward flames in the combustion chamber.

In an information distributing method, an information providing resource receives from an information user unit a request statement including a code to identify first information and information (URI) to identify second information quoted in the first information. According to the identifying information of the second information included in the request statement, the information providing resource determines whether or not transmission of the second information to an information providing unit is allowed. The information providing side can control the operation in which the second information thereof is quoted to be opened in the first information.
