郝力维(包头市卫生防疫站)报道:该厂为大型火力发电,产生噪声主要来自汽轮发电机、磨煤机、励磁机、各类泵、风机等同时存在。其中以30,000KVA汽轮机为95dB(A),60,000KVA汽轮机为97dB(A)。磨煤机为100dB(A),水泵96dB(A),软水泵95dB(A)另如汽机车间4号主闸门产生空气动力性噪声可高达102dB(A)根据各类设备频谱特性分析,噪声主要以低中频、宽频带的连续性稳态为主其强度较高。
Hao Liwei (Baotou Health and Epidemic Prevention Station) reported: The plant is a large-scale thermal power generation, the noise generated mainly from the turbine generator, coal mill, exciter, all kinds of pumps, fans, etc. exist. 95MW (A) for a 30,000KVA turbine and 97dB (A) for a 60,000KVA turbine. Pulverizer 100dB (A), the pump 96dB (A), soft water pump 95dB (A) Another such as steam turbine plant main gate No. 4 produces aerodynamic noise up to 102dB (A) According to various types of equipment spectral characteristics of the analysis, the main noise Low-IF, wide-band continuity of the steady-state-based its high intensity.
