大型天然气联合循环电厂噪声的综合治理

Noise Comprehensive Control of Large-scale Natural Gas-fired Combined Cycle Power Plant

天然气联合循环电厂环保节能,大多建在经济发达、人口稠密的大中型城市附近,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。通过对浙江半山天然气联合循环发电工程的分析,对主厂房、余热锅炉、冷却塔等主要噪声源治理提出方案,治理工程通过竣工验收,证明取得了良好的治理效果。

Natural gas-fired combined cycle power plants protect environment and save energy. They are of large or middle 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 analysis and control measures of main noise sources in Hangzhou Banshan natural gas-fired combined cycle power plant. Satisfactory effect on noise control has been achieved through acceptance check of the project completion.
