随着我国石油化学工业的迅速发展,加热炉噪声成为石油化工厂的一个主要噪声源,噪声级可达110分贝(A)左右。由于其低频成分多,声音传播远,不仅危害工人健康,而且也严重污染周围环境。 1973年以来,我们和石油设计院、胜利炼油厂的同志一起开展了对自然通风式的加热炉降低噪声的研 With the rapid development of petrochemical industry in our country, the noise of heating furnace has become a major noise source in petrochemical plants, and the noise level can reach about 110 dB (A). Because of its low frequency components, sound propagation far, not only endanger the health of workers, but also seriously pollute the surrounding environment. Since 1973, we have worked with comrades of the Petroleum Design Institute and Shengli Refinery to reduce the noise of naturally ventilated reheating furnaces
