燃气发电机组包含:发动机、发电机、控制器,还有可选用装置稳压过滤装置、气液(汽液)分离装置等,发动机与发电机同轴连接,并置于整机底盘上,再将消声器和调速器连接在发动机上,由燃气源通入发动机内的燃气通道,连接在发动机上带拉绳的反冲起动器以及连接在发电机输出端的电压调节器。其中燃气源内置放的可燃气体是天然气,或液化石油气,或沼气。使用燃气发电机组与汽油发电机组,柴油发电机组相比降低了对环境的污染,是一种环保节能型的发电机。而且结构简单,使用安全可靠,输出的电压和频率稳定。
The gas generator set includes: engine, generator, controller, as well as optional devices, pressure stabilizing filter device, gas-liquid (vapor-liquid) separation device, etc. the engine and the generator are coaxial connected and placed on the chassis of the whole machine. Then, the muffler and governor are connected to the engine. The gas source is connected to the gas channel in the engine and connected to the recoil starting with pull rope on the engine And a voltage regulator connected to the output terminal of the generator. Among them, the combustible gas put in the gas source is natural gas, liquefied petroleum gas, or biogas. Compared with gasoline generator set and diesel generator set, the use of gas generator set reduces the environmental pollution, which is an environmental protection and energy-saving generator. Moreover, the structure is simple, the use is safe and reliable, and the output voltage and frequency are stable.
燃气发电机组中燃气稳压过滤装置是燃气输配过程的主要和关键设备,主要承担调压和稳压的功能,同时还要承担过滤、计量、加臭、气体分配等一项或多项功能。

The gas pressure stabilizing and filtering device is the main and key equipment in the gas transmission and distribution process, which mainly undertakes the functions of pressure regulation and pressure stabilization, and also one or more functions of filtration, metering, odorization, gas distribution, etc.
过滤装置用于保护燃气管路的阀门,过滤网的孔径应不大于1.5MM。 如气阀列组配置独立稳压阀,其进气口前端应配置独立的过滤装置,避免堵塞稳压阀内的气管。
For the valve used to protect the gas pipeline, the aperture of the filter screen should not be greater than 1.5mm. If the gas valve train is equipped with independent pressure regulating valve, the front end of its air inlet shall be equipped with independent filtering device to avoid blocking the gas pipe in the pressure regulating valve.
稳压阀出口气压的波动在整个燃烧调节范围内应不超过±5%。
The fluctuation of pressure at the outlet of pressure stabilizing valve shall not exceed ± 5% in the whole combustion regulation range.
燃气轮机的工作过程是,压气机(即压缩机)连续地从大气中吸入空气并将其压缩;压缩后的空气进入燃烧室,与喷入的燃料混合后燃烧,成为高温燃气,随即流入燃气涡轮中膨胀做功,推动涡轮叶轮带着压气机叶轮一起旋转;加热后的高温燃气的做功能力显著提高,因而燃气涡轮在带动压气机的同时,尚有余功作为燃气轮机的输出机械功。燃气轮机由静止起动时,需用起动机带着旋转,待加速到能独立运行后,起动机才脱开。
The working process of a gas turbine is that the compressor (i.e. the compressor) continuously sucks air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel, and then becomes high-temperature gas, and then flows into the gas turbine to expand and work, so as to push the turbine impeller to rotate with the compressor impeller; the work capacity of the heated high-temperature gas is significantly improved Therefore, when the gas turbine drives the compressor, it still has surplus work as the output mechanical work of the gas turbine. When the gas turbine starts from standstill, the starter is required to rotate, and the starter will not be released until it can run independently.
燃气轮机的工作过程是更简单的,称为简单循环;此外,还有回热循环和复杂循环。燃气轮机的工质来自大气,又排至大气,是开式循环;此外,还有工质被封闭循环使用的闭式循环。燃气轮机与其他热机相结合的称为复合循环装置。
The working process of gas turbine is the simplest, called simple cycle; in addition, there are regenerative cycle and complex cycle. The working fluid of gas turbine comes from the atmosphere and finally discharges to the atmosphere, which is an open cycle; in addition, there is a closed cycle in which the working fluid is used in the closed cycle. The combination of gas turbine and other heat engines is called composite cycle device.
