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.
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.
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.
The fluctuation of pressure at the outlet of pressure stabilizing valve shall not exceed ± 5% in the whole combustion regulation range.
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.
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.
