1、 Application of steam muffler:  

A steam muffler is a muffler developed specifically for steam emissions. Boiler steammufflerIt is mainly used for effective noise reduction of steam emissions and other gas emissions from industrial boilers in power, petroleum, chemical, metallurgical, textile and other industries. Installing steam silencers is an important measure to eliminate steam emission noise.The noise emitted by steam mufflers and other thermal equipment related to steam emissions far exceeds the values specified in China's "Industrial Enterprise Boundary Environmental Noise Emission Standards" (see appendix). This seriesSteam mufflerIt is developed based on the principle of resistance, spray, and resistance composite noise reduction, and has the advantages of large noise reduction, small size, light weight, and easy installation.

twoClassification of steam silencers:

1. Steam safety door silencer

As is well known, for the safety doors of boilers and other thermal devices, the exhaust steam should not only avoid excessive noise, but also allow the steam flow to be smoothly discharged. Therefore, the commonly used multi-stage throttling and small hole injection noise reduction methods should not be used. This limitation has always been a design difficulty for safety door mufflers, and it is also the reason for the poor noise reduction effect of safety door mufflers. The muffler used for safety doors also adopts the principle of anti spray and anti blocking noise reduction, in which a large hole expansion is used instead of a smaller diameter control hole, which further strengthens the anti spray and anti blocking noise reduction mechanism in structure and achieves the ideal noise reduction effect.
2. Low pressure steam muffler
Various industrial and mining enterprises use a large number of low-pressure boilers with a pressure of 1.3 MPa or less, and there are also a large number of low-pressure thermal devices in the power plant thermal system, such as back pressure steam turbines, deaerators, auxiliary gas compressors, steam turbine oil pumps, boiler continuous discharge, and periodic discharge expanders. The exhaust pipe of the above equipment requires a lightweight structure and a more convenient installation of a silencer. Our factory has designed deaerator series, back pressure steam turbine series, and other series of products for different noise reduction objects, which can meet the requirements of users.

VIsteamInstructions for Ordering and Selecting Mufflers:
Our company's steam muffler series is carefully designed according to the user's steam emission target and emission requirements. Therefore, only products that meet the emission target, steam parameters, and emission volume can achieve ideal noise reduction effect. Therefore, the following parameters must be provided when ordering a muffler:
① For thermal power plants, the turbine model, boiler capacity, steam pressure, and temperature should be provided;
② Object of use (such as for boiler overheating discharge or steam drum safety valve discharge, etc.);
③ Emissions T/H;
④ The original outer diameter and wall thickness of the exhaust pipe;
⑤ If it is necessary to entrust our factory to carry out installation design, the original exhaust pipeline installation diagram should be provided.
For models not listed in this product manual, users can provide the relevant information mentioned above, and our factory will select them on their behalf.
7、 Installation instructions for steam muffler:
① The exhaust muffler should be installed perpendicular to the roof of the factory, and the muffler bracket should be fixed to the factory building with a steel support.
② To increase the wind resistance of the factory roof at high altitude, the exhaust muffler body adopts a support type support. Therefore, the exhaust pipe in front of the exhaust muffler should have an expansion bend to absorb thermal expansion. If the original exhaust pipe section is already equipped with a drain pan in the vertical direction, the expansion bend should not be installed.
③ The bottom of the exhaust muffler body is designed with drainage pipes or holes, and the holes should be checked for smoothness.
④ The hole where the exhaust pipe passes through the factory roof platform should have a thin steel plate made rainproof cover (as shown in Figure 3).
⑤ For safety doors, in principle, one safety door is equipped with one muffler. There are two types of safety doors: single seat and double seat. For double seat safety doors, the exhaust pipe can be merged into one main pipe and connected to the muffler during installation. However, for double seat safety doors with large exhaust volume, two mufflers can also be installed.
⑥ For exhaust silencers with small displacement used in deaerators, jet type air extractors, etc., the external design is tubular, making installation more convenient. Installation method: The exhaust muffler is installed vertically along the walls and columns of the main factory building. Install steel sliding brackets on walls and columns, and install silencers and pipelines on them. The discharge outlet of the silencer should face the direction of the roof. It should be noted that this type of muffler comes with fixed supports when it leaves the factory. When using a sliding bracket installation, the fixed supports can be omitted.

The standard specifies the emission limits and measurement methods for environmental noise at the boundary of industrial enterprises and fixed equipment factories (see Table 1)Unit db (A)
