Power Generator

Generators require an efficient ventilation and acoustic treatment.

Context

Ever since the discovery of electromagnetic forces in 1733 until the invention of energy distribution systems, technologies have evolved around the making of more and more complex machines using the electric current.

To overcome the possible failures and occasional breakdowns of the public network, generators (backup electric sources) have been developed and improved. Nowadays they are essential and meet several requirements depending on their use.

Generators use

Depending on the public network capacities and the energetic needs of the application, generators can be used in different ways:

  • Spike energy production
  • Electric energy production
  • Backup production
  • Reversed backup production

Definition and functioning

Issue

Ventilation

When operating, the generator consumes fuel and produces electric energy and heat, which can cause malfunctions. Ventilation is important so as to prevent the system from overheating.

Preheating

Generators producing a high voltage are also larger and need the constant heating of the engine in order to optimize their start.

Acoustic pollution

A generator generates noise and the acoustic level in its vicinity can sometimes reach high number. (up to 120-130 db(A))

Solutions

Ventilation

The ventilation is made through fresh air intake and air exhaust dampers.

Preheating

In order to avoid for the dispersion of the heat emitted outside the premises (for energy saving purposes), shutoff dampers positioned on the air intake and exhaust are closed when the generator is turned down.

Acoustic

Radiated noise

It is essential to attenuate the noises generated by a generator through the use of devices such as acoustic enclosure, walls’ treatment or sound-proofing doors.

Propagated noise

The premises are also acoustically treated with silencers, anti vibration plots or splitters placed on the air intake and air exhaust.
