燃氣發電機組由燃氣系統、發動機系統和發電機系統三部分組成。

The gas generator set consists of three parts: gas system, engine system, and generator system.

燃氣系統

Gas system

燃氣系統包括氣體源、氣體調節、氣體過濾、氣體控制等設備，用于將燃氣輸送到發動機中進行燃燒。

The gas system includes equipment such as gas source, gas regulation, gas filtration, and gas control, which are used to deliver gas to the engine for combustion.

發動機系統

Engine system

發動機系統由發動機和其它輔助設備組成，發動機是燃氣發電機組的核心部件，它將燃氣燃燒產生的高溫高壓氣體轉化為機械能，通過曲軸傳遞給發電機。

The engine system consists of an engine and other auxiliary equipment. The engine is the core component of a gas generator set, which converts the high-temperature and high-pressure gas generated by gas combustion into mechanical energy, which is transmitted to the generator through the crankshaft.

發電機系統

Generator system

發電機系統主要由發電機和其它配套設備組成，用于將發動機輸出的機械能轉化為電能，并通過輸出電纜輸送到電網或負載。

The generator system mainly consists of a generator and other supporting equipment, which is used to convert the mechanical energy output by the engine into electrical energy and transmit it to the power grid or load through output cables.

工作原理：

Working principle:

氣進入發動機

Gas enters the engine

燃氣發電機組的燃氣從儲氣罐、天然氣管道或煤礦瓦斯管道等燃氣來源處進入發動機，進氣閥門控制氣體的流量。

The gas from the gas generator set enters the engine from sources such as gas storage tanks, natural gas pipelines, or coal mine gas pipelines, and the intake valve controls the gas flow rate.

壓縮空氣

compressed air

進入發動機的燃氣與壓縮空氣混合后，由活塞壓縮，使氣體的溫度和壓力都升高。

After the gas entering the engine is mixed with compressed air, it is compressed by the piston, causing the temperature and pressure of the gas to increase.

燃氣燃燒

combustion of gases

混合后的氣體進入燃燒室，通過點火器點燃，燃燒產生高溫高壓氣體，使活塞向下運動，推動曲軸轉動。

The mixed gas enters the combustion chamber and is ignited by the igniter, producing high-temperature and high-pressure gas that causes the piston to move downward and drives the crankshaft to rotate.

曲軸轉動

Crankshaft rotation

由于活塞的運動，曲軸開始轉動，將機械能傳遞給發電機。

Due to the movement of the piston, the crankshaft begins to rotate, transmitting mechanical energy to the generator.

電能輸出

Electric energy output

發電機將機械能轉化為電能，輸出給電網或負載使用，完成發電任務。

The generator converts mechanical energy into electrical energy and outputs it to the power grid or load to complete the power generation task.

需要注意的是，燃氣發電機組的燃氣燃燒產生的廢氣需要經過處理后排放，以避免對環境造成污染。此外，燃氣發電機組還需要定期維護保養，以使其正常運行和延長使用時間。

It should be noted that the exhaust gas generated by the combustion of gas in gas generators needs to be treated and discharged to avoid environmental pollution. In addition, gas generator sets also require regular maintenance to ensure their normal operation and extend their service life.
