Is it necessary to install a silencer behind the turbine high-pressure steam discharge valve?
Thread Content
I would like to ask whether a silencer should be installed after the vent valve on the high-pressure steam line and the safety valve on the low-pressure steam line. 1. When the turbine is started up for the first time, during the pipe warming process with 4.0 MPa high-pressure steam, it is necessary to open the drain valve; this allows steam to be vented while water is drained, thereby reducing the pipe warming time. However, the sound generated by the drain line is quite loud – should a silencer be installed? 2. Should a silencer be installed after the safety valve on the low-pressure steam pipeline at the turbine outlet?
Regarding the issue raised by the original poster, the following suggestions are given: 1. To minimize the noise generated by steam emissions, it is recommended to install a silencer after the vent valve of the high-pressure steam line. 2. According to relevant safety valve specifications, no silencer should be installed on the pipeline downstream of the safety valve. This is mainly to prevent the silencer from developing high resistance due to corrosion or other factors over time, which could lead to blockages and thus affect the proper discharge of fluid after the safety valve activates.
Thank you to the moderator; due to the loud noise generated by steam release when the safety valve suddenly activated, we are considering whether to install a silencer.
At the end of the pipeline behind the exhaust valve in high-pressure steam pipes, a silencer must be installed; this has nothing to do with safety valves. As for low-pressure exhaust systems, whether a silencer is needed depends on the noise level in decibels – if it exceeds a certain threshold, then a silencer is definitely required. . . . . . However, the safety valve also serves to some extent to remove air bubbles. . . . . .
The explanation on the 2nd floor is very clear. I would also like to ask what points should be kept in mind when setting up this silencer? Hehe
