The exhaust silencer integrates the reasonable noise reduction principle of the PB-type exhaust (steam) silencer. After passing through a once-through flow control within the silencer, the high-pressure steam enters the pressure-reducing body. It is then expanded and pressure-reduced further in a large-volume chamber, forming low-pressure steam before being ejected. During this process, part of the steam's internal energy is converted into sound energy of certain frequencies. Although the noise power is significantly reduced, the exhaust noise often remains above the standard value due to factors such as the steam exhaust deviating from the design value.

Usage

This series of silencers is mainly used for effective noise reduction in power, chemical, metallurgical, mining, and textile industry boiler steam exhausts, fans, and other equipment.

Features

Boiler Ignition Exhaust Muffler (TB Model)

To suppress the noise of high-pressure steam emissions, this type of silencer is designed based on a comprehensive application of reasonable noise reduction principles. After high-pressure steam is once controlled within the silencer and enters the pressure-reducing chamber, it is expanded through a large volume, forming low-pressure steam that is then emitted. During this process, a portion of the steam's internal energy is converted into sound energy of a certain frequency. Although the noise power is significantly reduced, the noise level may still exceed the standard due to various reasons, such as the steam emission deviating from the designed value. To address this, a double-layered soundproofing cover is designed around the pressure-reducing chamber, tailored to the spectrum characteristics of the remaining noise emitted by the chamber. It is designed to effectively absorb the residual noise. After installation in accordance with the user's requirements,

Total noise reduction up to 36~42 decibels.

Boiler Steam Safety Valve Muffler (TA Type)

For the safety valves of boilers and other equipment, the exhaust steam should not only avoid excessive noise but also allow for smooth discharge. Therefore, the commonly used methods of multi-stage throttling and small-hole injection for noise reduction are not suitable. This limitation has always been a design challenge for safety valve silencers and a reason for their poor noise reduction performance. This novel safety valve silencer also employs the noise reduction principle of resistance, injection, and restriction, replacing the smaller diameter flow control holes with larger holes for expansion, thereby strengthening the resistance, injection, and restriction noise reduction effects structurally. This achieves an ideal noise reduction effect.

3. Low-pressure Steam Silencer (TD Model)

A large number of industrial and mining enterprises use low-pressure boilers of 0.13Mpa and below, and there are also numerous low-pressure thermal equipment in power plant thermal systems, such as back-pressure turbines, deaerators, auxiliary exhaust blowers, turbine oil pumps, continuous blowdown of boilers, periodic blowdown, and more. The exhaust pipes of the above equipment require the installation of noise suppressors that are lightweight in structure and easier to install. Our company designs dedicated noise suppressors for different suppression targets, which can meet the requirements of our customers.

4. Blowing Ash Duct Silencer (TC Model)

After the installation and maintenance of steam boilers and related thermal equipment pipelines are completed, a steam flushing and cleaning of the pipeline debris is required. This process will generate a significant amount of noise. The TC type silencer employs a three-stage silencing structure, effectively reducing noise through the principles of resistance, spray, and obstruction, while internally integrating the design of the TB and TA types.
