DISCHARGE SILENCERS

Product catalog summary

Operating Principle: The SP30 discharge silencers operate on a mixed principle involving progressive and controlled fluid expansion followed by an absorption zone. The fluid passes through a diffuser with concentric perforated elements and then through an absorption zone, all enclosed in a cylindrical body with sound-absorbing lined walls.

Description: SP30 silencers are designed to allow free expansion of their components. They are open to the atmosphere, eliminating the need for official inspections or hydraulic tests. For high-temperature fluids, an expansion device is necessary to accommodate pipe position variations.

Protection: The exterior of the silencers is protected by sandblasting, inorganic zinc silicate, and high-temperature paint. The inner metal parts are also treated with high-temperature paint.

Compliance: These silencers comply with Directive 97/23/CE, as confirmed by TÜV Rheinland Ibérica Inspection, Certification & Testing, S.A.

Applications: SP30 silencers are suitable for thermal and power plants, solar thermal power plants, cogeneration plants, petrochemical industries, turbines, HRSG or boilers, liquefied gas plants, and compressors.

Acoustic Efficiency: The silencers provide sound attenuation, with specific attenuation values in dB(A) at dominant frequencies in KHz.

Assembly Instructions: Optional accessories include inlet flange, gaskets, special steels, external protection, weather protection elbow, horizontal supports, bird screens, expansion compensators, flow limiters, and sealed floating trays. Silencers can be mounted vertically or horizontally, and precautions must be taken to protect people and property during discharge.

Installation Considerations: Remove transport sealing discs, check flow direction, fix brackets, connect pipes, ensure no condensate accumulation, connect condensate drain, and provide sound insulation for discharge mechanisms.

DISCHARGE SILENCERS OPERATING PRINCIPLE SP30 silencers are of the mixed type, progressive and controlled fluid expansion and absorption zone. The exterior is protected by SA 2.5 sandblasting, inorganic zinc silicate and a finishing coat of hightemperature paint. The inner metal parts are treated with high-temperature paint. The fluid flows through a diffuser consisting of a series of concentric perforated elements with an increasing cross-section and then passes through an absorption zone. The diffuser is enclosed in a cylindrical body with sound-absorbing lined walls protected by perforated...
