A gas turbine facility includes: a gas turbine; an ammonia supply device that supplies ammonia to a combustor of the gas turbine; a flow path forming frame forming an exhaust gas flow path through which exhaust gas from the gas turbine flows; a sprinkling device having a sprinkler that sprinkles water into the exhaust gas flow path; and a sprinkling controller that controls an operation of the sprinkling device. The sprinkling controller instructs the sprinkling device to start sprinkling the water on condition that an instruction to start supply of the ammonia to the combustor from the ammonia supply device or an instruction to stop the supply of the ammonia is received.

Gas turbine facility and method for suppressing discharge of ammonia from gas turbine facility

This gas turbine plant is provided with a gas turbine and a fuel supply facility. The fuel supply facility is provided with: a liquid ammonia line; a warm water line through which warm water can flow; a vaporizer which can perform the heat exchange between the warm water coming from the warm water line and liquid ammonia coming from the liquid ammonia line to heat and vaporize the liquid ammonia; a heat exchanger which can perform the heat exchange between the warm water in the warm water line and a medium; a heat exchange amount controller which can control the amount of heat exchange between the warm water and the medium to control the temperature of the warm water flowing into the vaporizer; and a gaseous ammonia line which can introduce gaseous ammonia that is ammonia vaporized by the vaporizer into the gas turbine.

Provided are an exhaust gas treatment catalyst capable of reducing ammonia leakage rate while keeping a sufficient NOremoval efficiency, said catalyst comprising a coating layer and a catalyst base material, wherein said coating layer has a decreased thickness relative to that of a catalyst base material; and an exhaust gas treatment system using the same. In the exhaust gas treatment catalyst for catalytically removing nitrogen oxides from an exhaust gas by using ammonia as a reducing agent and simultaneously decomposing and removing unreacted ammonia, a coating layer comprising platinum supported on titania is formed on a surface of a porous catalyst base material comprising titania and at least one compound selected from oxides of vanadium (V), oxides of tungsten (W) and oxides of molybdenum (Mo).

Exhaust gas treatment catalyst and exhaust gas treatment system

A catalyst for nitrogen oxide removal, which catalytically reduces nitrogen oxides in an exhaust gas in the presence of ammonia, comprises: a first component comprising an oxide of titanium, an oxide of tungsten, and an oxide of vanadium; and a second component comprising an oxide of manganese, or an oxide of manganese and an oxide of copper.

In the NHinjection rate control method for an NOremoval apparatus, operating area of the apparatus is divided into first area in which molar ratio of NHinjection rate with respect to NOflow rate at an inlet of the apparatus is smaller than molar ratio at minimum point where NOconcentration assumes minimum value and second area in which the molar ratio is equal to or larger than the minimum point molar ratio, and virtual NOconcentration with respect to the molar ratio is set according to virtual characteristic line which varies monotonically to stride across desired operating point without rising with increase of the molar ratio from the first area to the second area. Moreover, feedback control is implemented for adjusting the NHinjection rate with respect to the NOflow rate in direction that the virtual NOconcentration is brought close to the desired NOconcentration.
