| 中文摘要: |
| 天然气热电联产项目因其高效、环保、占地面积小、耗水少及建设周期短等优点而受到各国的广泛关注,但燃气电站噪声污染问题较为突出,通过声学照相机识别厂区内的噪声源,确定厂界的噪声值,对噪声源声学特性进行分析,建立噪声源及建筑的声学模型并进行仿真计算,确定噪声源对项目边界的影响并提出声学设计方案,对最终方案实施后的效果进行实测。结果表明该方案满足了声环境要求,可供同类大型燃气电厂的噪声控制项目参考。 |
| 英文摘要: |
| Combined cycle power plant has got widespread attention by many countries because of the advantages in efficiency, environmental protection, water saving, limited area and short construction period. But the noise pollution is a prominent problem for gas turbine power plant. This paper gives a brief introduction of the noise sources and noise levels in the plant boundaries identified by an acoustic camera. Also, the characteristics of the noise sources are analyzed and the acoustic models of noise sources are established for simulation. The acoustic influences of the noise sources on the test points in the plant boundary are calculated and the corresponding acoustic solutions are designed according to the calculation. The final result of the design has been checked through tests and shows that the acoustic specification for environmental protection is achieved. This discussion could be a reference of noise control project for similar gas-steam combined cycle power plant. |
