K350型氧气透平机噪声高达101.5dB(A),电机功率为2500 kW,要求防火防爆,若采用全封闭隔声罩,虽然能有效地解决噪声污染问题,但透平机和电机的温升问题难以解决。因防火防爆要求不得采用通风机排风,故氧气透平机噪声控制难度较大。上海第五钢铁厂和浙江黄岩东门环保器材厂共同努力,设计制造了一种带消声百叶的、采用自然通风散热的隔声罩,成功地解决了这一问题。1987年1月16日,由上海市冶金局主持,在上钢五厂通过了评审验收。
K350-type oxygen turbine noise up to 101.5dB (A), the motor power of 2500 kW, requires fire and explosion, if the use of fully enclosed noise enclosures, although it can effectively solve the problem of noise pollution, but turbine and motor temperature rise The problem is hard to solve. Due to fire and explosion requirements shall not be used fan exhaust, so oxygen turbine noise control more difficult. Shanghai No. 5 Iron and Steel Plant and Huangyan, Zhejiang East Gate Environmental Protection Equipment Factory work together to design and manufacture of a noise with louvers, the use of natural ventilation cooling hood, the successful solution to this problem. January 16, 1987, presided over by the Shanghai Metallurgical Bureau, Wuchang in the steel passed the assessment acceptance.
