锅炉房主要噪声源有鼓风机、引风机、锅炉给水泵等,其中以引风机的噪声级最高,达95分贝(A),且噪声峰值集中在低、中频,同时产生强烈振动,加速度振动级达90分贝,站在机房及相邻居民室内地坪上亦明显地感觉到。另外,由于引风机与锅炉的排烟道直接相连,烟道温度达二、三百度,中间即使有除尘器,至引风机的温度仍达近百度,故封闭式的隔声罩就不宜使用,否则会引起传动皮带的损坏和电机烧毁的事故。根据引风机安放位置的不同(有的在底层;有的在楼面或屋面上),考虑隔振降噪的侧重点及方法
The main noise sources of the boiler house are air blower, induced draft fan and boiler feed pump, among which the induced draft fan has the highest noise level of 95 dB (A), and the peak of noise concentration is at low and medium frequency with strong vibration and acceleration vibration level 90 decibels, standing in the engine room and adjacent residents indoor floor clearly felt. In addition, as the induced draft fan is directly connected to the boiler exhaust passage, the temperature of the flue reaches two or three hundred degrees. Even if there is a dust collector in the middle, the temperature of the induced draft fan is still close to Baidu. Therefore, the enclosed acoustic enclosure should not be used, Failure to do so could result in damage to the drive belt and motor burnout. Depending on the location of the induced draft fan (some in the bottom; some in the floor or roof), to consider the focus of vibration and noise reduction and methods
