Cadna/A软件用于大型双曲线自然通风冷却塔噪声预测的适用性分析

大型双曲线自然通风冷却塔是火电厂和内陆核电厂主要的噪声源之一,采用合适的噪声预测软件对该类型冷却塔的噪声影响进行预测分析,对开展火电厂和内陆核电厂噪声评价工作具有重要意义。选取运行的大型双曲线自然通风冷却塔为研究对象,通过对噪声预测值和实测值的对比分析,验证Cadna/A软件在该类型冷却塔噪声预测的准确性,结果表明采用Cadna/A软件对大型双曲线自然通风冷却塔进行噪声预测是合适的。

Application Analysis of Cadna/A for Predicting Noise Produced by Large-scale Hyperbolic Natural Draft Cooling Tower

The large-scale hyperbolic natural draft cooling tower is one of the major noise sources in both coal-fired power plants and in-land nuclear power plants. Thus it is extremely important for the noise assessment in coal-fired power plants and in-land nuclear power plant that appropriate noise prediction software is selected to analyze the effect of noise generated in this sort of cooling tower. In this paper an operating large-scale hyperbolic natural draft cooling tower is chosen as the study model. Through the comparison between the predicted and the measured results, the accuracy of Cadna/A software to predict the noise produced in this type of cooling tower is validated. It can be concluded that the noise prediction results obtained by Cadna/A for the large-scale hyperbolic natural draft cooling tower is available.
