在全球能源轉型的浪潮中，燃氣發電機組憑借高效環保的特性，成為分布式能源系統的重要組成部分。從城市應急供電到工業余熱利用，從偏遠地區電力保障到調峰電源建設，燃氣發電機組正以靈活多樣的應用場景，為構建新型電力系統提供關鍵支撐。

In the wave of global energy transformation, gas-fired generators have become an important component of distributed energy systems due to their high efficiency and environmental friendliness. From emergency power supply in cities to industrial waste heat utilization, from power guarantee in remote areas to peak shaving power supply construction, gas-fired generator sets are providing key support for building new power systems with flexible and diverse application scenarios.

一、工作原理：燃料到電力的高效轉化

1、 Working principle: Efficient conversion of fuel to electricity

燃氣發電機組的核心是將燃料化學能轉化為電能的能量轉換系統。其工作流程可分為四步：

The core of a gas-fired generator set is an energy conversion system that converts fuel chemical energy into electrical energy. The workflow can be divided into four steps:

燃料供給：天然氣、沼氣等燃料經調壓系統進入燃燒室

Fuel supply: Natural gas, biogas and other fuels enter the combustion chamber through a pressure regulating system

燃燒膨脹：燃料與空氣混合燃燒，產生高溫高壓氣體

Combustion expansion: The mixture of fuel and air is burned to produce high-temperature and high-pressure gas

動力轉換：氣體推動渦輪葉片旋轉，驅動發電機發電

Power conversion: Gas drives turbine blades to rotate, driving a generator to generate electricity

余熱回收：通過余熱鍋爐回收尾氣熱量，實現熱電聯產

Waste heat recovery: Recovering exhaust heat through waste heat boilers to achieve cogeneration of heat and power

以某 10MW 天然氣發電機組為例，其發電效率可達 42%，若搭配余熱回收系統，綜合能源利用率可提升至 85% 以上。

Taking a 10MW natural gas generator set as an example, its power generation efficiency can reach 42%. If equipped with a waste heat recovery system, the comprehensive energy utilization rate can be increased to over 85%.

二、技術優勢：多維度領先特性

2、 Technical advantage: Multi dimensional leading characteristics

1. 環保性能突出

1. Outstanding environmental performance

氮氧化物排放低于 50mg/m?（國家標準為 200mg/m?）

Nitrogen oxide emissions below 50mg/m? (The national standard is 200mg/m?)

二氧化碳排放量較燃煤機組減少 40%

Reduce carbon dioxide emissions by 40% compared to coal-fired units

某數據中心采用燃氣三聯供系統，年減排二氧化碳 1.2 萬噸

A certain data center adopts a gas triple supply system, reducing carbon dioxide emissions by 12000 tons annually

2. 運行靈活高效

2. Flexible and efficient operation

啟動時間短：從冷態到滿負荷僅需 15 分鐘

Short startup time: It only takes 15 minutes from cold state to full load

負荷調節范圍廣：可在 30%-100% 負荷區間穩定運行

Wide load regulation range: can operate stably in the 30% -100% load range

部分負荷效率高：50% 負荷時效率仍保持在 38% 以上

Partial load efficiency is high: the efficiency remains above 38% at 50% load

3. 燃料適應性強

3. Strong fuel adaptability

可使用天然氣、煤層氣、焦爐煤氣等多種氣源

Can use various gas sources such as natural gas, coalbed methane, coke oven gas, etc

某垃圾填埋場利用沼氣發電，年處理廢氣 300 萬立方米

A certain landfill uses biogas to generate electricity and processes 3 million cubic meters of waste gas annually

三、應用場景：多樣化需求解決方案

3、 Application scenario: Diversified demand solutions

1. 分布式能源系統

1. Distributed energy system

在工業園區建設燃氣分布式能源站，同時提供電力、蒸汽和制冷，綜合能效提升 30%。例如蘇州某科技園區項目，年節約標煤 2.1 萬噸。

Constructing gas distributed energy stations in industrial parks, while providing electricity, steam, and refrigeration, can improve overall energy efficiency by 30%. For example, a technology park project in Suzhou saves approximately 21000 tons of standard coal annually.

2. 備用電源保障

2. Backup power supply guarantee

金融機構、醫院等重要場所配置燃氣發電機組，確保市電中斷時的持續供電。某銀行數據中心應用案例顯示，系統切換時間小于 0.1 秒。

Financial institutions, hospitals, and other important places are equipped with gas generators to ensure continuous power supply in the event of a power outage. The application case of a certain bank's data center shows that the system switching time is less than 0.1 seconds.

3. 調峰電源建設

3. Construction of peak shaving power supply

在電網負荷波動較大地區，燃氣機組可快速響應負荷變化。廣東某調峰電廠配置 4 臺 300MW 燃氣機組，年調峰能力達 1200 小時。

In areas with significant fluctuations in power grid load, gas turbines can quickly respond to load changes. A peak shaving power plant in Guangdong is equipped with four 300MW gas-fired units, with an annual peak shaving capacity of 1200 hours.

4. 偏遠地區供電

4. Power supply in remote areas

在無電網覆蓋的海島、礦區，燃氣機組可獨立供電。某海上鉆井平臺使用燃氣發電，滿足 500 人生活及設備用電需求。

In islands and mining areas without power grid coverage, gas turbines can provide independent power supply. A certain offshore drilling platform uses gas power generation to meet the electricity needs of 500 people's daily lives and equipment.
