In the current era of constantly adjusting the global energy landscape and deepening the concept of sustainable development, efficient and environmentally friendly energy conversion equipment has become a focus of attention. As a unique type of power generation equipment, gas generators have opened up a new path in the field of energy utilization with their excellent ability to efficiently convert gas into electricity. They are gradually emerging and providing reliable power support for multiple industries, while promoting energy utilization towards green and efficient directions. ​

工作原理：化学能到电能的高效转换​

Working principle: Efficient conversion of chemical energy to electrical energy

煤气发电机组的工作原理基于内燃机的基本运作机制，核心在于将煤气蕴含的化学能有序地转化为机械能，进而再转化为电能。当煤气被引入发动机的燃烧室时，与适量的空气混合形成可燃混合气。在发动机活塞下行的过程中，进气门打开，可燃混合气被吸入燃烧室。随后，活塞上行压缩混合气，当压缩冲程接近尾声时，火花塞产生电火花，点燃混合气。混合气迅速燃烧，释放出大量热能，使燃烧室内的气体温度和压力急剧升高，高温高压的气体推动活塞下行，通过连杆带动曲轴旋转，将化学能转化为机械能。​

The working principle of a gas generator set is based on the basic operating mechanism of an internal combustion engine, with the core being the orderly conversion of the chemical energy contained in the gas into mechanical energy, which is then converted into electrical energy. When gas is introduced into the combustion chamber of an engine, it mixes with an appropriate amount of air to form a combustible mixture. During the descent of the engine piston, the intake valve opens and the combustible mixture is drawn into the combustion chamber. Subsequently, the piston moves upward to compress the mixture. As the compression stroke approaches its end, the spark plug generates an electric spark, igniting the mixture. The mixture burns rapidly, releasing a large amount of heat energy, causing the temperature and pressure of the gas inside the combustion chamber to rise sharply. The high-temperature and high-pressure gas pushes the piston down, and through the connecting rod, drives the crankshaft to rotate, converting chemical energy into mechanical energy. ​

曲轴的旋转运动传递至发电机，发电机内部的转子在磁场中高速旋转，根据电磁感应原理，在定子绕组中产生感应电动势，从而输出电能。整个过程中，精确的控制系统对煤气的流量、空气与煤气的混合比例、点火时机等关键参数进行实时调节，以确保发动机始终处于最佳工作状态，实现化学能到电能的高效、稳定转换。例如，在一些大型煤气发电机组中，采用了先进的电子控制系统，通过传感器实时监测发动机的运行参数，如温度、压力、转速等，控制系统根据这些反馈信息，精确调节煤气供应阀和空气调节阀的开度，以及火花塞的点火提前角，使发动机在不同工况下都能保持良好的性能，发电效率可达 30% - 40%，有效提高了能源利用效率。​

The rotational motion of the crankshaft is transmitted to the generator, and the rotor inside the generator rotates at high speed in the magnetic field. According to the principle of electromagnetic induction, induced electromotive force is generated in the stator winding, thereby outputting electrical energy. Throughout the entire process, the precise control system adjusts key parameters such as gas flow rate, air to gas mixing ratio, ignition timing, etc. in real time to ensure that the engine is always in optimal working condition and achieve efficient and stable conversion of chemical energy to electrical energy. For example, in some large gas generator sets, advanced electronic control systems are used to monitor the operating parameters of the engine in real time through sensors, such as temperature, pressure, speed, etc. Based on these feedback information, the control system accurately adjusts the opening of the gas supply valve and air regulating valve, as well as the ignition advance angle of the spark plug, so that the engine can maintain good performance under different working conditions, and the power generation efficiency can reach 30% -40%, effectively improving energy utilization efficiency. ​

核心结构：协同运作的关键组件​

Core structure: key components for collaborative operation

煤气发电机组主要由煤气发动机、发电机、控制系统以及辅助设备等核心部件构成，各部件协同运作，保障机组稳定高效运行。​

The gas generator set is mainly composed of core components such as gas engine, generator, control system, and auxiliary equipment, which work together to ensure stable and efficient operation of the unit. ​

煤气发动机作为整个机组的动力源，其性能直接影响发电效率和稳定性。发动机的结构设计针对煤气燃烧特性进行优化，采用特殊的燃烧室形状和进气、排气系统，以促进煤气与空气的充分混合和高效燃烧。例如，一些发动机采用了预燃室设计，先在预燃室内点燃部分混合气，形成火焰核心，再喷入主燃烧室引发主燃烧，这种方式能够改善燃烧过程，降低燃烧噪声和排放。同时，发动机的活塞、连杆、曲轴等关键部件采用高强度、耐高温材料制造，以承受燃烧过程中的高温高压冲击，确保发动机长期可靠运行。​

As the power source of the entire unit, the performance of the gas engine directly affects the power generation efficiency and stability. The structural design of the engine is optimized for the combustion characteristics of gas, using special combustion chamber shapes and intake and exhaust systems to promote sufficient mixing and efficient combustion of gas and air. For example, some engines adopt a precombustion chamber design, where a portion of the mixture is ignited in the precombustion chamber to form a flame core, and then injected into the main combustion chamber to initiate main combustion. This method can improve the combustion process, reduce combustion noise and emissions. At the same time, key components such as pistons, connecting rods, and crankshafts of the engine are made of high-strength and high-temperature resistant materials to withstand the high temperature and high pressure impacts during combustion, ensuring long-term reliable operation of the engine. ​

发电机与煤气发动机通过联轴器刚性连接，将发动机输出的机械能转化为电能。发电机通常采用同步发电机，其定子绕组由高导磁率的硅钢片叠压而成，以减小铁芯损耗。转子则通过直流励磁产生磁场，在发动机带动下高速旋转，切割定子绕组的磁力线，产生稳定的交流电。为保证发电质量，发电机配备了电压调节器和频率控制器，能够根据负载变化自动调整励磁电流，稳定输出电压和频率，确保向用电设备提供高质量的电能。

The generator is rigidly connected to the gas engine through a coupling, converting the mechanical energy output by the engine into electrical energy. Synchronous generators are usually used, and their stator windings are made of stacked high permeability silicon steel sheets to reduce core losses. The rotor generates a magnetic field through direct current excitation and rotates at high speed under the drive of the engine, cutting the magnetic field lines of the stator winding and producing stable alternating current. To ensure the quality of power generation, the generator is equipped with a voltage regulator and a frequency controller, which can automatically adjust the excitation current according to load changes, stabilize the output voltage and frequency, and ensure the provision of high-quality electrical energy to electrical equipment.
