The boiler room is a place with huge noise. The circulating water pumps, burners, fans and other equipment in the boiler room will generate a lot of noise during operation. The noise level generally exceeds the standard, which not only affects the normal life of nearby residents, but also causes greater physical and mental harm to the on-site workers.

Therefore, it is very necessary to carry out sound insulation and noise reduction in the boiler room.

Under normal circumstances, we will achieve the purpose of noise control by reducing sound sources, limiting noise transmission, blocking noise reception and other means. In specific noise control technologies, we can use three measures: vibration reduction, sound insulation and noise reduction.

After years of theory and practice, EPCB found that the burners of oil-fired gas boilers produce the most noise during operation, and most of the noise values measured are about 80-110dB(A), which causes great harm to the on-site workers.

The Harm of Loud Noise in the Boiler Room

1. Damage to human hearing and cause hearing loss

2. Affect the nervous system and make people grumpy

3. Affect the quality of sleep and cause cardiovascular damage

Therefore, in this case, many boiler users will reduce the noise emission limit of the burner by installing sound insulation equipment, so that the noise of the burner can be controlled within the range of the human body, and the harm of noise to the human body in the working environment can be solved.

How to Control Burner Noise?

The most common way is to use a soundproof hood for the burner.

The soundproof cover of the burner needs to be customized. 

Because:

1.The installation of each boiler equipment is designed in advance, and need to installed the sound insulation cover according to the height of the site base;

2. Different burner brands have different measurement methods;

3. Even for burners of the same brand, it is often the case that the installation area of the equipment accessories increases due to the limitations of the actual situation on the spot, which leads to the increase of the size and specifications of the sound insulation cover.

4. Affected by many factors such as the direction of the gas inlet pipe, the setting of the cable bridge, the height of the burner from the ground, the setting of the supporting steel frame, etc., the measurement of the soundproof cover of the burner should be different;

Therefore, the size of the opening position of the soundproof cover of the burner should be designed according to the site conditions and local conditions.

1. need to accumulate rich experience in actual measurement;

2. Find the best design ideas;

It is necessary to ensure the beautiful appearance of the product, but also to ensure that the air intake of the burner is not affected. The most important thing is to ensure the sound insulation effect of the product.

In order to better serve everyone, EPCB, based on many years of experience, will tell you the method of measuring customized sound insulation hoods for your reference in actual measurement and help you solve the problem of reducing noise in the boiler room.

However, this kind of measurement is also a measurement of approximate cost estimates. The actual measurement also needs to send professionals to the site to perform the measurement based on the actual situation.

Gas Boiler Burner Soundproof Cover Measurement Method

Let us briefly introduce the measurement method with reference to actual cases:

The front end of the burner is the length from front to back; the width from the left to the right of the burner is the width, and the height from the top of the burner to the ground is the height, so it is formed. The length X width X height (mm) is calculated in millimeters.

Note: Generally, some boiler panels are double-layered and a protective panel is added. The height measurement of this kind of boiler needs to measure the position of the outer chord of the arc. This can ensure the beauty and improve the sound insulation effect.

Some boilers are square, and the sound insulation cover of the burner will be very tight after installation. There is almost no opening position. The measurement of this equipment needs to solve the air intake according to the actual air intake requirements, fan heat dissipation, and bottom panel openings. The problem is that this kind of product measurement needs to calculate the size of the opening position based on the air intake of the burner. Accurate measurement is a key step in manufacturing a good product, and it must be taken seriously.

The above-mentioned methods are only one of them. Because the installation in actual work is various, these are all non-standard products, needs to be manufactured according to the measurement and design of the user's on-site installation.

What is the noise reduction effect of the boiler room?

After the above measures are taken:

1. The indoor noise measurement value of the residential area near the boiler room meets the national environmental protection category 1 area night noise emission standard, and the higher noise reduction is 28.5 decibels.

2. The human body can hardly feel the noise from the boiler room in every corner of the living room.

The design of sound insulation and noise reduction scheme for boiler room requires on-site noise investigation,Carry out targeted technical analysis of equipment installation location, sound source type, noise level and frequency, environmental/environmental protection requirements, ventilation and heat dissipation requirements, noise reduction targets, etc.

The design of the sound insulation and noise reduction plan of the boiler room requires on-site noise surveys to conduct targeted technical analysis on the installation location of the equipment, the type of sound source, noise level and frequency, environmental/environmental requirements, ventilation and heat dissipation requirements, and noise reduction targets.
