NOISE CONTROL ejectors

STEAM BLOWING noise reduction

The ejectors works as STEAM BLOWING noise reduction are no mechanical moving parts devices powered by a high pressure steam tank. The ejectors device is changing the flow of a free steam jet in order to reduce the noise. In fact is not reducing the noise but by changing the way to flow it produce lower noise. The final effect is to reduce the noise emission but is not about a reduction of an initial noise. The product was first designed and tested by Henri Coanda, working more than 20 years without any maintenance. (photo FourQuest Energy)
Usual ejector types for this application are:

FORMULA ONE echappements

The ejectors works for FORMULA ONE echappements are no mechanical moving parts devices powered by engine exhaust gases. The ejectors device is changing the flow of a free gases jet in order to reduce the noise. In fact is not reducing the noise but by changing the way to flow it produce lower noise. The final effect is to reduce the noise emission. The product was first design and test by Henri Coanda. It was observed that useful power of the engine was increased by the presence of the ejector systems. (photo www.globaltimes.cn)
