We are engaged in manufacturing and supplying a gas turbine exhaust silencer. These gas turbine exhaust silencer is used to reduce the exhaust noise of the fluid gases when venting through the stack. The fluid is guided through the annular space of the acoustic packing where the excess noise is absorbed. It is designed as per the customer requirements like acoustic performance, pressure drop, etc. We supply the acoustic packing for these silencers in circular or rectangular shape.

When one is looking to attain noise reduction by the means of a silencer, BCS offers a wide range of vent silencers for pressurized gas for various applications related to acoustic insulation, soundproofing ie., protection of workers against noise, preservation of acoustic environment, limitation of noise emissions in the energy sector. The blowdown of natural gas systems must typically be done quickly in a very short time span during maintenance operations on pipelines. This often produces noise readings well above tolerable levels. Natural gas silencers control blowdown noise through a reactive-absorptive process, which provides good attenuation across all octave frequency bands. The selection and design of natural gas silencers is dependent on the following application specific factors. Noise attenuation requirements Evaluation of natural gas flow Blowdown time limits Most cost effective approach to meet needs Durability and performance for the given application environment We offer a powerful solutions at a reasonable cost in response to all the needs in the matter of soundproofing by means of equipment that is either standard or tailor made for which the quality of design and execution meets the highest level of requirement in this area for an efficient fight against noise. The vent silencers for pressurized gas offered by us allows the reduction of noise for process facilities using pressurized fluids like air, oxygen, nitrogen etc., notably for the chemical industry, oil & gas sector, heavy duty industries and also for power plants Gas Vent Silencer Features: Heavy gauge perforated sheet is used. Lifting lugs and saddle are provided with proper calculating load and stress. Heat Resistant Aluminum Paint is applied on the surface area (800°C) based on customer requirement. Quality acoustic fills and Insulation is used. Sandblasting is done on the surface area. We have qualified welders for all types of welding joints for structural work. We have approval from third party inspection for WPS, PQR and WPQ records for all the welding positions like 1G, 2G, 3G, 4G, 6G. We have NDE LEVEL-II inspector for RT, UT, VT, PT, MT. Gas Vent Silencer Optional Features: High Temperature Acoustic fill Material Material Selection Inspection of opening such as Manhole Extra Support lifting Lug, Support Saddles Special Paints Side Nozzle Opening for Multi-inlet process Type of Gas Vent Silencer: Air vent silencer Oxygen gas vent silencer Nitrogen gas vent silencer Blast gas vent silencer CO₂ gas vent silencer Diffuser Pipe: A diffuser is a device that utilizes a part of the Kinetic Energy of the fluid passing through the machine by gradually increasing the cross sectional area or chamber through which it flows, so as to decrease the speed and increase the pressure. Diffuser pipe provides energy dissipation and modification of the noise spectrum for easier attenuation. Stream is entered into the pipe as high speed jets into many small holes of the pipe. The diffuser creates a back pressure on the valve. This leads to the reduction of the pressure drop across the valve which in turn aids in the reduction of the noise generated by the valve and reduces the velocity at downstream of the valve. Increasing pressure drop at the inlet diffuser does not affect the required diameter of the vent silencer. Our Diffuser pipe design is in accordance to the ASME Standard, Sec VIII-Div-1 where the operating pressure is equal to the valve back pressure. The operating pressure is directly proportional to the mass flow through the diffuser. Chamber A Chamber is an expansion unit or section. It is setup where the fluid flow enters the Acoustic Infill absorption area. Shell Shell is designed based on the mass flow rate of the steam. Shell thickness maximum 6 to 8 mm. Shell material used are SA516 GR70, SA36, SA240 TP304 based on design and Customer requirements.
