Lowering sound levels at an industrial site

Details

Published: 01 February 2024

French regulations regarding the limitation of environmental noise stipulate the following, with regard to a Facility Classified for Environmental Protection (FCEP):

• if the ambient noise level in the Regulated Emergence Zones - REZ - (including installation noise) is between 35 dB(A) and 45 dB(A) then the admissible emergence is 6 dB(A) during the day and 4 dB(A) at night
• if the ambient noise level in the Regulated Emergence Zones - REZ - (including installation noise) is greater than 45...

Noise reduction of a combustion turbine and a generator

Details

Published: 04 January 2024

ITS participated in the noise reduction of a combustion turbine and a generator in a power plant in Southeast Asia, designed for simple cycle operation. With a power greater than 80 Megawatt (80MW), this fzacilty is one of the smallest involving large capacity gas turbines (for some, the unit power can exceed 550 MW in a simple cycle and 800 MW in a combined cycle, which is not is not very far from a nuclear unit and notably allows faster construction and therefore commissioning of the...

Limitation of sound emergence from noisy industrial equipment

Details

Published: 12 December 2023

ITS participated in the limitation of the sound emergence of noisy industrial equipment in an energy production plant in South-East Asia, based on the use of a combustion turbine coupled to a steam turbine and a generator. This combined cycle gas plant - the largest in the country, with a power of more than 580 MW - will provide electricity to more than 680,000 inhabitants. The main sources of noise to be considered in such cases were:

• the turbine itself
• a compartment for the load
• a plenum...
