In order to establish the complete dynamic simulation model for the heat recovery steam generator and develop an advanced drum level controller, the methods of probability and time series were used to analyze the field data on drum level sloshing noise. The mean value of the drum level was removed and the field data was de-trended to get the true sloshing noise. Meantime, the AR model was set up for the drum level sloshing noise, and simulation results show that the model realizes matching simulation of the drum level noise signals in the power spectrum. The model can also match the drum level noise successfully in the time domain.

为建立完整的余热锅炉系统动态仿真模型，并基于此模型开发先进水位控制器，采用概率统计和时间序列分析的方法，对现场采集的汽包水位晃荡噪声信号进行了分析，去除汽包水位均值和趋势以获得真实的汽包水位晃荡噪声，建立了相应的汽包水位晃荡噪声仿真AR模型；模型的仿真结果表明：AR模型从功率谱上对信号数据进行了匹配模拟，且使用该模型作为噪声模块在时域上对汽包水位晃荡噪声信号进行了成功匹配。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.

通过选用耐油性好的橡胶隔振器减少固体传声，可降低噪声约2 dB；设置半封闭式机组隔声屏障可降低生产车间工作区域内的噪声达13 dB，并且适合瓦斯发电气源中含有H2S、CO等有毒有害气体的特点，不需增加强制通风措施；在生产车间四周墙壁和顶棚上敷设吸声体，最大可降低空间噪声8 dB；根据瓦斯发电机排烟噪声频谱特性设计的阻抗复合式消音器的消音量可以达到30 dB以上。
