本文主要介绍船舶柴油机排气熄火消声器的试验研究情况。实验室台架试验与实船使用结果表明,本项试验研究确定采用的湿式卧、立型熄火消声器不仅对于降低柴油机排气温度、熄灭排气中的火焰与火花具有十分明显的效果,而且在降低排气噪声及排气除尘防污方面也有一定的作用。另外,安装此类熄火消声器对柴油机的运行特性基本上无不良影响。因此,本项试验研究取得的成果具有推广应用价值。 This article mainly introduces the experimental research of marine diesel exhaust muffler. The results of the laboratory bench test and the actual ship show that the wet type and vertical flameout muffler used in this pilot study not only have the obvious effect of reducing the exhaust gas temperature and extinguishing the flame and spark in the exhaust gas, Reduce exhaust noise and anti-pollution exhaust dust also has a role. In addition, the installation of such flameout muffler on the operating characteristics of diesel engine basically no adverse effects. Therefore, the results of this pilot study have the promotion and application value.
