Description

本発明は、高温高圧の燃焼ガスもしくは蒸気を駆動流体とする高圧タービンに代え、常温常圧の空気を駆動流体に複数プロペラとプロペラ型風車でタービンを構成し、複数プロペラを少ない動力で回転させ大きなエネルギーをもつ風をつくり、この風をプロペラ型風車に受けトルクに転換、出力を調整し、コストの安い電気を発電する低圧タービンによる発電方法とその低圧タービンによる発電装置に関するものである。   The present invention replaces a high-pressure turbine using high-temperature and high-pressure combustion gas or steam as a driving fluid, and forms a turbine with a plurality of propellers and a propeller-type windmill using air at normal temperature and normal pressure as the driving fluid, and rotates the plurality of propellers with less power. The present invention relates to a power generation method using a low-pressure turbine and a power generation apparatus using the low-pressure turbine, which generates wind with large energy, receives the wind into a propeller-type wind turbine, converts the torque into torque, adjusts the output, and generates electricity at low cost.

一般に発電用動力機関として用いられるタービンは低圧タービンである風車、およびスチームタービンならびにガスタービンなどの高圧タービンである。このうち風車は自然の風を駆動流体とするため熱効率は良いが稼動率は低く、また、ロータの回転で発生する反転後流のため複数の風車を同じ回転軸で連結できず、風のエネルギーを大きな出力とするには大口径且つ低速回転と規模が大きくなり建設コストは高く、稼動率が低いことから発電コストを低減するには限度がある。   Turbines that are generally used as power generation engines are wind turbines that are low-pressure turbines, and high-pressure turbines such as steam turbines and gas turbines. Among them, wind turbines use natural wind as the driving fluid, so heat efficiency is good, but the operation rate is low, and because of the reverse wake generated by the rotation of the rotor, it is not possible to connect multiple wind turbines with the same rotating shaft, so wind energy Large output, large rotation, large scale, large construction cost, high construction cost and low operating rate, there is a limit to reducing power generation cost.

一方、高圧タービンは高温高圧の駆動流体を使い、回転翼である動翼の回転で発生した反転後流の回転方向を固定翼である静翼で補正することにより複数動翼を同じ回転軸で連結し回転数を速め、風車に比べ高い稼動率と小さな規模で大きな出力にすることができるが、駆動流体が高温高圧のため機構が複雑となり機器製造費用は高く、また、駆動流体を高温高圧にするために使用した燃料の燃焼による発生熱量のほとんどをタービン外に排出するため熱効率は低く、発電コストは高い。   On the other hand, a high-pressure turbine uses a high-temperature and high-pressure drive fluid, and corrects the rotation direction of the reverse wake generated by the rotation of the rotor blade, which is the rotor blade, by correcting the rotating blades with the same rotating shaft by using the stationary blade, which is a fixed blade. It can be connected and speeded up to achieve a higher operating rate and smaller output than a windmill, but the drive fluid is high temperature and high pressure, so the mechanism is complicated and the equipment manufacturing cost is high. Because most of the heat generated by the combustion of the fuel used to make it is discharged outside the turbine, the thermal efficiency is low and the power generation cost is high.

したがって、発電用動力機関としてのタービンには高圧タービンの稼動率と装置規模、風車の熱効率をもつものが望まれ、また、地球温暖化防止のため二酸化炭素の発生抑制が要請されており、燃焼による二酸化炭素の発生をともなわない駆動流体を使用するタービンが望まれる。このような状況のなかで、これまでにも発電コストを下げるための技術は公開されている。   Therefore, a turbine as a power generation engine that has a high-pressure turbine operating rate, equipment scale, and wind turbine thermal efficiency is desired, and carbon dioxide generation suppression is required to prevent global warming. There is a desire for a turbine that uses a driving fluid that does not involve the generation of carbon dioxide. Under such circumstances, techniques for reducing power generation costs have been disclosed.

例えば、特許文献１には「ハイブリッド風力発電機」として、風の流れ方向に順次直径を拡大し互いに回転方向の異なる３個の風車を直列に配置し、円錐形の外殻で覆うことにより風のエネルギーの損失を抑えるとともに、この外殻に太陽電池を装着し発電量を補充しようとするものである。   For example, Patent Document 1 discloses a “hybrid wind power generator” in which three wind turbines having diameters that are sequentially enlarged in the wind flow direction and different in rotation direction are arranged in series and covered with a conical outer shell. In addition to suppressing the loss of energy, a solar cell is attached to the outer shell to replenish the amount of power generation.

また、特許文献２には「風力発電用発電装置」として、二個のプロペラ型風車を風の流れ方向に直列に配置。前部の風車のロータを発電機の回転子に、後部の風車のロータを回転可能とした発電機の固定子に取付け、前部風車の回転による反転後流を受けた後部風車が前部風車に対し逆方向に回転することを利用し、発電機の回転子と固定子を異なる方向に回転させ、回転数を増やし発電機の出力と回転速度の比例関係から、同一規模の発電機の発電量を増し、もしくは発電機の小型化を図るものである。   In Patent Document 2, two “propeller-type windmills” are arranged in series in the wind flow direction as “a wind turbine generator”. The wind turbine rotor at the front is attached to the rotor of the generator, and the rotor of the wind turbine at the rear is attached to the stator of the generator so that the rotor is rotatable. Rotating the generator's rotor and stator in different directions by using the rotation in the opposite direction, increasing the number of rotations, and generating power from the generator of the same scale from the proportional relationship between the generator's output and rotation speed The amount is increased or the generator is downsized.

しかしながら、上述の特許文献１に開示された発明においては、同文献により風車が風のエネルギーを出力に変換する変換率を３０％とすれば、風のエネルギーを１００として、変換量は第１の風車で３０、第１の風車の反転後流を受け逆転する第２の風車で２１、第２の風車の反転後流を受け第１の風車と同じ方向で回転する第３の風車で１４．７の計６５．７である。しかしながら、これら３個の風車で変換した風のエネルギーをトルクで発電機に伝えるには風車の回転方向、回転数に合わせた二重ないし三重の回転軸が必要となり、伝達機構は複雑になる。   However, in the invention disclosed in Patent Document 1 described above, if the conversion rate at which the windmill converts wind energy into output is 30% according to the same document, the wind energy is set to 100 and the conversion amount is the first. 30 in the windmill, 21 in the second windmill that receives and reverses the reverse flow of the first windmill, and 14 in the third windmill that receives the reverse flow of the second windmill and rotates in the same direction as the first windmill. That is a total of 65.7. However, in order to transmit the wind energy converted by these three windmills to the generator by torque, a double or triple rotation shaft according to the rotation direction and rotation speed of the windmill is required, and the transmission mechanism becomes complicated.

また、上述の特許文献２に開示された発明においては、風の流れ方向に直列に配置した二個のプロペラ型風車の後のロータが前の風車の反転後流で逆回転する関係を利用し、前部風車のロータを発電機の回転子に、後部風車のロータを回転可能とした発電機の固定子に取付け、発電機の回転子と固定子を異なる方向に回転させ回転数を増やし、回転速度と出力の比例関係から、同一規模の発電機の発電量を増やし、もしくは発電機の小型化を図るものであるが、発電機の固定子を回転させることにより発電機の機構は複雑となり、また、自然の風を駆動流体とする限り規模は大きくなり、稼動率は上がらない。   Further, in the invention disclosed in Patent Document 2 described above, a relationship is used in which the rotor behind the two propeller-type wind turbines arranged in series in the wind flow direction rotates in the reverse wake of the front wind turbine. The front wind turbine rotor is attached to the generator rotor, and the rear wind turbine rotor is attached to the generator stator which is rotatable, the generator rotor and stator are rotated in different directions to increase the number of revolutions, From the proportional relationship between the rotational speed and output, the power generation amount of the generator of the same scale is increased or the generator is reduced in size, but the generator mechanism becomes complicated by rotating the stator of the generator. In addition, as long as natural wind is used as the driving fluid, the scale increases and the operation rate does not increase.

本発明においては、常温常圧の空気を駆動流体に複数プロペラとプロペラ型風車でタービンを構成、個々プロペラの口径、回転数、ブレード枚数を調整し大きなエネルギーをもつ風をつくるとともに、少ない動力でプロペラを駆動し回転させる簡素な動力機構にすること、および風のもつ大きなエネルギーをトルクに変換し発電量に対応した出力にするためにプロペラ型風車のロータの口径、回転数、ブレード枚数を調整し、発電コストの低廉な発電方法とすることを課題とする。   In the present invention, a turbine is composed of a plurality of propellers and a propeller-type windmill using air at normal temperature and pressure as a driving fluid, and each individual propeller is adjusted in aperture, rotation speed, and number of blades to create a large energy wind and with less power. A simple power mechanism that drives and rotates the propeller, and adjusts the diameter, rotation speed, and number of blades of the rotor of the propeller type wind turbine in order to convert the large energy of the wind into torque and output corresponding to the amount of power generation However, an object is to provide a power generation method with low power generation cost.

本発明の請求項１に記載の低圧タービンによる発電方法は、第１の動翼のプロペラを駆動し回転させることにより流体である空気を吸引加速し風をつくる工程と、プロペラはそれを構成する複数のブレードの断面が回転軸を中心にラセン状に配置されており、回転によりブレード断面に設定された流体の流入角が位相し、前方からの加速流体が流入角に流入し回転すること、および流体が常温常圧の空気であればプロペラの回転でつくられる風はプロペラの直径、回転数、ブレード枚数に比例し、エネルギーの大きな風をつくるにはプロペラの直径を大きくし、回転数、ブレード枚数を増やせばよいことから、第１の動翼のプロペラで吸引加速された風の流れ方向に、間隔を置いて直列に配置した第１の動翼のプロペラより直径の大きな第２の動翼のプロペラに第１の動翼のプロペラで加速した風を吹込みプロペラを回転させる工程と、この回転方向に合わせ第２の動翼のプロペラを駆動し回転させることにより空気をさらに吸引加速し大きなエネルギーをもつ風とする工程と、第２の動翼のプロペラより直径の大きな第３の動翼のプロペラ型風車で、この大きなエネルギーの風を受けロータを回転させ風のエネルギーをトルクに変換、発電量に対応した出力にする工程と、このトルクで発電機を回転し発電をおこなう工程からなり、大きな風のエネルギーをトルクに変換、出力を調整し発電する作用を有している。   According to a first aspect of the present invention, there is provided a power generation method using a low-pressure turbine, wherein a step of driving and rotating a propeller of a first moving blade to suck and accelerate air as a fluid to generate wind, and the propeller constitutes the method. Cross sections of the plurality of blades are arranged in a spiral shape around the rotation axis, and the inflow angle of the fluid set in the blade cross section by rotation is in phase, and the acceleration fluid from the front flows into the inflow angle and rotates, If the fluid is air at normal temperature and normal pressure, the wind generated by the rotation of the propeller is proportional to the propeller diameter, rotation speed, and the number of blades. Since the number of blades may be increased, the second blade having a diameter larger than that of the first rotor blade propellers arranged in series at intervals in the direction of wind flow sucked and accelerated by the propeller of the first rotor blade. The step of rotating the propeller by blowing the wind accelerated by the propeller of the first blade into the propeller of the blade, and rotating the propeller of the second blade according to this rotation direction, further sucking and accelerating air This is the process of making the wind with a large energy and the propeller type wind turbine of the third rotor blade having a diameter larger than that of the propeller of the second rotor blade. By receiving this large energy wind, the rotor is rotated to turn the wind energy into torque. It has a process of converting and generating an output corresponding to the amount of power generation, and a process of generating power by rotating the generator with this torque, and has the function of converting large wind energy into torque and adjusting the output to generate power.

請求項２に記載の低圧タービンによる発電方法は、一般的にプロペラを回転させるには、プロペラを構成するブレード断面に流体である空気が流入する角度と直角に発生する揚力が、ブレード断面に流体が流入する角度の延長上に発生する抗力より大きくなるように回転軸から動力を与える方法による。この方法はプロペラを構成するブレード断面に空気が流入する角度に空気を吹込むに等しく、この角度への空気の吹込みによりプロペラは回転すること、また、プロペラの回転時のプロペラのブレード上の推力およびトルクの発生分布はブレード先端付近で高く、局所的に推力およびトルクの発生分布の高いブレード先端付近に空気を吹込むことにより、プロペラに回転軸から動力を与え空気を捲込み回転させる場合に比べ抗力は減少し、より少ない動力でプロペラが回転することは実験で確認される。したがって、第１の動翼のプロペラおよび第２の動翼のプロペラは、プロペラの回転により空気がプロペラを構成するブレード断面へ流入する角度で、局所的に推力およびトルクの発生分布の高いプロペラ先端付近に空気を吹込みプロペラを回転させる工程により、プロペラに回転軸から動力を与え回転させる場合に比べ少ない動力と複数のプロペラを回転軸で連結せず、もしくは多重の回転軸とすることなく、個々独立させることにより簡素な機構で大きなエネルギーをもつ風をつくりだす作用を有している。   In the power generation method using the low-pressure turbine according to claim 2, in general, in order to rotate the propeller, a lift force generated at right angles to an angle at which air as a fluid flows into the blade cross section constituting the propeller is generated in the blade cross section. This is based on a method in which power is applied from the rotating shaft so as to be larger than the drag generated on the extension of the angle at which the gas flows. This method is equivalent to blowing air at an angle at which air flows into the blade cross section constituting the propeller, and the propeller is rotated by blowing air at this angle, and the propeller blade is rotated on the propeller blade. The thrust and torque generation distribution is high near the blade tip. When air is blown locally near the blade tip where the thrust and torque generation distribution is high, the propeller is powered from the rotating shaft and the air is swept in. It is confirmed by experiments that the drag is reduced compared to, and the propeller rotates with less power. Accordingly, the propeller tip of the first blade and the propeller of the second blade have a propeller tip having a high distribution of thrust and torque locally at an angle at which air flows into the blade cross section constituting the propeller by the rotation of the propeller. By blowing air in the vicinity and rotating the propeller, the motive power from the rotating shaft to the propeller is rotated and less power and multiple propellers are not connected by the rotating shaft or multiple rotating shafts, By making them independent, they have a simple mechanism to create a wind with large energy.

請求項３に記載の低圧タービンによる発電装置は請求項１に記載の低圧タービンによる発電方法を発電装置として捉えたものであり、第１の動翼のプロペラからの風の流れ方向に直列に間隔をおいて配置した第１の動翼のプロペラより直径の大きな第２の動翼のプロペラと、第２の動翼のプロペラより直径の大きな第３の動翼のプロペラ型風車のロータと、これに連結した発電機で構成し、第１の動翼のプロペラおよび第２の動翼のプロペラで大きなエネルギーをもつ風を起し、この風を第３の動翼のプロペラ型風車に受けロータを回転させ、風のエネルギーをトルクに変換し出力を調整、発電機を稼動し発電をおこなうものであり、本請求項記載の発明の作用は請求項１の発明と同様である。   A power generation apparatus using a low-pressure turbine according to a third aspect captures the power generation method using the low-pressure turbine according to the first aspect as a power generation apparatus, and is spaced in series in the flow direction of the wind from the propeller of the first moving blade. A rotor of a second rotor blade having a diameter larger than the propeller of the first rotor blade disposed at a position, and a rotor of a propeller-type wind turbine of a third rotor blade having a diameter larger than the propeller of the second rotor blade, The first rotor blade propeller and the second rotor blade propeller generate a large amount of wind, and this wind is received by the third rotor blade propeller type windmill. Rotating, converting wind energy into torque, adjusting the output, operating the generator to generate power, and the operation of the present invention is the same as that of the first aspect.

請求項４に記載の低圧タービンによる発電装置は請求項２に記載の低圧タービンによる発電方法を発電装置として捉えたものであり、第１の動翼のプロペラおよび第２の動翼のプロペラについて、プロペラの回転により流体である空気がプロペラを構成するブレード断面へ流入する角度で、局所的に推力およびトルクの発生分布の高いプロペラ先端付近に空気を吹込みプロペラを回転させる手段を設け、少ない動力と簡素な機構でプロペラを回転させるものであり、本請求項記載の発明の作用は請求項２の発明と同様である。   A power generator using a low-pressure turbine according to a fourth aspect captures the power generation method using the low-pressure turbine according to claim 2 as a power generator, and the propeller of the first moving blade and the propeller of the second moving blade are: Providing a means to rotate the propeller by blowing air near the tip of the propeller where the thrust and torque generation distribution is locally high at the angle at which the fluid air flows into the blade cross-section that constitutes the propeller due to the rotation of the propeller. The propeller is rotated by a simple mechanism, and the action of the present invention is the same as that of the second aspect.

請求項５に記載の低圧タービンによる発電装置は、第１の動翼と第２の動翼の間を第２の動翼の口径と同じ口径の円筒形外殻を設けることにより、第１の動翼で加速された風と第２の動翼で吸引する流体である空気を偏流させず、また、第２の動翼の口径と第３の動翼の口径に合わせ拡大した円錐形の外殻で第２の動翼と第３の動翼の間の空間を密閉することにより風の拡散を防ぎ、風のエネルギーの式＝（１／２）×（空気密度）×（受風面積）×（風速）３から風のエネルギーをつくる大きな要素となる速い風速をつくる作用を有している。 The power generator using the low-pressure turbine according to claim 5 is provided with a cylindrical outer shell having the same diameter as that of the second moving blade between the first moving blade and the second moving blade. The air accelerated by the blades and the air that is the fluid sucked by the second blades do not drift, and the outside of the conical shape expanded to match the diameters of the second and third blades. Sealing the space between the second and third rotor blades with a shell prevents the wind from diffusing, and the wind energy formula = (1/2) × (air density) × (wind receiving area) X (Wind speed) It has the effect | action which produces the high wind speed which becomes a big element which produces the energy of a wind from 3 .

請求項６に記載低圧タービンによる発電装置は、第１の動翼、第２の動翼、第３の動翼の３個の回転機械により風速の早い風を利用するため騒音が発生、発電量が増えるにしたがい風となる空気の質量は増え騒音は大きくなる。したがって、第１の動翼と第２の動翼の間に設けた円筒形外殻の延長に吸気筒を設け、また、第２の動翼と第３の動翼の間の空間を密閉した円錐形外殻および発電機の外周を外殻で覆い、消音器をつけた複数の排気口を設けこの外殻の内部を常温常圧に近い状態にするとともに、発生騒音の外部漏出を防ぐ作用を有している。   The power generation apparatus using the low-pressure turbine according to claim 6 generates noise due to the use of wind having a high wind speed by the three rotating machines of the first moving blade, the second moving blade, and the third moving blade. As the value increases, the mass of air that becomes wind increases and the noise increases. Therefore, an intake cylinder is provided in the extension of the cylindrical outer shell provided between the first moving blade and the second moving blade, and the space between the second moving blade and the third moving blade is sealed. Covers the outer periphery of the conical outer shell and generator with the outer shell, and provides multiple exhaust ports with silencers to keep the inside of the outer shell close to normal temperature and normal pressure, and to prevent external leakage of generated noise have.

本発明は第１の動翼のプロペラの局所的に推力およびトルク発生分布の高いプロペラ先端付近に、流体である空気をプロペラを構成するブレード断面へ流入する角度に吹込み回転させ、周辺の空気を吸引加速し風を起し、この風をその流れ方向に直列に間隔を置き配置した第１の動翼のプロペラより直径の大きな第２の動翼のプロペラに吹込み回転させる。この回転方向に合わせ第２の動翼のプロペラを、第１の動翼のプロペラと同じ方法で回転させ、さらに空気を吸引加速することにより大きなエネルギーをもつ風とし、この風を第３の動翼のプロペラ型風車に吹込み、ロータを回転させ風のエネルギーをトルクに変換し出力を調整、発電機を稼動し発電をおこなう低圧タービンによる発電方法とその低圧タービンによる発電装置である。   The present invention blows and rotates air, which is a fluid, in the vicinity of the propeller tip where the thrust and torque generation distribution of the first rotor blade is locally high at an angle that flows into the blade cross section constituting the propeller. The air is sucked and accelerated to generate a wind, and this wind is blown into a propeller of a second moving blade having a diameter larger than that of the first moving blade propeller spaced in series in the flow direction. According to this rotational direction, the propeller of the second blade is rotated in the same manner as the propeller of the first blade, and air is sucked and accelerated to generate a large energy wind. A power generation method using a low-pressure turbine and a power generation device using the low-pressure turbine that blows into a propeller-type windmill of blades, rotates the rotor to convert wind energy into torque, adjusts the output, operates the generator, and generates power.

この方法による場合、空気速度は音速を限界とする。この制約のもとでプロペラの回転により発生する流体である空気の質量とプロペラの直径、回転数、ブレード枚数との関係は、回転数およびブレード枚数を一定としプロペラ直径をｎ倍にすれば空気の質量はｎ４倍、また、プロペラ直径およびブレード枚数を一定とし回転数をｎ倍にすれば空気の質量はｎ２倍、プロペラ直径および回転数を一定としブレード枚数をｎ倍にすれば空気の質量はｎ倍前後となる。 When this method is used, the speed of air is limited to the speed of sound. Under this restriction, the relationship between the mass of air, which is a fluid generated by the rotation of the propeller, the diameter of the propeller, the number of rotations, and the number of blades is constant if the number of rotations and the number of blades are constant and the propeller diameter is increased by n times. the mass n 4 times, also, the air if the rotational speed and the propeller diameter and number of blades is constant if n times the mass of air is n 2 times the propeller diameter and the rotational speed is constant number of blades n times The mass of is about n times.

この空気の質量とプロペラ回転用動力との関係は、第１の動翼のプロペラ先端付近で流体である空気をブレード断面へ流入する角度に吹込みプロペラを回転させ風を起し、この風を第１の動翼より直径の大きな第２の動翼のプロペラに吹付け回転させ、この回転方向に合わせ第２の動翼のプロペラを第１の動翼のプロペラと同じ方法で回転させることにより、プロペラの回転用動力は回転軸から動力を与え回転させる場合に比べ低減する。   The relationship between the air mass and propeller rotation power is that the air that is the fluid flows near the tip of the propeller of the first rotor blade at an angle at which the air flows into the blade cross section, and the propeller is rotated to generate wind. By spraying and rotating the propeller of the second blade having a larger diameter than the first blade, and rotating the propeller of the second blade in the same manner as the propeller of the first blade according to this rotation direction The power for rotating the propeller is reduced as compared with the case where the power is rotated from the rotating shaft.

プロペラ先端付近でブレード断面へ流入する角度に流体である空気を吹込む手段はブロアーである。プロペラ回転用動力はブロアーに要する電力であり発電機より自給する。ブロアーの稼動電力は吹込量と吹込圧によるが、ブレード断面へ空気が流入する角度はプロペラが空気を捲込む角度であり、プロペラの回転により吹込圧は低く、ブロアー稼動電力はプロペラ直径に対応する吹込量により、吹込圧は吹込量と吹込口径の関係で設定される。第２の動翼のプロペラの直径は第１の動翼のプロペラの直径より大きく、より大きな動力を必要とする。プロペラで加速された空気は収束し拡散する。したがって、第１の動翼のプロペラで加速した空気の拡散域を第２の動翼のプロペラの直径に準じた範囲に合わせプロペラ間隔を調整、第１の動翼のプロペラで加速した空気で第２の動翼のプロペラを回転させ、この回転方向に合わせ第２の動翼のプロペラを第１の動翼のプロペラと同じ方法で回転させることにより、第２の動翼のプロペラ回転用のブロアーの所要電力は低減し、ブロアーへの給電量の発電量に占める割合は低下する。   A means for blowing air, which is a fluid at an angle of flowing into the blade cross section near the tip of the propeller, is a blower. The power for propeller rotation is the power required for the blower and is supplied by the generator. The operating power of the blower depends on the blowing amount and the blowing pressure, but the angle at which air flows into the blade cross section is the angle at which the propeller inhales air. Depending on the blowing amount, the blowing pressure is set by the relationship between the blowing amount and the blowing diameter. The diameter of the propeller of the second blade is larger than the diameter of the propeller of the first blade and requires more power. The air accelerated by the propeller converges and diffuses. Therefore, the air diffusion area accelerated by the propeller of the first moving blade is adjusted to the range corresponding to the diameter of the propeller of the second moving blade, the propeller interval is adjusted, and the first airfoil accelerated by the propeller of the first moving blade is used. The second blade propeller is rotated, and the second blade propeller is rotated in the same manner as the first blade propeller according to the direction of rotation, thereby rotating the second blade propeller rotation blower. The required power is reduced, and the ratio of the amount of power supplied to the blower to the amount of power generation is reduced.

第１の動翼のプロペラと第２の動翼のプロペラで起した風のエネルギーは、空気の速度限界である音速に近いほど大きく、これに近い速度の風とする。このエネルギーをトルクに変換する第３の動翼のプロペラ型風車は、第２の動翼と第３の動翼の間の空間を円錐形の外殻で密閉していることから、第２の動翼のプロペラから吹込まれる空気の質量を一定とすれば、出力はプロペラ型風車のロータ直径で変化する。ロータ直径を第２の動翼のプロペラ直径相当に縮小すれば風速は速くなり、ロータの回転数も増え出力は大きくなるが、風のエネルギーを出力へ変換するロータのブレード枚数が増加する。ロータのブレード枚数には物理的な制約があり、この制約に適合するブレード枚数となるように第２の動翼のプロペラ直径より第３の動翼のプロペラ型風車のロータ直径を大きくし、このロータの直径で設定される風のエネルギーを出力に変換、発電をおこなう。   The energy of wind generated by the propellers of the first blade and the second blade is larger as it approaches the speed of sound, which is the velocity limit of air, and the wind speed is close to this. In the propeller type wind turbine of the third moving blade that converts this energy into torque, the space between the second moving blade and the third moving blade is sealed with a conical outer shell. If the mass of the air blown from the propeller of the rotor blade is constant, the output changes with the rotor diameter of the propeller type windmill. If the rotor diameter is reduced to a value equivalent to the propeller diameter of the second rotor blade, the wind speed increases, the rotor speed increases, and the output increases, but the number of blades of the rotor that converts wind energy into output increases. There is a physical restriction on the number of blades of the rotor. The rotor diameter of the propeller type wind turbine of the third blade is made larger than the diameter of the propeller of the second blade so that the number of blades conforms to this restriction. Wind energy set by the diameter of the rotor is converted into output to generate electricity.

プロペラ型風車に連結する発電機を商用周波数の交流発電機とすれば、回転数＝（１２０×周波数）／極数より、周波数６０Ｈｚ、極数４として回転数は１，８００rpm、この回転数にあわせ第２の動翼のプロペラから吹き込む空気の質量により第３の動翼のプロペラ型風車のロータ直径と変換する風のエネルギーを設定、これに見合う出力をロータのブレード枚数で調整する。一方、発電機の出力は回転数に比例し、同一出力で周波数を高め回転を早めれば規模は小さくなる。本発明の低圧タービンによる発電方法とその低圧タービンによる発電装置では、第１の動翼と第２の動翼の口径、回転数、ブレード枚数を調整、音速に近い速度の風とし、第３の動翼のロータのブレード枚数をその物理的な制約下、最大限に増やすことによりロータ直径を縮小、早い回転数とし小規模な発電機で大きな発電量とすることができる。但し、用途で周波数を変換する必要があり、発電量と装置製造費用で発電コストを調整する。   If the generator connected to the propeller-type wind turbine is an AC generator of commercial frequency, the rotation speed = (120 × frequency) / number of poles, the frequency is 60 Hz, the number of poles is 4, and the rotation speed is 1,800 rpm. In addition, the rotor energy of the propeller type wind turbine of the third rotor blade and the energy of the wind to be converted are set by the mass of air blown from the propeller of the second rotor blade, and the output corresponding to this is adjusted by the number of blades of the rotor. On the other hand, the output of the generator is proportional to the rotational speed, and the scale becomes smaller if the frequency is increased with the same output and the rotation is accelerated. In the power generation method using the low-pressure turbine and the power generation apparatus using the low-pressure turbine according to the present invention, the diameter, the rotation speed, and the number of blades of the first moving blade and the second moving blade are adjusted so that the wind speed is close to the speed of sound. By increasing the number of blades of the rotor blade as much as possible under the physical constraints, the rotor diameter can be reduced, the rotation speed can be increased, and a large amount of power can be generated with a small generator. However, it is necessary to convert the frequency depending on the application, and the power generation cost is adjusted by the power generation amount and the device manufacturing cost.
