Environmental regulations require, among other things, that noise levels be kept within certain acoustic limits, and power generation plants are no exception. In power plants, the high pressure steam section feeding the turbine typically produces atmospheric discharges from safety or control valves with sharp pressure drops, which generate high noise levels. These situations can be avoided with vent silencers which, placed downstream of this equipment, provide the necessary attenuation according to the design calculations. There are two traditional silencer designs, absorption and diffusion, and they can be combined in a single design. Our technical team can calculate and propose complete solutions of safety and severe service control valves together with the appropriate silencers, under a single warranty for your project.
