本発明は吸気に水を噴霧する圧縮機を有する設備、およびその運転方法に関わる。 The present invention relates to equipment having a compressor for spraying water into intake air, and an operation method thereof.
特開平１０−２４６１２７号公報や国際公開第９８／４８１５９号パンフレットには、圧縮機吸気に水噴霧して吸気温度を外気温より低下させ、さらに高湿分空気とすることにより、ガスタービンの出力と熱効率を向上するガスタービンシステムが開示されている。 In Japanese Patent Application Laid-Open No. 10-246127 and WO98 / 48159, the output of the gas turbine is obtained by spraying water on the compressor intake air to lower the intake air temperature from the outside air temperature and further to make the air high humidity. And a gas turbine system for improving thermal efficiency is disclosed.
圧縮機吸気に水噴霧するガスタービンシステムでは、冬期のように外気温度が低下して凍結のため水噴霧ができない場合には、圧縮機に供給される空気の湿分が低下し、圧縮機で圧縮された空気温度が上昇する。数ＭＷ規模の設備では、圧縮機の圧縮比がさほど大きくないため、水噴霧したときと比較して水噴霧しないときの圧縮後の空気温度上昇は、外気温度低下と相殺する程度であり、タービン冷却のために圧縮機から抽気する空気温度は、タービン冷却上、特に問題となっていなかった。 In a gas turbine system that sprays water on the compressor intake air, when the outside air temperature drops and water spray cannot be performed due to freezing as in winter, the humidity of the air supplied to the compressor decreases, The compressed air temperature rises. In equipment of several MW scale, since the compression ratio of the compressor is not so large, an increase in air temperature after compression when water is not sprayed compared to when water is sprayed is offset to a decrease in outside air temperature. The temperature of the air extracted from the compressor for cooling has not been a problem in terms of turbine cooling.
特開平１１−７２０２７号公報には、圧縮機吸気温度を制御する方法として、ガスタービン設備の排気を圧縮機入口に誘導することで圧縮機吸気温度を制御するシステムが開示されている。 Japanese Patent Application Laid-Open No. 11-72027 discloses a system for controlling the compressor intake temperature by guiding the exhaust of the gas turbine equipment to the compressor inlet as a method of controlling the compressor intake temperature.
特開平１１−２８０４９４号公報には、圧縮機出口吐出空気を抽気し、水蒸気発生装置で水を蒸発させ圧縮機吸気の一部とすることが開示されている。ここでは、圧縮機吸気温度が低く、水蒸気が氷結する恐れがある場合、水蒸気発生装置への水の供給を停止し蒸気を圧縮機入口へ誘導しない装置となっている。 Japanese Patent Application Laid-Open No. 11-280494 discloses that air discharged from a compressor outlet is extracted and water is evaporated by a steam generator to form part of the compressor intake air. Here, when the compressor intake air temperature is low and there is a possibility that the water vapor freezes, the water supply to the water vapor generating device is stopped and the vapor is not guided to the compressor inlet.
本発明の目的は、外気吸気温度への依存度が低い圧縮機吸気への加湿方法と、圧縮機吸気の温度または湿度制御におけるエネルギー損失の低減が可能な設備およびその運転方法を提供することにある。 An object of the present invention is to provide a method for humidifying compressor intake air, which is less dependent on the outside air intake temperature, a facility capable of reducing energy loss in controlling the temperature or humidity of the compressor intake air, and a method for operating the same. is there.

本発明によると、外気吸気温度への依存度が低い圧縮機吸気への加湿方法と、圧縮機吸気の温度または湿度制御におけるエネルギー損失の低減が可能な設備およびその運転方法を提供できる。 ADVANTAGE OF THE INVENTION According to this invention, the humidification method to the compressor intake with the low dependence on external air intake temperature, the equipment which can reduce the energy loss in the temperature or humidity control of a compressor intake, and its operating method can be provided.
圧縮機吸気に水噴霧するガスタービンシステムでは、冬期のように外気温度が低下して液滴が凍結する恐れがあり水噴霧を停止した場合には、圧縮機に供給される空気の湿分が低下し、圧縮機で圧縮された空気温度が上昇する。この時、タービン冷却空気として用いられることがある圧縮機吐空気温度が上昇し、タービン冷却効率の低下を招く恐れがある。それと同時に燃焼器での燃料流量，増湿器での増湿率の変動が大きくなり、プラントの信頼性が低下する。そこで、外気温度によらず、圧縮機吸気に加湿する装置が必要となる。圧縮機入口温度または湿度を制御する従来技術として、圧縮機吐出空気を圧縮機入口に誘導する方法やタービン通過後の排ガスを圧縮機入口に誘導する方法が提案されてきた。これらの方法を用いた場合、高エネルギー状態の流体を圧縮機吸気の加湿と温度制御に利用できるレベルにまでエネルギーを開放してやる必要があり、系の内部でエネルギー損失が発生する要因となる。本発明が解決する課題は外気吸気温度への依存度が低い圧縮機吸気への加湿方法と、圧縮機吸気の温度または湿度制御におけるエネルギー損失の低減である。以下、本発明の実施形態を図面を用いて示す。 In a gas turbine system that sprays water on the compressor intake air, the temperature of the outside air may drop and the droplets may freeze as in winter. The temperature of air compressed by the compressor increases. At this time, the compressor discharge air temperature, which is sometimes used as turbine cooling air, rises, and there is a risk of lowering the turbine cooling efficiency. At the same time, fluctuations in the fuel flow rate in the combustor and the humidification rate in the humidifier increase, and the reliability of the plant decreases. Therefore, a device for humidifying the compressor intake air is required regardless of the outside air temperature. As conventional techniques for controlling the compressor inlet temperature or humidity, there have been proposed a method of guiding compressor discharge air to the compressor inlet and a method of guiding exhaust gas after passing through the turbine to the compressor inlet. When these methods are used, it is necessary to release the energy of the fluid in a high energy state to a level that can be used for humidification and temperature control of the compressor intake air, which causes energy loss inside the system. The problem to be solved by the present invention is a method of humidifying the compressor intake air having a low dependence on the outside air intake temperature, and a reduction in energy loss in the compressor intake air temperature or humidity control. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

本実施例では、空気冷却器（４）で吸熱された後の圧縮機吐出空気を抽気し、水噴霧装置（９）への気体を誘導する経路（１４）に送ることを特徴としている。ガスタービンの圧縮機吐出空気を抽気し、そのまま圧縮機入口に誘導した場合、圧縮機吐出空気は高温高圧の気体であるため、放熱と運動エネルギーの消散の二つのプロセスが必要になりエネルギー損失が大きい。本実施例では圧縮機出口の高温空気を空気冷却器（４）に通すことで吸熱し、別のエネルギーに変換している。また吸熱された空気冷却器（４）の吐出空気の運動エネルギーは経路（１４）に誘導され水の微粒化に用いられる。この空気冷却器（４）の吐出空気の運動エネルギー分は従来技術での水の微粒化に用いられるエネルギーの削減に用いられる。従って、本特許により系のエネルギー損失を小さくし、システムの高効率化を行うと同時に、圧縮機吸気の湿度，温度を制御することが出来る。 The present embodiment is characterized in that the compressor discharge air that has been absorbed by the air cooler (4) is extracted and sent to the path (14) for guiding the gas to the water spray device (9). When the gas discharged from the compressor of the gas turbine is extracted and guided to the compressor inlet as it is, the compressor discharge air is a high-temperature and high-pressure gas, so two processes of heat dissipation and kinetic energy dissipation are required, resulting in energy loss. large. In this embodiment, high-temperature air at the compressor outlet is passed through the air cooler (4) to absorb heat and convert it into other energy. The kinetic energy of the discharged air from the air cooler (4) that has absorbed heat is guided to the path (14) and used for atomization of water. The kinetic energy of the air discharged from the air cooler (4) is used to reduce energy used for atomization of water in the prior art. Therefore, this patent makes it possible to reduce the energy loss of the system, increase the efficiency of the system, and control the humidity and temperature of the compressor intake air.
空気冷却で回収する熱量を制御と、空気冷却器（４）を通過した圧縮機吐出空気は季節によらず、温度変動が少ない高圧空気となる。そうすると、水噴霧装置（９）を通過後、空気冷却器（４）を通過後に、経路（１４）を通り水噴霧装置（９）に供給される高圧空気も温度変動が少なくなり、圧縮機吸気温度を制御しやすくなる。 When the amount of heat recovered by air cooling is controlled, the compressor discharge air that has passed through the air cooler (4) becomes high-pressure air with little temperature fluctuation regardless of the season. Then, after passing through the water spraying device (9) and after passing through the air cooler (4), the high-pressure air supplied to the water spraying device (9) through the path (14) has less temperature fluctuation, and the compressor intake air It becomes easier to control the temperature.

A flow rate regulator (22) for adjusting the flow rate of gas passing through the path (23), the path (23), and the path ( 23) a temperature measuring device (21 The flow rate regulator (12), the flow rate regulator (11), and the flow rate regulation are configured from the information of the temperature meter (21), the temperature meter (19), the flow rate meter (18), and the temperature meter (21). The amount of water sprayed by the water spraying device (9) and the amount of water sprayed by the water spraying device (8) are adjusted by using a flow rate control device for controlling the flow rate regulator (13) and the flow rate regulator (22). Adjust inlet air temperature and inlet air humidity.
流量調節器（１２），（１３），（２２）を用いて水噴霧装置（９）からの水噴霧を停止することができる。また、流量調節器（１１）を用いて水噴霧装置（８）からの水噴霧を停止することができる。水噴霧装置（８），（９）の両方を同時に作動させることも、両方同時に停止することも、また、どちらかを作動させることも可能である。外気温度が０度以上であり、噴霧した液滴が氷結する恐れが無い場合、水噴霧装置（８）のみで水噴霧を行ってもよい。この時、水噴霧装置（９）の機能は停止させる。外気温度が氷点下になり、噴霧した液滴が氷結する恐れがある場合、水噴霧装置（８）は停止させ、水噴霧装置（９）のみを起動させる。水噴霧装置（９）に誘導させる高温空気の効果で、圧縮機（１）に誘導される温度が上昇し、噴霧した液滴の氷結を抑制できる。従って、外気が氷点下の場合でも圧縮機吸気温度を上昇させ、液滴が氷結しないように圧縮機に誘導し、圧縮機前段側で蒸発潜熱の効果が得られ中間冷却器と同様の効果が得られる。それにより圧縮機吐出空気の急激な温度上昇を抑制できる。 Water spray from the water spray device (9) can be stopped using the flow rate regulators (12), (13), (22). Moreover, the water spray from the water spray device (8) can be stopped using the flow controller (11). Both water spray devices (8), (9) can be activated simultaneously, both can be stopped simultaneously, or either can be activated. When the outside air temperature is 0 ° C. or higher and there is no fear that the sprayed droplets freeze, the water spray may be performed only with the water spray device (8). At this time, the function of the water spray device (9) is stopped. When the outside air temperature becomes below freezing point and the sprayed droplets may freeze, the water spray device (8) is stopped and only the water spray device (9) is started. The temperature induced by the compressor (1) rises due to the effect of high-temperature air induced by the water spray device (9), and icing of the sprayed droplets can be suppressed. Therefore, even when the outside air is below freezing point, the intake temperature of the compressor is raised and the droplet is guided to the compressor so that it does not freeze. It is done. Thereby, a rapid temperature rise of the compressor discharge air can be suppressed.
外気温度によって水噴霧装置（８），（９）を使い分けることにより、常に圧縮機吸気に氷結しない液滴噴霧が可能になる。この結果、圧縮機吐出空気温度の変動が小さくなると同時にタービン冷却効率の変動を抑えることが出来る。また、タービンの熱負荷を抑制し、ローターの信頼性向上にも効果がある。 By properly using the water spraying devices (8) and (9) depending on the outside air temperature, it is possible to spray droplets that are not always frozen in the compressor intake air. As a result, the fluctuation of the compressor cooling air temperature becomes small and the fluctuation of the turbine cooling efficiency can be suppressed. In addition, the thermal load of the turbine is suppressed, and the reliability of the rotor is improved.
圧縮機吐出空気の温度変動が小さくなることにより、増湿器（５）の増湿率も安定し、燃焼器（７）で使用する燃料流量制御も容易になる。従って、プラントの信頼性も向上に寄与する。 By reducing the temperature fluctuation of the compressor discharge air, the humidification rate of the humidifier (5) is stabilized, and control of the fuel flow rate used in the combustor (7) is facilitated. Therefore, plant reliability also contributes to improvement.
外気温度が氷点下を大きく下回る場合、流量調節器（２２）を用いて空気冷却器（４）通過前の圧縮機抽気を水噴霧装置（９）に誘導する。これにより、水噴霧装置（９）に供給する空気温度を上昇させ、外気温度が氷点下を大きく下回る場合にも圧縮機入口温度を０度以上にすることができ、圧縮機吸気に液滴噴霧が出来る。この機能により、外気温度が氷点下を大きく下回る環境下においても、圧縮機吐出空気温度の上昇を防ぐことができ、タービンの冷却効率の維持，ローター，プラント性能の信頼性向上に寄与する。 When the outside air temperature is significantly below the freezing point, the compressor bleed air before passing through the air cooler (4) is guided to the water spray device (9) using the flow rate regulator (22). As a result, the temperature of the air supplied to the water spray device (9) is raised, and the compressor inlet temperature can be set to 0 ° C. or more even when the outside air temperature is significantly below the freezing point. I can do it. This function can prevent the compressor discharge air temperature from rising even in an environment where the outside air temperature is well below freezing point, and contributes to maintaining the cooling efficiency of the turbine and improving the reliability of the rotor and plant performance.
効率よく、吸気温度をむらなく均一にするためには吸気ダクト断面に均一に熱源となる水噴霧装置（９）を配置する必要がある。この時、水噴霧装置（９）の経路（１４）に誘導される高温アシスト空気として、ある一定以上の空気流量が必要となる。数百度の圧縮機吐出空気を水噴霧装置（９）に誘導する場合、水噴霧装置（９）に誘導した水が蒸発し液滴を圧縮機に誘導できなくなると同時に圧縮機吸気温度も高くなりすぎるため冷却のプロセスが別途必要になる。また、圧力比により圧縮機吐出空気温度は変化し、また、水噴霧装置（９）に必要な高温アシスト空気流量は一定であるので、圧縮機吸気温度を制御するためには水噴霧装置（９）で使用する二流体ノズル本数を調整する必要がある。二流体ノズルとは水噴霧装置（９）に誘導される空気で、同じく水噴霧装置（９）に誘導される水を粉砕し微粒化する装置である。本実施例のガスタービン設備では空気冷却器通過後の空気は水噴霧装置（９）で利用後、液滴が蒸発しない程度の温度であるため液滴噴霧の効果を利用できる。この機能により、噴霧された液滴の蒸発潜熱を利用し圧縮空気の温度上昇が抑えられ、中間冷却器と同様の効果が得られる。 In order to efficiently and uniformly make the intake air temperature uniform, it is necessary to dispose a water spray device (9) as a heat source uniformly on the cross section of the intake duct. At this time, an air flow rate higher than a certain level is required as the high-temperature assist air guided to the path (14) of the water spray device (9). When the compressor discharge air of several hundred degrees is guided to the water spraying device (9), the water guided to the water spraying device (9) evaporates and the droplets cannot be guided to the compressor, and at the same time, the compressor intake temperature increases. Therefore, a cooling process is required separately. Further, since the compressor discharge air temperature varies depending on the pressure ratio, and the high-temperature assist air flow rate required for the water spray device (9) is constant, the water spray device (9) is used to control the compressor intake air temperature. It is necessary to adjust the number of two-fluid nozzles used in step (1). The two-fluid nozzle is an air that is guided to the water spray device (9), and is a device that pulverizes and atomizes the water that is also guided to the water spray device (9). In the gas turbine equipment of the present embodiment, the air after passing through the air cooler is at a temperature at which the droplets do not evaporate after being used by the water spray device (9), so that the effect of droplet spraying can be used. With this function, the temperature rise of the compressed air is suppressed using the latent heat of vaporization of the sprayed droplets, and the same effect as the intermediate cooler can be obtained.

Further, the combined use of the water spray device (9) has an advantage that the inlet air temperature and the inlet air humidity of the compressor can be adjusted using two types of water spray devices according to the outside air temperature conditions.
