Research of Noise Control Technique for Gas Power Plant

摘要：

According to the site sound intensity measurement, this article identified the main noise sources of the gas power generator which were combustion noise radiated through the cylinder cover and vent, and exhaust noise, and further analyzed the gas power generator noise spectrum. On this basis, a comprehensive gas power plant noise control program was put forward, including setting mobile semi-closed noise barriers, suspended absorbers, and impedance compound and dissipative expansion parallel combined exhaust muffler. The field test results showed that the treated gas power plant noise was reduced to the national standards, and the final effects were satisfying.
