摘要:

某燃气电厂的立式余热锅炉噪声大,低频噪声突出,且由于布局较紧凑,常规的整体隔声围护措施无法实施。针对该类型锅炉的低频噪声进行了研究,辨识其来源,并根据分析结果,研发了新的降噪装置在实际中应用。应用结果表明,该装置能够明显降低锅炉低频噪声,改善周边噪声环境。

Abstract:

For a vertical heat recovery boiler in a certain gas turbine power plant, it has problems of big noise and prominent lowfrequency noise, and because of its compact arrangement, the conventional measure of overall sound insulation enclosure could not be implemented. This paper studied the lowfrequency noise of boiler of this type, identified its source, developed a new noise reduction device according to the analysis result, and applied it in practice. The application result shows that the device could significantly reduce the lowfrequency noise of boiler and improve the surrounding noise environment.
