Gas Turbine Noise Control Systems

Acoustics India specialises in a wide range of Gas Turbine Noise Control Systems: gas turbine exhaust silencers, gas turbine exhaust system and acoustic enclousers. The gas turbine exhaust silencers are installed in the main stack as well as at the by pass stack. With the state-of-the-art computerised design facilities, the company is able to design aerodynamic profiled, least resistant acoustic baffles. The acoustic baffles are made of stainless steel materials with perforated skin packed with mineral fibres. Stainless steel wire mesh and fibre glass mat are provided for infill protection. For high temperature applications, a combined layer of mineral fibres and ceramic wool are used with stainless steel wiremesh and ceramic fibre mat for infill protection. For large stack silencers the acoustic baffles are pre-fabricated at shop and erected at sight inside the stack. For this purpose, the company uses mounting brackets which are welded to the stack and the baffles are inserted and positioned on the mounting bracket freely to allow thermal expansion both in longitudinal direction as well as in vertical direction upto 40 mm or as per the thermal expansion requirement. The aerodynamically designed splitters offer minimum resistant to the flow. And we have designed and supplied stack silencers to restrict the pressure drop across the silencer within 10mm of WC.
