天然气联合循环电厂的噪声控制

Noise control of natural gas-fired combined cycle power plant

天然气联合循环电厂环保节能,大多安装在经济发达、人口稠密的大、中城市附近,但厂界噪声和周围声环境(主要是居民敏感点)的达标却成了极其突出的问题。本文介绍了厂界噪声和周围声环境的国家标准,以及用户如何对设备制造厂提出设备的噪声限值要求。并以浙江半山天然气联合循环发电工程为例,介绍了在联合循环发电工程建设中对主要噪声源的分析和治理措施,以及工程竣工验收后取得的噪声治理效果。

Natural gas - fired Combined cycle power plants protect environment and save energy. They are built in neighborhood of large or middie populous cities which have developed economy. But reaching the State Standard of bound noise and sound environment of circumference becomes an outstanding question. This paper introduces the State Standard of bound noise and sound environment of circumference, how customers require manufactories for limit noise of equipment. This paper introduces analyses and control measures of main noise sources in Hangzhou Banshan natural gas - fired combined cycle power plant. Satisfactory effect has been achieved on noise control through acceptance check of the project completion.
