本発明は吸入側にガス燃焼室を取り付けたガス
燃焼膨張機を使用するパツケージ型の発電装置に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a package-type power generation device using a gas combustion expander having a gas combustion chamber attached to the suction side.
「従来の技術及びその問題点」

域、数百KWを小型分野と区分される。"Conventional technology and its problems" In recent years, the use of power generation equipment using combustion expanders using gas turbines has expanded from large to medium-sized to small-sized. , a few hundred KW is classified as a small field.
そして中型領域から小型領域に使用する発電装

発電装置と一体化させる事は出来ず、一般には別
室に防爆室を設けて設置され、而も駆動用電動機
として防爆型電動機を使用せねばならなかつた。 On the other hand, since the gas sent to the combustion chamber attached to the suction side of the gas turbine combustion expander needs to be pressurized once, a fuel gas compressor is used to compress the gas supplied to the combustion chamber. Since the compressor is installed separately and driven by an electric motor, it cannot be integrated with the generator, and is generally installed in a separate explosion-proof room, and the drive electric motor is explosion-proof. I had to use an electric motor.
従つて中型、小型発電装置においても全体装置
をパツケージ化出来ないこと、スペースが分離し
て防爆設備が必要である事、設備費用の増加にな
る事等の種々の問題があつた。 Therefore, even in medium-sized and small-sized power generators, there are various problems such as the inability to package the entire device, the need for explosion-proof equipment due to separate spaces, and increased equipment costs.
本発明はかかる従来技術の欠点に鑑み、電動機

ケージ化することを目的とするものである。 In view of the drawbacks of the prior art, it is an object of the present invention to integrally package the entire gas expander power generation device by driving the fuel gas compressor without using an electric motor.

容した点を第１の特徴とする。"Means for Solving the Problems" The present invention provides a gas combustion expander comprising a screw type expander or a gas turbine, a screw type air compressor supplying air to the combustion chamber, and a generator comprising an induction motor. and a screw-type fuel gas compressor for pressurizing the fuel gas supplied to the gas combustion chamber, and the first feature is that these are integrally housed in a package.

される。"Operation" According to this technical means, a fuel gas compressor that boosts the pressure of the fuel gas supplied to the gas combustion chamber is connected to the output shaft side of the generator driven by the gas combustion expander. The fuel gas compressor can be driven without using an electric motor, which eliminates the need to separately install the fuel gas compressor with an independent motor. Since no consideration is required, the entire power generation device can be integrated into one package, and soundproofing and compactness can be easily achieved.

動の吸収の容易なスクリユー型圧縮機を用いたが
故にガス燃焼膨張機側で負荷変動によつても円滑
に駆動させる事が出来る。 In addition, the gas combustion expander, which functions as a driving source, cannot necessarily keep its driving energy constant because the amount of combustion gas supplied to the combustion chamber fluctuates, but the fuel gas compressor, which is driven via a generator, also has a load. Since a screw type compressor is used that can easily absorb fluctuations, the gas combustion expander can be driven smoothly even with load fluctuations.
この場合前記ガス燃焼膨張機は変速機に直接連
結してもよく、又ガス燃焼膨張機と変速機との間
に空気圧縮機を介在させて連結してもよい。 In this case, the gas combustion expander may be directly connected to the transmission, or an air compressor may be interposed between the gas combustion expander and the transmission.

パツケージ化の容易化と熱効率の向上を図る事が
可能となる。 Incidentally, by using a screw-type gas expander as the gas combustion expander, it is possible to easily cope with fluctuations in the supply amount from the combustion chamber, and the air compressor forming a part of the gas combustion expander can also be used as the gas combustion expander. By using a screw type compressor coaxially connected to the expander, it is possible to simplify packaging and improve thermal efficiency.

層円滑な起動が容易になる。 Further, by using an induction motor as the generator, when the gas combustion expander is started, the induction motor is rotated using a commercial power source and the rotational force is transmitted to the gas combustion expander. Air compressors and other special starters are no longer required, resulting in smaller equipment, lower installation costs, and lower operating costs.
This makes it possible to simplify the configuration. In this case, by using an induction motor that can be controlled by an inverter as the generator, the rotational speed etc. can be freely changed, and smoother startup becomes easier.

の分安定する。 In addition, because the combustion compressor is not directly connected to the gas combustion expander (via a transmission), but is connected via a generator, it is possible to effectively drive the generator that requires the most driving energy, and it is possible to effectively drive the generator, which requires the most drive energy. Since the fuel gas compressor can be driven by a heavy force, the amount of fuel gas necessary for driving the generator can be reliably supplied to the expander side, and the driving of the generator can be stabilized accordingly.
