Description

【0001】
【発明の属する技術分野】
本発明は、使用済みの天ぷら油や賞味期限切れの食用油を燃料とするガスタービン発電設備に関するものである。
【0002】
【従来の技術】
発電設備として、排気ガス中に含まれるNOx排出量が少量等の理由により広く普及されつつあるが、その中でも分散型電源の一環としてマイクロガスタービンが注目されている。このマイクロガスタービンに使用される燃料としては、LNG,LPGのガス系のものと、このガス系燃料よりも比較的に安価な軽油や灯油の液系のものが使用される。
一方、環境及び資源の有効活用として、天ぷら廃油を改質してメチルエステルとし、これをディーゼル車の燃料とする試みがいくつかの自治体や民間企業において検討されている。
【0003】
【発明が解決しようとする課題】
天ぷら廃油を改質してメチルエステルとしてディーゼル車の燃料とした場合、その排ガスに異臭が発生し、しかも、その排ガス中にはアルデヒド等の有害物質が含まれる可能性がある。
また、この改質油は引火点が高いことにより、軽油と混合して利用することも考えられるが、混合した場合には軽油税が適用されるために高価な燃料となる等の問題を有している。
【0004】
本発明は、かかる点に鑑みてなされたもので、その目的とするところは使用済み天ぷら油をガスタービンの燃料とする発電設備を提供することにある。
【0005】
【課題を解決するための手段】
本発明は、ガスタービン始動時には液体燃料を供給し、所定の燃焼時間経過後でガスタービンの燃焼室温度が植物油の引火点温度180〜190℃となったときにメチルエステルに改質された使用済み植物油を燃料とするガスタービン発電設備において、
前記ガスタービンをマイクロガスタービンとすると共に、前記液体燃料を貯留する液体燃料タンクと植物油を貯留する植物油タンクを併設し、各タンクからの送出管路にそれぞれ電磁弁とストレーナを配設し、この送出管路のタンクとは反対側を、燃料供給管路に結合して接続し、この燃料供給管路にチャッキ弁、ポンプ及びフィルターを介して前記マイクロガスタービンを連結し、且つフィルターとマイクロガスタービン間の燃料供給管路と前記タンクからポンプへの燃料供給管路に、燃料供給圧力一定保持のリリーフバルブと、このリリーフバルブからの燃料を貯留して前記ポンプに供給するリザーバタンクを設けたことを特徴としたものである。
【0007】
本発明の第2は、前記植物油貯留タンクと液体燃料タンクに設けられた弁体は、それぞれ燃料供給管を介して各別の調圧機能部に連結され、各調圧機能部より前記ガスタービンに燃料を供給するよう構成したことを特徴とした
【0008】
本発明の第3は、前記ガスタービンへの燃料供給は、液体燃料若しくは気体燃料を先に供給した後に、使用済み植物油としたことを特徴としたものである。
【0010】
【発明の実施の形態】
図1は、本発明の実施形態を示す構成図を示したもので、1は改質された使用済み天ぷら油や賞味期限切れの食用油(以下これら各油を単に植物油という)を貯留する植物油タンク、2は灯油や軽油等を貯留する液体燃料タンク(以下灯油で代表する)で、これら各タンクの送出管路10,20にはそれぞれ弁体としての電磁弁11,21とストレーナ12,22が配設されている。送出管路10,20の先端は燃料供給管路3の一端に連接されいおり、また、この燃料供給管路3の他端には調圧機能部4が連接されている。調圧機能部4は、ポンプ41,フィルター42及びガスタービンへの燃料の供給圧力を所定値に維持するためのリリーフバルブ43とリザーバタンク44を有しており、リザーバタンクを流出した油はポンプ41に返却される。
【0011】
5はガスタービンでマイクロガスタービンが使用され、フィルター42を通った燃料がガスタービンに供給される。このガスタービン5は、図示省略されているが燃焼室や圧縮機,発電機等を有したシステム構成となっている。6は燃料供給管路3に挿入されたチャッキベン弁で、供給される燃料量が前もって調整される。7はガスタービンへの燃料供給管に設けられた圧力ゲージである。
【0012】
【表1】

Figure 0003896843
【0013】
表1は、改質植物油(改質天ぷら油)の一般的な物性を示したものである。
これによると、引火点は180〜190℃と高いためにガスタービンをコールドスタートさせることは出来ない。
そのため、ガスタービンの始動時には、電磁弁21の流路を開路することによって電磁弁21,チャッキベン弁6、ポンプ41およびフィルター42を通ってガスタービン5に灯油を供給し、この灯油によりガスタービンをスタートさせる。このとき、リリーフバルブ43は、ガスタービンに供給される燃料が所定値となるよう微調整し、余分な燃料をリザーバタンク44を介してポンプ41の流入側に送出する。
【0014】
任意時間が経過後、電磁弁21を閉じて11の流路を開路してガスタービンへの供給燃料を切り換える。以下灯油時と同様にして植物油が燃料としてガスタービン5に供給される。このとき、植物油に混入している比較的大きな異物は、ストレーナ12によって阻止される。このストレーナ12を濾過した植物油はポンプ41を介してフィルター42で再度濾過され、このフィルターにて小さな異物が除去される。
なお、燃料として使用される使用済みの植物油は廃油であるので量には限界がある。したがって、植物油タンク1に貯留された植物油がなくなったときには、電磁弁を再度切り換えて燃料を灯油としてガスタービン5に供給する。
【0015】
ところで、改質された植物油から灯油に切り換えたときには次のような問題が生じる。植物油の油脂は、グリセリンに3つの脂肪酸が結合したトリアシルグリセリンが多数集まった混合物であり、グリセリンを含むことから粘度が高いものとなっている。そこで燃料として利用するには、アルカリ触媒を用いたメタノールとのエステル交換反応によってグリセリンと脂肪酸エステルにより分ける必要がある。このときのグリセリン除去をおこなうために水で洗浄するが、そのとき燃料となる脂肪酸エステルに水が混入する惧れがある。水が混入すると、極性の低い灯油と混ぜ合わさることによって乳化するため、図1の実施形態においては、フィルター点線で示す42‘の位置に配設した場合、乳化した燃料がフィルターに詰まり、燃料を供給出来ない惧れが生じる。そのため、本発明ではポンプ41の吐出側にフィルター42を挿入することにより、乳化現象が発生してフィルター42に付着してもポンプ41の吐出圧でガスタービン5の燃焼室に送出してフィルター42の目詰まりを防止している。
【0016】
図2は、図1の構成による実験を示したもので、植物油として改質天ぷら油を使用したものである。
図2において、123分まではガスタービン5の燃料を灯油とし、それ以後は改質天ぷら油としたものである。同図によると、燃料を改質天ぷら油に切り換えた後の125分過ぎにガスタービンの温度と出力に変動現象が発生している。
この現象は、調圧機能部4に残存していた灯油と改質天ぷら油とが撹拌されて乳化したことによりガスタービンへの燃料供給が抑制された結果である。この程度の変動現象では実用的には差し支えないが、次にこの変動現象を防止して、円滑な燃料供給を行うための構成を図3に基づいて説明する。
【0017】
図3において、4a,4bはそれぞれ調圧機能部で、図1で示す調圧機能部の部材をそれぞれ備えている。
すなわち、図3では灯油の供給ルートと植物油の供給ルートとを個別に設けてそれぞれに調圧機能を持たせ、この調圧機能部のリザーバタンク44a,44b等における灯油と植物油との撹拌現象を防止して乳化を抑制したものである。
図3の構成における実験によると、図2で示すようなガスタービンの変動現象が生じないことを確認できた。
【0018】
図4は更に他の実施形態を示したもので、灯油に代えて都市ガス等のガス系を使用したものである。同図において50はLNG,LPGのガス系燃料、51は昇圧機で、この昇圧機において都市ガスの圧力を3kgf/cm2程度に昇圧する。23,52はチャッキ弁、24,53は電磁弁である。なお、図1又は図3と同一若しくは相当部分には同符号を付してその説明を省略する。
この例の場合、先ず都市ガス等の気体燃料50を昇圧機51によって昇圧した後にチャッキ弁52,電磁弁53を介してガスタービン5に供給してこのガスタービンを始動する。ガスタービン5の燃焼室温度が上昇し、植物油の引火点以上に上昇して植物油が着火しやすい状態となったときに電磁弁53を閉じ、電磁弁21,24の流路を開路することによって植物油をガスタービンに供給する。
【0019】
図5は、図4の構成による実験例を示したもので、植物油は改質天ぷら油を使用した。
図5によると、気体燃料によって始動されてから144分経過し、ガスタービンの燃焼室温度が200℃近辺時に気体燃料から改質天ぷら油に切換えたものである。この切換えは、気体−液体への切換えとなるので、液体−液体切換えのように連続切換えとはならず一度燃焼は途切れるが、燃焼室は十分に温度上昇しているので改質天ぷら油は着火される。改質天ぷら油に切換えて148分までは発電機出力30kWで運転し、それ以後は改質天ぷら油における運転状態確認のために160分までを15kWの出力運転とし、更に、その状態より160分において改質天ぷら油から灯油に切換て運転実験をした。その結果、何れの場合においても安定した運転状態が得られ、エンジンスピードや発電機出力は、燃料切換えに基づく悪影響は一切生じないことが確認できた。
【0020】
【発明の効果】
以上のとおり、本発明によれば、マイクロガスタービンの始動時には灯油等の低引火温度燃料で始動し、その後に廃植物油に切り換えて発電するようにしたものであるから、発電コストが低下するばかりでなく、環境面及び資源の有効活用が図られるものである。しかも、廃植物油と灯油とを混合撹拌すると乳化現象が生じるが、この乳化現象の生じる燃料を使用しても、ガスタービンへの燃料供給を所定圧力に維持しながら発電できるものである。

[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing an embodiment of the present invention, wherein 1 is a vegetable oil tank for storing modified used tempura oil or edible oil that has expired (hereinafter, these oils are simply referred to as vegetable oils). 2 is a liquid fuel tank (hereinafter represented by kerosene) for storing kerosene, light oil, and the like. The delivery pipes 10 and 20 of these tanks have solenoid valves 11 and 21 and strainers 12 and 22 as valve bodies, respectively. It is arranged. The leading ends of the delivery pipes 10 and 20 are connected to one end of the fuel supply pipe 3, and the pressure regulating function unit 4 is connected to the other end of the fuel supply pipe 3. The pressure regulating function unit 4 has a relief valve 43 and a reservoir tank 44 for maintaining the supply pressure of fuel to the pump 41, the filter 42 and the gas turbine at a predetermined value, and the oil that has flowed out of the reservoir tank is pumped Returned to 41.
[0011]
A gas turbine 5 is a micro gas turbine, and the fuel that has passed through the filter 42 is supplied to the gas turbine. Although not shown in the figure, the gas turbine 5 has a system configuration including a combustion chamber, a compressor, a generator, and the like. Reference numeral 6 denotes a chuck-ben valve inserted in the fuel supply line 3, and the amount of fuel to be supplied is adjusted in advance. Reference numeral 7 denotes a pressure gauge provided in a fuel supply pipe to the gas turbine.
[0012]
[Table 1]
Figure 0003896843
[0013]
Table 1 shows the general physical properties of the modified vegetable oil (modified tempura oil).
According to this, since the flash point is as high as 180 to 190 ° C., the gas turbine cannot be cold started.
Therefore, when the gas turbine is started, kerosene is supplied to the gas turbine 5 through the solenoid valve 21, the chuck valve 6, the pump 41, and the filter 42 by opening the flow path of the solenoid valve 21, and the gas turbine is driven by this kerosene. Start it. At this time, the relief valve 43 finely adjusts the fuel supplied to the gas turbine to a predetermined value, and sends excess fuel to the inflow side of the pump 41 via the reservoir tank 44.
[0014]
After an arbitrary time has elapsed, the solenoid valve 21 is closed and the flow path 11 is opened to switch the fuel supplied to the gas turbine. Thereafter, vegetable oil is supplied to the gas turbine 5 as fuel in the same manner as in kerosene. At this time, the relatively large foreign matter mixed in the vegetable oil is blocked by the strainer 12. The vegetable oil filtered through the strainer 12 is filtered again by the filter 42 via the pump 41, and small foreign matters are removed by this filter.
In addition, since the used vegetable oil used as a fuel is waste oil, there is a limit in quantity. Therefore, when the vegetable oil stored in the vegetable oil tank 1 runs out, the solenoid valve is switched again to supply fuel to the gas turbine 5 as kerosene.
[0015]
By the way, when switching from the modified vegetable oil to kerosene, the following problems arise. The oil of vegetable oil is a mixture of a large number of triacylglycerols in which three fatty acids are bonded to glycerol, and has a high viscosity because it contains glycerol. Therefore, in order to use it as a fuel, it is necessary to separate glycerin and fatty acid ester by transesterification with methanol using an alkali catalyst. In order to remove the glycerin at this time, it is washed with water. At that time, there is a possibility that water is mixed into the fatty acid ester as the fuel. When water is mixed, it is emulsified by mixing with kerosene having a low polarity. Therefore, in the embodiment shown in FIG. 1, when the filter is disposed at a position 42 'indicated by a dotted line, the emulsified fuel is clogged in the filter, and the fuel There is a fear that it will not be possible to supply. Therefore, in the present invention, by inserting the filter 42 on the discharge side of the pump 41, even if an emulsification phenomenon occurs and adheres to the filter 42, the filter 42 is sent to the combustion chamber of the gas turbine 5 with the discharge pressure of the pump 41. To prevent clogging.
[0016]
FIG. 2 shows an experiment according to the configuration of FIG. 1, in which modified tempura oil is used as a vegetable oil.
In FIG. 2, the fuel of the gas turbine 5 is used as kerosene for up to 123 minutes, and then the modified tempura oil is used. According to the figure, a fluctuation phenomenon occurs in the temperature and output of the gas turbine after 125 minutes after the fuel is switched to the reformed tempura oil.
This phenomenon is a result of suppression of fuel supply to the gas turbine due to the stirring and emulsification of kerosene and modified tempura oil remaining in the pressure adjusting function unit 4. Although such a fluctuation phenomenon may be practically used, a configuration for preventing this fluctuation phenomenon and performing smooth fuel supply will be described with reference to FIG.
[0017]
In FIG. 3, reference numerals 4a and 4b denote pressure regulating function units, each having a member of the pressure regulating function unit shown in FIG.
In other words, in FIG. 3, a kerosene supply route and a vegetable oil supply route are provided separately to provide a pressure regulating function, and the stirring phenomenon of kerosene and vegetable oil in the reservoir tanks 44a, 44b, etc. of this pressure regulating function portion is illustrated. This is to prevent emulsification.
According to the experiment in the configuration of FIG. 3, it has been confirmed that the fluctuation phenomenon of the gas turbine as shown in FIG. 2 does not occur.
[0018]
FIG. 4 shows still another embodiment in which a gas system such as city gas is used instead of kerosene. In the figure, 50 is a gas fuel of LNG and LPG, 51 is a booster, and the pressure of the city gas is increased to about 3 kgf / cm 2 in this booster. Reference numerals 23 and 52 denote check valves, and reference numerals 24 and 53 denote electromagnetic valves. The same or corresponding parts as those in FIG. 1 or FIG.
In this example, the gas fuel 50 such as city gas is first boosted by the booster 51 and then supplied to the gas turbine 5 via the check valve 52 and the electromagnetic valve 53 to start the gas turbine. When the temperature of the combustion chamber of the gas turbine 5 rises and rises above the flash point of the vegetable oil and the vegetable oil is easily ignited, the solenoid valve 53 is closed and the flow paths of the solenoid valves 21 and 24 are opened. Supply vegetable oil to the gas turbine.
[0019]
FIG. 5 shows an experimental example with the configuration of FIG. 4, and modified tempura oil was used as the vegetable oil.
According to FIG. 5, 144 minutes have elapsed since the start with the gas fuel, and the gas turbine is switched from the gas fuel to the reformed tempura oil when the combustion chamber temperature of the gas turbine is around 200 ° C. Since this switching is to gas-liquid switching, it is not continuous switching like liquid-liquid switching, and combustion is interrupted once, but the temperature of the combustion chamber has risen sufficiently so that the modified tempura oil is ignited. Is done. Switch to modified tempura oil and operate at a generator output of 30 kW for up to 148 minutes. After that, to confirm the operating condition of the modified tempura oil, the operation is up to 160 kW for output of 15 kW, and 160 minutes from that state. The operation experiment was carried out by switching from modified tempura oil to kerosene. As a result, it was confirmed that in any case, a stable operating state was obtained, and the engine speed and the generator output did not have any adverse effects due to the fuel switching.
[0020]
【The invention's effect】
As described above, according to the present invention, when the micro gas turbine is started, it is started with low flammable temperature fuel such as kerosene, and then it is switched to waste vegetable oil to generate power. Rather, the environment and resources can be effectively utilized. Moreover, when waste vegetable oil and kerosene are mixed and agitated, an emulsification phenomenon occurs. Even when fuel that causes this emulsification phenomenon is used, power generation can be performed while maintaining the fuel supply to the gas turbine at a predetermined pressure.
