摘要： A reducing agent such as ammonia, urea or hydrazine effecting selective reduction reaction with an exhaust gas from a gas turbine is injected into a duct of the turbine along with water, and at the same time compressed air from a compressor for the turbine is jetted in the duct to atomize the reducing agent. An amount of the water is controlled so that the surrounding temperature will be suitable for reduction of nitrogen oxides of the exhaust gas. The atomized reducing agent flowing in the duct is decelerated by silencers disposed in the duct, especially by a particular arrangement thereof, so that the reducing agent will be in good contact with the exhaust gas to sufficiently reduce the nitrogen oxides. Catalyst layers are used according to kinds of the reducing agent. The catalyst layers are disposed in the silencers or at the positions that the silencers are disposed.

摘要： A method of starting a gas turbine plant, which plant has at least one combustor including a primary combustion chamber into which primary fuel nozzles open and a secondary combustion chamber into which secondary fuel nozzles open, a compressor for supplying the combustor with compressed combustion air, and a gas turbine driven by the combustion gas generated in the combustor and adapted to drive a load such as an electric power generator. When the gas turbine is being accelerated to a rated speed or while the load is still below a normal load range, a fuel is supplied only to the primary fuel nozzle, whereas, in other loaded operation range, the fuel is supplied to both the primary and secondary fuel nozzles. Before the fuel supply to the secondary fuel nozzles is commenced, a part of the compressed air is bled through at least one air bleed pipe leading from the compressor and having an air bleed valve. The air bleed valve is controlled in such a manner that the opening degree thereof is maximized when the fuel supply to the secondary fuel nozzles is commenced and is progressively decreased in accordance with the increase of the load such as to become substantially zero when the load has been increased to the normal load range.

摘要： A hot gas containing nitrogen oxides is admixed with ammonia and hydrogen peroxide to reduce the nitrogen oxides to nitrogen and water. Reduction reaction of the nitrogen oxides by ammonia is considerably promoted in a temperature range of 400.degree. to 800.degree. C. by the addition of hydrogen peroxide, and also ammonia present in excess of the nitrogen oxides is decomposed thereby, eliminating an unreacted ammonia effluent.

摘要： A power generating plant which includes a direct contact-type heat exchanger. A low-boiling point medium such as freon and a heat-source medium such as heated oil, are injected from a lower portion of the heat exchanger so that the two media are brought into direct contact with each other thereby vaporizing the gaseous low-boiling point medium. The low-boiling medium acts as a working fluid while it circulates through a closed cycle of the plant which includes a turbine and a condenser. The heat-source medium, circulates in a closed cycle of the plant which includes a heating unit.

摘要： Part of high-pressure air is extracted from the vicinity of the final stage of a compressor and is introduced into a water spraying chamber, and water at the normal temperature is injected into the high-pressure air from a nozzle installed in the water spraying chamber, to prepare a cooled coolant. The coolant sometimes contains water drops. The cooled coolant is fed into coolant passageways which are provided inside a moving blade in a manner to extend from the root part to the tip of the moving blade. When the coolant passes through the passageways, the moving blade is cooled by the coolant, and after the cooling, the coolant is emitted into a turbine main gas passageway. In case where the water drops are contained in the coolant, they vaporize during the cooling of the moving blade, to cool the air of the coolant, to suppress the temperature rise of the coolant and to enhance the cooling effect.
