Description
本發明涉及一種燃氣渦輪機模組,尤指一種可增加燃燒效率的燃氣渦輪機模組。The invention relates to a gas turbine module, in particular to a gas turbine module capable of increasing combustion efficiency.
一般油電混合動力車(Hybrid electric vehicle 簡稱HEV)使用內燃機及電動機作為動力來源,其中內燃機是將液體燃料或是氣體燃料與空氣混合後,直接輸入機器內部產生熱能再轉化為機械能的一種熱機,內燃機具有體積小、質量小、便於移動、熱效率高、起動性能好的特點。目前運用在車輛的燃氣渦輪機是屬於熱機的一種發動機,其主要包括有壓縮機、燃燒室、渦輪等部分,首先由壓縮機將通過進氣口進入的新鮮空氣加壓成為高壓氣體,接著通過噴油嘴噴出燃油與高壓氣體混合,進入燃燒室燃燒形成高溫高壓氣體,然後以該高溫高壓氣體推動渦輪,將熱能轉換為機械能輸出,最後廢氣則由排氣口排出於大氣之中。這些自燃氣渦輪機排出的廢氣通常仍然屬於高溫高壓的氣體,排除於大氣之中形成另一種能源的浪費,因此仍然有被回收再利用。例如;復熱式循環燃氣渦輪機以渦卷器(Scroll)、收集器(Collector)以及引氣道等,收集渦輪排出的高溫廢氣使進入燃燒室的高壓氣體溫度增高,可以提昇機組的熱效率並減少燃料的消耗量。但是,復熱式循環燃氣渦輪機只是利用高溫高壓廢氣中的熱能部分,對於仍然存在於廢氣中的壓力能尚未有效運用。A Hybrid electric vehicle (HEV) uses an internal combustion engine and an electric motor as a power source. The internal combustion engine is a heat engine that directly mixes liquid fuel or gaseous fuel with air and directly inputs heat into the machine to convert it into mechanical energy. The internal combustion engine has the characteristics of small volume, small mass, easy movement, high thermal efficiency and good starting performance. The gas turbine currently used in a vehicle is an engine of a heat engine, and mainly includes a compressor, a combustion chamber, a turbine and the like. First, the compressor pressurizes fresh air entering through the intake port into a high-pressure gas, and then passes through The fuel injected from the injector mixes with the high-pressure gas, enters the combustion chamber to form a high-temperature and high-pressure gas, and then drives the turbine with the high-temperature and high-pressure gas to convert the thermal energy into mechanical energy output, and finally the exhaust gas is discharged into the atmosphere through the exhaust port. These exhaust gases from gas turbines are still still high-temperature and high-pressure gases, which are excluded from the atmosphere and form another source of energy waste, so they are still recycled. For example, a regenerative cycle gas turbine collects high-temperature exhaust gas from a turbine with a scroll, a collector, and an air intake to increase the temperature of the high-pressure gas entering the combustion chamber, thereby improving the thermal efficiency of the unit and reducing Fuel consumption. However, the reheat cycle gas turbine only utilizes the portion of the heat energy in the high temperature and high pressure exhaust gas, and the pressure energy still present in the exhaust gas has not been effectively utilized.
有鑒於此,有必要提供可增加進氣壓力提升燃燒效率的一種燃氣渦輪機模組。In view of this, it is necessary to provide a gas turbine module that can increase the intake pressure and improve the combustion efficiency.
本發明提供一種燃氣渦輪機模組,其包括一燃氣渦輪以及一渦輪機。該燃氣渦輪包括一進氣口、一壓縮機、一燃燒室、一渦輪轉子以及一排氣口。該進氣口位於該壓縮機的前端,該壓縮機的後方設置該燃燒室,該燃燒室與該排氣口之間設置該渦輪轉子。該排氣口與該進氣口之間設置該渦輪機,該渦輪機具有同軸設置的一第一渦輪轉子及一第二渦輪轉子。The present invention provides a gas turbine module that includes a gas turbine and a turbine. The gas turbine includes an air inlet, a compressor, a combustion chamber, a turbine rotor, and an exhaust port. The air inlet is located at a front end of the compressor, and the combustion chamber is disposed behind the compressor, and the turbine rotor is disposed between the combustion chamber and the exhaust port. The turbine is disposed between the exhaust port and the intake port, and the turbine has a first turbine rotor and a second turbine rotor disposed coaxially.
相較現有技術,本發明的燃氣渦輪機模組,通過在該排氣口與該進氣口之間設置的該渦輪機,使該燃氣渦輪運作所排出的廢氣流可驅動該渦輪機在該排氣口設置具有的該第一渦輪轉子旋轉,該渦輪轉子同軸設置的該第二渦輪轉子將隨著一併旋轉,而該第二渦輪轉子位於該進氣口處,可對該壓縮機的進氣增壓,提高該燃燒室的進氣量與進氣壓力,從而可以有效提高該燃氣渦輪機的燃燒效率。Compared with the prior art, the gas turbine module of the present invention, through the turbine disposed between the exhaust port and the intake port, allows the exhaust gas flow discharged by the gas turbine to drive the turbine in the row The air port is provided with the rotation of the first turbine rotor, the second turbine rotor coaxially disposed on the turbine rotor will rotate together, and the second turbine rotor is located at the air inlet, and the compressor can be advanced The air pressure is increased to increase the intake air amount and the intake air pressure of the combustion chamber, so that the combustion efficiency of the gas turbine can be effectively improved.
下面將結合附圖對本發明作一個具體介紹。The present invention will be specifically described below with reference to the accompanying drawings.
請參閱圖1所示,為本發明燃氣渦輪機模組實施例的氣體流動示意圖,該渦輪機模組10,包括一燃氣渦輪12以及一渦輪機14。本實施例該燃氣渦輪12為復熱式循環燃氣渦輪機,該燃氣渦輪12除了包括一壓縮機122、一燃燒室124、一渦輪轉子126以外更具有一熱交換器128。該壓縮機122產生的高壓氣體首先會經過該熱交換器128,使該高壓氣體的溫度提高後再送進該燃燒室124,該燃燒室124以該增溫的高壓氣體混合燃料後,燃燒生成的高溫高壓氣體則驅動該渦輪轉子126,用以使熱能轉化為機械能對外界作功。例如,以該渦輪轉子126驅動一發電機20,使該發電機20對油電混合動力車的電力驅動馬達的電池(圖中未標示)提供電力,或是使該渦輪轉子126直接驅動油電混合動力車的傳動系統以提供燃料驅動的動力,當然該渦輪轉子126也可以同時軸向帶動該壓縮機122對空氣進行加壓。驅動該渦輪轉子126後的廢氣仍然具有高溫高壓,因此可以回收導引至該熱交換器128內,以該廢氣的高溫對該壓縮機122產生的高壓氣體進行熱交換,使該壓縮機122產生的高壓氣體溫度提高,從而提高該氣體進入該燃燒室124的燃燒效率。通過該熱交換器128的該廢氣雖然經過熱交換而降溫但是仍然具有壓力,因而可以導引至該渦輪機14處,藉由該廢氣的壓力提供驅動該渦輪機14的動力,使該渦輪機14對該壓縮機122的進氣進行增壓。該渦輪機14的增壓運作將使更多的氣體同時進入該壓縮機122,並使該壓縮機122進入該燃燒室124的壓力更大,從而更多的空氣以及更高的壓力在該燃燒室124燃爆,將可更加提昇該燃氣渦輪12對外輸出的動力。該燃氣渦輪12也可以是單段式燃氣渦輪機,該單段式燃氣渦輪機不具有該熱交換器128設置,該壓縮機122產生的高壓氣體直接進入該燃燒室124,該燃燒室124爆燃產生的高溫高壓氣體驅動該渦輪轉子126後的廢氣就導向該渦輪機14,用以驅動該渦輪機14對該壓縮機122的進氣進行增壓。Please refer to FIG. 1 , which is a schematic diagram of gas flow of an embodiment of a gas turbine module according to the present invention. The turbine module 10 includes a gas turbine 12 and a turbine 14 . In this embodiment, the gas turbine 12 is a reheating cycle gas turbine. The gas turbine 12 further includes a heat exchanger 128 in addition to a compressor 122, a combustion chamber 124, and a turbine rotor 126. The high-pressure gas generated by the compressor 122 first passes through the heat exchanger 128, and the temperature of the high-pressure gas is increased and then sent to the combustion chamber 124. The combustion chamber 124 is mixed with the warmed high-pressure gas and then burned. The high temperature and high pressure gas drives the turbine rotor 126 to convert thermal energy into mechanical energy to work on the outside. For example, the generator rotor 20 is driven by the turbine rotor 126 to provide power to the battery (not shown) of the electric drive motor of the hybrid electric vehicle, or to directly drive the turbine rotor 126. The drive train of the hybrid vehicle provides fuel-driven power. Of course, the turbine rotor 126 can also axially drive the compressor 122 to pressurize the air. The exhaust gas after driving the turbine rotor 126 still has a high temperature and a high pressure, so that it can be recovered and guided into the heat exchanger 128, and the high pressure gas generated by the compressor 122 is heat exchanged at a high temperature of the exhaust gas, so that the compressor 122 is generated. The high pressure gas temperature is increased to increase the combustion efficiency of the gas entering the combustion chamber 124. The exhaust gas passing through the heat exchanger 128, although cooled by heat exchange, still has pressure and can be directed to the turbine 14, by which the pressure of the exhaust gas provides power to drive the turbine 14, causing the turbine 14 to The intake air of the compressor 122 is pressurized. The boosting operation of the turbine 14 will cause more gas to enter the compressor 122 at the same time, and the compressor 122 will enter the combustion chamber 124 at a higher pressure, thereby providing more air and higher pressure in the combustion chamber. 124 blasting will further enhance the external output of the gas turbine 12. The gas turbine 12 can also be a single-stage gas turbine that does not have the heat exchanger 128 disposed, the high pressure gas produced by the compressor 122 directly entering the combustion chamber 124, the combustion chamber 124 The high temperature and high pressure gas generated by the deflagration drives the exhaust gas after the turbine rotor 126 is directed to the turbine 14 for driving the turbine 14 to pressurize the intake air of the compressor 122.
