An industrial site involves machines and facilities that contribute not only to the production of capital goods or energy, but also to the production of noise.

In some industries, an observable trend (among others) is the deployment of capacities with power per unit significantly increased, which is often accompanied by higher noise emissions.

Indeed, in many cases, the sound emission is an increasing function of the power (e.g. mechanical or electrical) of an equipment or a facility.

Thus, in the power generation sector, the demand of some operators to have gas-fired power plants with a power of nearly 400 MW per unit has led some Original Equipment Manufacturers (OEM) to increase their vigilance with respect to noise-related issues, whether in relation to the hearing health of workers or to the tranquility of the neighborhood, which should not be affected by noise emissions, even at long distance.

ITS will take part in the prevention of noise pollution in an industrial site and nearby in the Indian subcontinent for the production of energy using 2 combustion turbines, being for the time being the maximum possible to be reached in terms of power per unit for such machines.

Apart from the air intake and exhaust (which also require high-tech soundproofing equipment), it will therefore be appropriate to control different noise sources for each turbine:

  • the compressor, the combustion chamber, and other subassemblies and auxiliary elements
  • the load compartment
  • the portions of the envelope of the intake and exhaust ducts to be encapsulated
  • related equipment e.g. gas module, generator

For some of these sources of noise, the overall sound power level to be considered approaches 140 dBA with a very wide distribution of sound (from low frequencies to high frequencies) which necessitates state-of-the-art soundproofing equipment both for the building envelope intended to limit the propagation of noise and for the (complex) ventilation systems, which must also be sufficiently silent.

The assembly and disassembly of all soundproofing equipment must be achieved in record time, sometimes with local manpower having a margin of progress for performing such work optimally.

All these constraints, as well as the shortened cycle time for the design and construction of the power plant, will help ensure that this project is once again an opportunity for ITS and its business partners to face the challenges of all orders that will make even more appreciable, in fine, the sense of work accomplishment.
