Muffler----- Turbine exhaust muffler

1: Purpose
The exhaust muffler of steam turbine can be used for exhaust noise elimination of back pressure type, back extraction type, pure condensing type, extraction condensing type and industrial driving type steam turbine. This type of muffler not only has certain noise elimination ability in use, but also can ensure that the pressure of steam turbine does not rise in use. This type of muffler has been used in many power plants regularly and has been highly recommended and recognized by East China Electric Power Design Institute Our factory is also a professional manufacturer of this model.
2、 Principle of muffler
??? The exhaust muffler of steam turbine is made on the principle of through-hole rhombic sound blocking flow. The inlet pipe hole of noise elimination is of through-hole type. The perforated plate is used as the resistive sound sheet, and the baffle is of sound flow structure. It improves the noise elimination performance by using the diamond shaped bending sound absorption and the thickness change of sound absorption layer in the channel. It not only has high noise elimination, wide frequency band, but also has low air flow resistance, which can ensure the sound elimination effect and ensure the back of steam turbine The pressure did not increase.
3、 Order selection of muffler
When ordering this type of muffler, the following information should be provided:
(1) How much emission (T / h), pressure and temperature.
(2) Type of steam turbine;
(3) Outer diameter and wall thickness of exhaust pipe;
4、 Specification and model

TDB turbine exhaust muffler
1: The purpose of TDB type steam turbine exhaust muffler is as follows
TDB type steam turbine exhaust muffler can be used for back pressure type, back extraction, pure condensing, extraction condensing and industrial drag type steam turbine exhaust. This type of muffler not only has certain noise elimination ability, but also can ensure that the pressure of steam turbine does not rise in use. This type of muffler has passed through many power generation processes The plant (station) is often used, which reflects the situation very well.

2、 The principle of TDB turbine exhaust muffler is as follows
After one expansion, the exhaust gas is discharged by the combined multi-material composite structure sound barrier and sound absorption cover again. The whole equipment has the characteristics of high noise attenuation value, wide frequency band and low air flow resistance.
