燃气—蒸汽联合循环机组的噪声现状与控制措施

Noise Status and Control Measures of Gas-steam Combined Cycle Units

燃气轮机联合循环发电作为一种清洁、高效的发电形式,在国内得到了长足的发展。由于相对于燃煤火电其无粉尘污染、排放环保,因此,燃气轮机联合循环电厂的选址一般处于负荷中心及人口相对稠密的居民区。为了保障电厂周边居民的生活,尽可能减少噪音污染成为燃机联合循环电厂必须解决的问题。本文从实际电厂运行期间噪音数据入手,揭示了联合循环电厂的噪音现状,并结合噪音的产生机理及工程实际经验提供了噪音控制的指导性措施。

Gas turbine combined cycle power generation,as a clean and efficient form of power generation,has been greatly developed in China.Compared with coal-fired thermal power,it has no dust pollution and is environmentally friendly.Therefore,the site selection of gas turbine combined cycle power plants is generally located in load centers and relatively densely populated residential areas.In order to protect the lives of residents around the power plant,reducing noise pollution as much as possible has become a problem that must be solved in gas turbine combined cycle power plants.This article starts with the noise data during the actual power plant operation,reveals the noise status of the combined cycle power plant,and provides guidance measures for noise control in combination with the noise generation mechanism and engineering practical experience.
