Spark Arrestor

Quantity

Spark Arrestor @ Spark Arrester

ISTIQ SPARK ARRESTOR @ SPARK ARRESTER remove sparks, soot and solid matter while preventing noise instead of muffling it. When exhaust gases enter the silencer, a special stationary impeller whirls the gases to throw out all solid matter, and at the same time, partially breaks up the exhaust slugs. Cleaning efficiency is high. Exhaust gases then enter the snubbing section in which the energy of the exhaust slug is further dissipated without interfering with the flow of low energy gases to the atmosphere. Model IXSA Provide Attenuation up to 30 dB.

Applications

ISTIQ SPARK ARRESTOR are designed to efficiently reduce inlet and discharge noise of diesel engines, blowers, vacuum pumps, compressors and all situations requiring control of intake or outlet equipment noise.

Construction

Silencers are constructed from heavy gauge controlled cold quenched sheet steel with all welded construction. Internal components are stiffened and braced to minimise resonances and vibration induced fatigue. Flanges are supplied to Table C or American National Standard Institute (ANSI) requirement. Threaded pipe ends are to BSP or metric threads. Drain plugs are fitted as standard for removal of condensate. All external surfaces are finished with high
quality silicone based heat resistant aluminium paint which provides lasting protection at temperatures up to 600oC.

Selection Guidelines

When designing an exhaust system there are a number of factors that should be considered to maximize the design in terms of performance and cost. A few of the items that should be taken into consideration include:
  • Acoustic Environment into which exhaust is discharging
  • Engine Rating, i.e.
  • Exhaust flow
  • Allowable engine back pressure - Engine exhaust outlet noise level
  • Engine Exhaust Outlet Design, i.e. single or dual outlets
  • Exhaust Piping Arrangement within engine room
  • Exhaust Piping Support, Anchoring, and Guiding
  • Exhaust Stack Height
  • Configuration of Exhaust Silencers, i.e. single or dual inlet

Duct Silencer

Quantity

Duct Silencers / Attenuators

Application Notes

Whenever ventilation is required in the enclosed compartment and at the same time noise is to be controlled, installing duct silencers or attenuator are the best way to solve the problem. The silencers permit air to flow through while reduce the noise by absorbing it. In selecting a silencer, a balance between noise attenuations and pressure drop need to be considered carefully.  By using internally developed software, ISTIQ NOISE CONTROL can help to make the right choice quickly and most importantly, accurately.

Introduction

ISTIQ DUCT SILENCER are designed to efficiently reduce noise by generator sets, air handling systems, compressor, blower system and all situations requiring air intake and outlet for these equipments to operate.
A duct silencer should always positioned in the plant room and if possible as close to the noise source as possible. Normally for a single equipment, two units of duct silencers - intake and discharge is required to effectively reduce the noise to a desired level.

Construction

ISTIQ DUCT SILENCER are available in two different models, which basically have two different thicknesses of splitters - 200 mm and 300 mm. The thicker the splitter the better performance at lower frequencies. Each of the models have six length sizes from 900 to 3000 mm. The cross sectional area has no limited size. 

ISTIQ DUCT SILENCER will be supplied in sections whenever the silencer dimension exceeded 2100W x 2100H x 2100mmL. This will make the transportation and installation easier. The assembly of sectionalized silencers to be done at site.

Vent Silencer

Quantity

Vent Silencer @ Blow Off Silencer

ISTIQ VENT SILENCER reduce the noise produced by the expansion of gas or steam from elevated pressures to atmospheric pressure. These absorptive silencers are used to suppress noise generated by high velocity gas streams such as steam vents, safety relief valve outlets, system blow downs and purge outlets. Each vent silencer is designed to attenuate the noise level to the required sound pressure level criteria at a given distance from the silencer.
Model IVS - Acoustic Diffuser & Expansion Attenuation - 30 dB

Applications

VENT SILENCER effectively silence high-velocity air, steam, and gas vents and blowdowns to atmosphere where
sonic or critical conditions exist in the valve or pipes. Typical applications include:
  • steam boiler relief valves
  • superheater header relief valves
  • boiler startup and purge
  • high-pressure air vents
  • natural gas blowdowns
  • switch valves
  • compressor blowoffs
  • autoclaves
  • steam ejectors
  • pressure valve
  • Steam turbine silencer

Construction

Typical VENT SILENCER are welded heavy-duty units. The inlet nozzle and diffuser are constructed of steel and are welded. The diffuser provides controlled pressure expansion to atmosphere and uniform flow distribution through the acoustic section of the silencer. The lined inlet plenum (expansion chamber) of the silencer is designed with a double shell separated by a layer of acoustic insulation and sound-deadening material. The inner shell is solid to prevent shell radiated noise and migration of the acoustic fill. The transmission loss across the plenum and bottom head is comparable to the silencer attenuation.

Selection Guidelines

Use the following design information from the valve data sheet for system analysis and silencer selection:
  1. Type of gas
  2. Molecular weight or specific gravity
  3. Ratio of specific heats
  4. Flow rate (lb/hr, ACFM or SCFM)
  5. Pressure and temperature upstream of valve and silencer
  6. Maximum allowable pressure drop (PSI) for valve and silencer
  7. Manufacturer’s name, and valve type and size
  8. Unsilenced noise levels from valve (if available)
  9. Silenced noise level (required at desired distance from source)
  10. Silencer inlet size and pressure rating
  11. Inlet orientation, axial or side
  12. Silencer orientation, vertical or horizontal
  13. Piping arrangement, including schematic if available
  14. Other required options
