Release of steam to atmosphere creates noise which is dangerous to plant personnel and is environmentally unacceptable. Steam may be released from either low pressure or high pressure as part of boiler start up system, a bypass vent or a safety relief valve vent system. In each case Baffles Cooling System offers the most economical approach by optimizing silencer design to produce a guaranteed solution through selection of silencer pressure drop and flow velocities appropriate to the duty. Not all steam that is vented is dry, so where there is moisture carried in the steam flow BCS can provide a separator element to remove the excess moisture and prevent this hot liquid from being exhausted out through the vent to fall as hot rain in the area surrounding the vent. The pressure drop across the inlet diffuser is selected according to the duty of the silencer, we can examine the pressure losses through the pipework and recommend the most suitable silencer pressure drop for the vent duty. Silencers may be packed or pack free diffuser only types, depending on the duty requirements. Where a packed silencer is needed the packing material will often be chosen from glass fibre, mineral or ceramic fibre as considered appropriate for the operating conditions. The structural design of the our steam vent silencers are given the same thorough attention as its acoustic design. The external shell is constructed of seamless pipe in smaller sizes and continuously welded rolled plate in larger diameter silencers. Silencers may be mounted horizontally or vertically, pads or cradle type supports are available for easy installation.   Steam Vent Silencer Features Heavy gauge perforated sheet is used. Drilled on diffuser pipe as per ANSI standards. Lifting lugs and saddle are provided with proper calculating load and stress. Diffuser Pipe is checked by conducting Hydro Test. 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.       Optional Features for Steam Vent Silencer: High Temperature Acoustic packing material Material Selection options(Glass Fibre, Mineral or Ceramic Fibre) Manhole Inspection Extra Support lifting Lug, Support Saddles etc Special Paints Side Nozzle Opening for Multi inlet process Types of Steam Vent Silencer offered by BSC: Start up vent silencer Super heart header safety valve vent silencer Steam ejector vent silencer Turbine vent exhaust silencer Turbine warm up 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.       Design Enquiry Sheet for Steam Vent Silencer: Medium Flow rate Upstream Pressure of the Valve Upstream Temperature of the Valve Allowable Pressure drop Line Size Unsilenced Noise Level (dB at distance)
