摘要
锅炉排汽管因其压力高，排汽量大，从而产生很大的噪声，直接影响着生活、工作及心身健康是一大社会公害。本文叙述了设备噪声的控制标准，小孔消声器的消声原理及设计计算方法，并附有实例。为工业锅炉房的消声降噪提供了一种方式。
Pressure of steam discharge pipes of boiers is high and steam discharge amount is lange. Therefote, noise is produced. The noise has a harmful effect on life, work and health of the people. It is social effects of pollution. The paper presents noise control standands of equipments. It also describes elimination principls and calculation methods of a small hole deafener. There ane some examples in the paper. It provides a useful method of noise elimination for an industrial boiler room.
