Abstract
Description
本発明は、ガスタービンの吸気を冷却する水冷式のガスタービン吸気冷却装置およびガスタービン設備に関する。 The present invention relates to a water-cooled gas turbine intake cooling device and gas turbine equipment for cooling intake air of a gas turbine.
ガスタービンを運転するにあたり、圧縮機に取込まれる吸気を冷却し発電効率を上げる試みが以前からなされている。従来技術では、ガスタービン吸気フィルタ室の吸気口の全面をカバーするように設置されたメディアに給水を供給し、このメディアを吸気が通過する際に水の蒸発潜熱で吸気を冷却する方法（特許文献１）や、LNGを吸気ダクト中に配置した蒸発電熱管群に導き、LNGの気化熱で吸気を冷却する方法（特許文献２）も提案されている。 At the time of operating a gas turbine, attempts have been made to improve the power generation efficiency by cooling the intake air taken into the compressor. In the prior art, water is supplied to a medium installed so as to cover the entire intake port of the gas turbine intake filter chamber, and when the intake air passes through this medium, the intake air is cooled by the latent heat of evaporation of the water (patented) Document 1) and a method of cooling LNG by evaporating heat of LNG by guiding LNG to an evaporation electric tube group arranged in an intake duct (Patent Document 2) have also been proposed.
ところで、ガスタービンの吸気冷却を顕熱による熱交換を利用した水冷式の吸気冷却装置とし、さらに冷却水に海水や河川水を用いる場合、取水された冷却水は大気温度の影響を受けているため、実際に冷却に使用したい夏季や高温時には外気と取水の温度差が小さく、十分な冷却効果が得られないという課題があった。 By the way, when the intake air cooling of the gas turbine is a water-cooled intake air cooling device using heat exchange by sensible heat and seawater or river water is used as the cooling water, the intake cooling water is affected by the atmospheric temperature. Therefore, there is a problem that the temperature difference between the outside air and the water intake is small during summer and high temperatures that are actually desired for cooling, and a sufficient cooling effect cannot be obtained.
そこで、本発明の目的は、顕熱による吸気冷却の冷却水として海水や河川水を用いる場合でも、大気温度の上昇による冷却水への影響を低減することができるガスタービン吸気冷却装置及びガスタービン設備を提供することにある。 Accordingly, an object of the present invention is to provide a gas turbine intake air cooling device and a gas turbine that can reduce the influence on the cooling water due to an increase in the atmospheric temperature even when seawater or river water is used as the cooling water for intake air cooling by sensible heat. To provide facilities.
上記目的を達成するために、本発明は、吸気ダクト内でガスタービンの吸気を冷却するガスタービン吸気冷却装置において、海又は河川から取水した冷却水を前記吸気ダクトを経由して前記海又は河川に戻す循環水配管を備え、前記循環水配管の取水源から前記吸気ダクトまでの間の地中埋設部、および前記吸気ダクト内に導入された前記循環水配管のダクト内配置部にヒートパイプを設けたことを特徴とする。 In order to achieve the above object, the present invention provides a gas turbine intake air cooling device that cools the intake air of a gas turbine in an intake duct, wherein cooling water taken from the sea or river is supplied to the sea or river via the intake duct. A circulating water pipe that returns to the ground, and a heat pipe is provided in the underground buried part between the intake of the circulating water pipe and the intake duct, and in the duct arranged part of the circulating water pipe introduced into the intake duct. It is provided.

［第１実施形態］
図１は第１実施形態における吸気冷却装置を適用したガスタービンの概略構成を示した側面模式図である。
Embodiments according to the present invention will be described below with reference to the drawings.
[First Embodiment]
FIG. 1 is a schematic side view showing a schematic configuration of a gas turbine to which an intake air cooling apparatus according to a first embodiment is applied.
ガスタービン設備の基本構成としては、図１に示すように、吸気を圧縮する圧縮機２と、燃焼ガスを生成する燃焼器３と、燃焼ガスにより駆動されるタービン１である。 As shown in FIG. 1, the basic configuration of the gas turbine equipment includes a compressor 2 that compresses intake air, a combustor 3 that generates combustion gas, and a turbine 1 that is driven by the combustion gas.
大気より取込まれる吸気は、吸気ダクト６を通り、圧縮機２に供給される。圧縮機２を通過して圧縮された空気は、燃焼用空気として燃焼器３に供給される。燃焼器３で燃料を燃焼させて発生した高温高圧の燃焼ガスはタービン１に供給され、同タービン１内で膨張する際にタービン１を回転させて軸出力が発生する。 The intake air taken from the atmosphere passes through the intake duct 6 and is supplied to the compressor 2. The air compressed through the compressor 2 is supplied to the combustor 3 as combustion air. High-temperature and high-pressure combustion gas generated by burning fuel in the combustor 3 is supplied to the turbine 1, and when expanding in the turbine 1, the turbine 1 is rotated to generate shaft output.
吸気フィルタ室１０内には、吸気口７から取り込まれる大気中の粉塵等を捕集して除去する吸気フィルタ９が収容設置される。 In the intake filter chamber 10, an intake filter 9 that collects and removes atmospheric dust and the like taken from the intake port 7 is accommodated and installed.
そして、吸気ダクト６は吸気フィルタ室１０の下流端と圧縮機２とを接続する空気流路を形成する。 The intake duct 6 forms an air flow path connecting the downstream end of the intake filter chamber 10 and the compressor 2.
また、吸気ダクト６には、その中途位置に吸気音を低減させる吸気サイレンサ８が設置されている。 The intake duct 6 is provided with an intake silencer 8 for reducing intake noise at a midway position.
循環水配管４は海または河川から取水し、地中を通り、吸気ダクト内を通り、地上を通り海または河川へ戻るようにルーティングされる。なお、本実施例では、冷却水の取水部から吸気ダクトまでの間の区間で地中に埋設される循環水配管部分を地中埋設部４ａ、吸気ダクト６内に導入された循環水配管部分をダクト内配置部４ｂと称する。 The circulating water pipe 4 takes water from the sea or river, and is routed through the ground, through the intake duct, through the ground, and back to the sea or river. In this embodiment, the circulating water pipe portion embedded in the ground in the section from the intake portion of the cooling water to the intake duct is the circulating water piping portion introduced into the underground portion 4 a and the intake duct 6. Is referred to as an in-duct arrangement portion 4b.
このように、取水源から取水した冷却水を吸気ダクト経由で、再び海又は河川に戻すように構成した循環水配管４には、ヒートパイプ５が設置されている。ヒートパイプ５の設置個所は、循環水配管４の地中埋設部４ａ、並びに吸気ダクト内に導入されたダクト内配置部４ｂの二か所であり、それぞれには複数のヒートパイプが設けられる。 Thus, the heat pipe 5 is installed in the circulating water piping 4 configured to return the cooling water taken from the water intake source to the sea or river again via the intake duct. There are two places where the heat pipes 5 are installed: an underground buried part 4a of the circulating water pipe 4 and an in-duct arrangement part 4b introduced into the intake duct, each of which is provided with a plurality of heat pipes.
ヒートパイプ５は前述の通り、循環水配管４の地中埋設部４ａとダクト内配置部４ｂの二か所に設置されている。地中埋設部４ａでは地中と該取水の温度差によって取水した冷却水を冷却する。地中埋設部４ａのヒートパイプ５により冷却された冷却水は、ダクト内配置部４ｂに導かれ、このダクト内配置部４ｂに設けられたヒートパイプ５を介して吸気ダクト内の外気を冷却する。 As described above, the heat pipes 5 are installed at two locations, the underground buried portion 4a and the in-duct arrangement portion 4b of the circulating water piping 4. In the underground buried portion 4a, the cooling water taken is cooled by the temperature difference between the ground and the water taken. The cooling water cooled by the heat pipe 5 of the underground buried portion 4a is guided to the in-duct arrangement portion 4b and cools the outside air in the intake duct via the heat pipe 5 provided in the in-duct arrangement portion 4b. .
ヒートパイプ５の構造を図２に示す。ヒートパイプ内部は減圧され、少量の作動流体１１が封入されている。作動流体１１は高温部１２では蒸発し、周囲の熱をうばった後、温度の違いによって生まれる圧力差によって低温部１３へと移動する。作動流体１１は低温部１３にて液体に戻り、周囲に熱を放出する。その後、液体環流用ウィック１４に生じる毛細管現象によって高温部へと運ばれる。 The structure of the heat pipe 5 is shown in FIG. The inside of the heat pipe is depressurized and a small amount of working fluid 11 is enclosed. The working fluid 11 evaporates in the high temperature part 12 and moves to the low temperature part 13 due to the pressure difference generated by the temperature difference after receiving the ambient heat. The working fluid 11 returns to a liquid at the low temperature part 13 and releases heat to the surroundings. Then, it is carried to a high temperature part by the capillary phenomenon which arises in the wick 14 for liquid recirculation | reflux.
ヒートパイプ内の作動流体１１は、自然現象によって対流し熱を伝達するため、運用するために外部からのエネルギーを必要としない。 Since the working fluid 11 in the heat pipe convects and transfers heat by a natural phenomenon, it does not require external energy to operate.
循環水配管４内は下流側の温度が上流側に対し低くなっている。その温度差によって圧力差が生じ、自然循環するようになっている。 In the circulating water pipe 4, the temperature on the downstream side is lower than that on the upstream side. A pressure difference is generated due to the temperature difference, and natural circulation occurs.
以上のような性質のヒートパイプを循環水配管４の地中埋設部４ａ及びダクト内配置部４ｂに設置することで、海水より温度の低い地中では海水を地中埋設部４ａのヒートパイプ５によって冷却し、吸気ダクト６内では温度の高い吸気（特に夏季の大気温度は海水や河川水より高温）をダクト内配置部４ｂのヒートパイプ５により冷却する。 By installing the heat pipe having the above properties in the underground buried portion 4a and the in-duct arrangement portion 4b of the circulating water piping 4, the sea water is heated in the ground at a temperature lower than that of the sea water. In the intake duct 6, the intake air having a high temperature (especially, the atmospheric temperature in summer is higher than seawater or river water) is cooled by the heat pipe 5 of the in-duct arrangement portion 4b.
一般に、海水や河川水から取水した冷却水をそのまま吸気ダクト内で顕熱を利用して吸気冷却（間接的な熱交換）させた場合、特に吸気冷却を行いたい夏季には大気と冷却水の温度差が小さくなることが想定され、十分な冷却効果を得られないことがある。これに対して、本実施例では冷却水を地中埋設部４ａで冷却した上でダクト内配置部４ｂに供給しているので、取水した冷却水をそのまま用いる場合よりも大気と冷却水の温度差をより大きく取ることが可能となり、特に夏季における吸気冷却の効果を向上させることができる。さらに、本実施例ではヒートパイプ５を介して熱交換を行うため、小さな温度差でも冷却することが可能となる。 In general, when cooling water taken from seawater or river water is directly subjected to intake air cooling (indirect heat exchange) using sensible heat in the intake duct, the air and cooling water are used especially in the summer when intake air cooling is desired. It is assumed that the temperature difference is small, and a sufficient cooling effect may not be obtained. On the other hand, in this embodiment, the cooling water is cooled by the underground buried portion 4a and then supplied to the in-duct arrangement portion 4b. Therefore, the temperature of the atmosphere and the cooling water is higher than when the taken cooling water is used as it is. The difference can be made larger, and the effect of intake air cooling in the summer can be improved. Furthermore, since heat exchange is performed through the heat pipe 5 in this embodiment, it is possible to cool even a small temperature difference.
図３は、本発明の他の実施例であるガスタービン設備の全体概略図を示す。本実施例では、吸気フィルタ９を吸気口７の直ぐ後、つまり吸気ダクト６の入口側に配置し、この吸気フィルタ９の下流側にダクト内配設部４ｂを配置した例である。 FIG. 3 is an overall schematic view of a gas turbine facility according to another embodiment of the present invention. In this embodiment, the intake filter 9 is disposed immediately after the intake port 7, that is, on the inlet side of the intake duct 6, and the in-duct arrangement portion 4 b is disposed on the downstream side of the intake filter 9.
本実施例によれば、吸気フィルタ９で大気中の粉塵等を捕集された後の空気がダクト内配設部４ｂに供給されるため、ダクト内配設部４ｂに設けられるヒートパイプ５の冷却性能の低下を低減することが可能となる。 According to the present embodiment, the air after dust in the atmosphere is collected by the intake filter 9 is supplied to the in-duct arrangement portion 4b, so that the heat pipe 5 provided in the in-duct arrangement portion 4b It is possible to reduce a decrease in cooling performance.
