Description

OVERVIEW:

1.Purpose:

Silencers and spark arresters used in the exhaust system of marine diesel engines, as well as silencers or spark arresters installed in the exhaust system of boilers and other combustion equipment, can be referred to for implementation.

2.Definition:

3.Silencer:

A device that allows airflow to pass through and prevents or weakens the propagation of sound energy.

4.Spark arrester:

A device designed to extinguish sparks carried in exhaust gases from internal combustion engines and boilers.

5.Noise Attenuation LP

The quantity used to evaluate the acoustic performance of a muffler. The unit of noise reduction is decibels (dB (A)). According to different testing methods, the evaluation indicators of noise reduction can be divided into several types: insertion loss, sound transmission loss, end sound pressure level difference, and sound attenuation. This guide uses insertion loss to evaluate sound attenuation.

6.Pressure loss pt (pressure loss)

The average total pressure difference between the inlet and outlet of the muffler. The unit of pressure loss is Pascal (Pa). When the inlet and outlet areas of the silencer are equal, and there is no significant change in temperature or density of air along the silencer, the pressure loss is equal to the static pressure difference.

MATERIAL:

The materials used for silencers and spark arresters should meet the following requirements:

(1) Corrosion resistant materials or undergo anti-corrosion treatment;

(2) Flame retardant and smokeless toxicity;

(3) High temperature resistance;

(4) No asbestos content.
