Basic structure:

燃气发电机组由燃气系统、发动机系统和发电机系统三部分组成。

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

燃气系统

Gas system

燃气系统包括气体源、气体调节、气体过滤、气体控制等设备，用于将燃气输送到发动机中进行燃烧。

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.

发动机系统

Engine system

发动机系统由发动机和其它辅助设备组成，发动机是燃气发电机组的核心部件，它将燃气燃烧产生的高温高压气体转化为机械能，通过曲轴传递给发电机。

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.

发电机系统

Generator system

发电机系统主要由发电机和其它配套设备组成，用于将发动机输出的机械能转化为电能，并通过输出电缆输送到电网或负载。

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:

气进入发动机

Gas enters the engine

燃气发电机组的燃气从储气罐、天然气管道或煤矿瓦斯管道等燃气来源处进入发动机，进气阀门控制气体的流量。

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.

压缩空气

compressed air

进入发动机的燃气与压缩空气混合后，由活塞压缩，使气体的温度和压力都升高。

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.

燃气燃烧

combustion of gases

混合后的气体进入燃烧室，通过点火器点燃，燃烧产生高温高压气体，使活塞向下运动，推动曲轴转动。

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.

曲轴转动

Crankshaft rotation

由于活塞的运动，曲轴开始转动，将机械能传递给发电机。

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

电能输出

Electric energy output

发电机将机械能转化为电能，输出给电网或负载使用，完成发电任务。

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，燃气发电机组的燃气燃烧产生的废气需要经过处理后排放，以避免对环境造成污染。此外，燃气发电机组还需要定期维护保养，以使其正常运行和延长使用时间。

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.
