瓦斯發電是一種以煤礦中瓦斯(煤層)氣體為燃燒物，代替汽油、柴油作為發動機動力的新型、高效的清潔能源發電，其主要核心設備為瓦斯燃氣發電機組。該發電機組具有輸出功率范圍廣、發電質量好、集成度高、維護簡單、運行可靠等優點。

　　Gas power generation is a new and efficient clean energy generation method that uses coal seam gas as combustion material, replacing gasoline and diesel as engine power. Its main core equipment is gas gas generator sets. This generator set has the advantages of wide output power range, good power generation quality, high integration, simple maintenance, and reliable operation.

　　在工程中各發電廠所使用的瓦斯發電機組品牌不同，有國內設備、也有國外設備，其功率大小也不盡相同，但從整個瓦斯發電工藝流程來看是一致的，其系統都是由進氣排氣系統、點火系統、潤滑系統、冷卻系統、綜合控制等系統構成。瓦斯電站布局示意圖煤層氣發電工程中都建有儲氣柜，保證燃機用氣的穩定。

　　The brands of gas generator sets used in various power plants in the project are different, including domestic and foreign equipment, and their power levels are also not the same. However, from the perspective of the entire gas power generation process, they are consistent, and their systems are composed of intake and exhaust systems, ignition systems, lubrication systems, cooling systems, comprehensive control systems, etc. Gas power station layout diagram: Gas storage tanks are built in coalbed methane power generation projects to ensure the stability of gas supply for gas turbines.

　　儲氣柜中的瓦斯氣體經過瓦斯氣預處理系統后，到達燃氣機組進入燃機混合器中，同時空氣經過空氣濾芯后同時進入混合器。在燃機混合器內，燃機對空氣和瓦斯氣進行自動配比后形成混合氣體，混合氣體經過渦輪增壓器后，再經過冷卻器進行兩級冷卻，使氣體溫度穩定在一定范圍內，通過不斷調整節氣閥，從而調整進氣量，最后進入氣缸內進行壓縮、做功，從而使發動機驅動發電機進行發電。瓦斯發電機組經做功排出的廢氣一般供給余熱鍋爐及其他換熱設備或直接排入大氣中。

　　The gas in the gas storage tank passes through the gas pre-treatment system and enters the gas turbine mixer. At the same time, the air passes through the air filter and enters the mixer. In the gas turbine mixer, the gas turbine automatically proportions air and gas to form a mixed gas. After passing through the turbocharger, the mixed gas is cooled in two stages by the cooler to stabilize the gas temperature within a certain range. By continuously adjusting the throttle valve, the intake air volume is adjusted, and finally it enters the cylinder for compression and work, so that the engine drives the generator to generate electricity. The exhaust gas discharged by the gas generator unit through work is generally supplied to the waste heat boiler and other heat exchange equipment or directly discharged into the atmosphere.

　　瓦斯發電機組主要由以下五大系統構成：

　　The gas generator set is mainly composed of the following five systems:

　　進氣排氣系統

　　Air intake and exhaust system

　　負責將瓦斯氣體與空氣按比例混合后送入發動機氣缸，同時排出燃燒后的廢氣。該系統包括空氣濾清器、瓦斯氣預處理裝置、混合器、渦輪增壓器、中冷器等部件，確保氣體供應穩定且符合燃燒要求。

　　Responsible for mixing gas with air in proportion and sending it into the engine cylinder, while discharging the exhaust gas after combustion. The system includes components such as air filters, gas pre-treatment devices, mixers, turbochargers, intercoolers, etc., to ensure stable gas supply and meet combustion requirements.

　　點火系統

　　ignition system

　　通過電子點火裝置在合適時機點燃混合氣體，使發動機正常工作。現代瓦斯發電機組多采用數字式點火技術，可根據發動機工況精確控制點火時間和能量，提高燃燒效率和穩定性。

　　Ignite the mixed gas at the appropriate time through an electronic ignition device to ensure normal engine operation. Modern gas generator sets often use digital ignition technology, which can accurately control ignition time and energy according to engine operating conditions, improving combustion efficiency and stability.

　　潤滑系統

　　lubrication system

　　為發動機的運動部件（如活塞、曲軸、軸承等）提供潤滑油，減少摩擦和磨損，保證發動機正常運轉。該系統包括機油泵、油道、機油濾清器、油底殼等部件，需定期檢查機油液位和質量。

　　Provide lubricating oil for the moving parts of the engine, such as pistons, crankshafts, bearings, etc., to reduce friction and wear and ensure the normal operation of the engine. The system includes components such as oil pump, oil passage, oil filter, and oil pan, which require regular inspection of oil level and quality.

　　冷卻系統

　　cooling system

　　防止發動機過熱，確保其在正常溫度范圍內工作。通常采用水冷或風冷方式，通過冷卻液循環或風扇散熱，將發動機產生的熱量散發出去。冷卻系統包括膨脹水箱、水泵、散熱器、冷卻管道等部件。

　　Prevent engine overheating and ensure it operates within the normal temperature range. Usually, water or air cooling is used to dissipate the heat generated by the engine through coolant circulation or fan cooling. The cooling system includes components such as expansion tank, water pump, radiator, cooling pipeline, etc.

　　綜合控制系統

　　Integrated control system

　　對發電機組的整體運行進行監測、控制和管理，包括電子管理系統（TEM）、自動電壓調節器（AVR）、保護裝置等。該系統可實時監測發動機的轉速、溫度、壓力、電壓等參數，實現自動啟停、負荷調節、故障診斷和保護等功能，確保機組安全穩定運行。

　　Monitor, control, and manage the overall operation of the generator set, including electronic management system (TEM), automatic voltage regulator (AVR), protective devices, etc. This system can monitor the engine's speed, temperature, pressure, voltage and other parameters in real time, achieve automatic start stop, load adjustment, fault diagnosis and protection functions, and ensure the safe and stable operation of the unit.

　　這些系統相互配合，共同保障瓦斯發電機組的正常運行和高效發電。

　　These systems work together to ensure the normal operation and efficient power generation of gas generators.
