Noise limitation of production equipments

Noise limitation of production equipment is often necessary, in general, in order to respect regulatory texts in relation, on the one hand, with the protection of the workers against the risks related to noise exposure and, on the other hand, with the preservation of the environment.

This is particularly the case of an electricity generation facility with gas turbines (combustion turbines), noise being emitted by the various subsets making up each turbomachinery (in addition to noise emissions...

Reduction of noise emitted by two combustion turbines with high power output

In a power plant with gas turbines (combustion turbines), some airborne noise is emitted by the various subsets making up each turbomachinery (in addition to noise emissions associated with the mouths for air intake and exhaust not included in the current project, although regularly studied and subject of simulation and design work by ITS as part of other projects in the field of energy production):

  • the turbine compartment i.e. compressors, combustion chamber, turbine
  • the auxiliary...

Construction of 2 silencers for depressurization devices outlets for a test bench

In a test bench, a depressurization device outlet is a very powerful noise source potentially causing sound nuisance for personnel of the operator operating in the vicinity as well as for the neighborhood (including sometimes long distance). It is often necessary to use in such cases a soundproofing equipment of high technology to ensure compliance of the installation on the one hand with respect to the legislation on noise at work and on the other hand with respect to the regulation in terms...
