Steam emission muffler

 1、 Usage and product features:
The noise emitted by steam boilers and related thermal equipment far exceeds the values specified in China's "Industrial Enterprise Noise Health Standards". For this purpose, our company has produced a series of utility model steam mufflers, mainly used for effective noise reduction of steam emissions from thermal equipment such as boilers and turbines in industrial sectors such as power generation, chemical industry, metallurgy, and textiles.
This series of mufflers is developed based on the principle of composite noise reduction of resistance, spray, and resistance, and has the advantages of large noise reduction, small size, light weight, and easy installation. According to different purposes, our company has produced the following forms:
1. Boiler ignition exhaust muffler (TB type)
This type of muffler is designed based on the most reasonable noise reduction principle. High pressure steam enters the pressure reducing body through a large volume expansion after passing through a flow control system in the muffler, forming low-pressure steam that is then sprayed out. During this process, some of the internal energy in the steam flow is converted into sound energy of a certain frequency. Although the noise power is greatly reduced, it often remains higher than the standard value due to exhaust deviation from the design value and other reasons. For this purpose, a double-layer structure soundproof cover was designed outside the pressure reducing body, which was designed based on the spectral characteristics of the residual noise emitted by the pressure reducing body to effectively absorb the residual noise. After the user installs it as required, the total noise reduction should reach 36-42 decibels.
2. Low pressure steam muffler (TD type)
Various industrial and mining enterprises use a large number of low-pressure boilers with a capacity of 0.13Mpa and below, 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 air extractors, steam turbine oil pumps, continuous and periodic boiler discharge, etc. The exhaust pipe of the above equipment requires a lightweight structure and a more convenient installation of a muffler. Our company has designed specialized deaerator series, back pressure turbine series, and other series of products for different noise reduction targets, which can meet the requirements of users.
