Boiler rooms make a lot of noise. They have many elements that make sounds: pumps, fans, pumps and other mechanisms. Basically, working in industry, with industrial equipment, one way or another forces the specialist to deal with noise, and there is no way to make the units completely silent yet. But you can make them much less loud.
How to reduce the noise of a boiler room when designing
Very strict requirements are imposed on the noise level of electrical and thermal power facilities, especially if the designated facilities are located within the city. A boiler room is just a heat power facility, and even being compact, it can cause significant discomfort to others.

Advantages and disadvantages of a mini-boiler room in an apartment building
Energy resources are becoming more expensive - this is a fact, so the issue of energy conservation has become especially acute lately. This also applies to heating systems apartment buildings. The cost directly depends on the method of supplying heat to residents, of which there are currently two: centralized and autonomous.
NOISE LEVEL
Sound intensity is measured in decibels (dB) in the frequency range from 31.5 to 16000 Hz and in the middle of each frequency band, i.e. at frequencies 31.5; 63; 125; 250 Hz, etc. A person perceives sound in the range from 63 to 800 Hz.
Sound intensity in dB is divided into levels A, B, C and D. Acceptable norm The overall noise level is considered to be level A, which is closest to the human sensitivity range. To denote this characteristic, we most commonly use the term “Sound Pressure Level”.
NOISE SOURCE
A running engine is a source of mechanical noise that originates in
gas distribution mechanism, fuel pump etc., as well as appearing in the combustion chambers as a result of vibration, air suction and fan operation, if installed. Typically, intake air and radiator noise is less than mechanical noise. If necessary, noise level data can be found in the Product Information Manual. You can reduce noise using sound-absorbing coating. If the mechanical noise is reduced to level 5 mentioned in the Noise Level section, you need to pay attention to the air and fan noise.
Effective and relatively cheap way- close the engine with a casing. At a distance of 1 m from the housing, the sound attenuation reaches 10 dB(A). Only specially designed housings are effective, so it is advisable to consult with specialists regarding its parameters.
If certain requirements are imposed on noise outside the premises in which the installations are located, the following conditions must be met:
1) Building design
External walls are made of double brick with
voids.
Windows - double glazing with distance
between glasses 200 mm.
Doors - double doors with vestibule or
single, with a screen wall opposite
doorway.
2) Ventilation
Fence openings fresh air and heated air outlets must be equipped with noise barriers. The Owner should discuss these issues with the Manufacturer.
Screens should not reduce the cross-section of the air ducts, as this will increase the resistance on the fan. Larger engines requiring more air require correspondingly larger baffles and the building must allow for proper installation.
3) Vibration-isolating mounts
Mounting the units on vibration-isolating supports prevents the transmission of vibration to walls, other installation components, etc. Vibration is often one of the causes of noise. (See anti-vibration mounts).
4) Exhaust muffling
It allows you to reduce noise by 30...35 dB(A) at a distance of 1 m from external wall premises, subject to the use of high-quality sound absorbers and exhaust mufflers at the inlet and outlet.
Soundproofing of a boiler room. In this publication we will look at the reasons higher level noise and vibrations from gas boilers and boiler rooms, as well as ways to eliminate them to achieve standard indicators and the level of comfort of residents.
The installation of autonomous modular gas boiler houses on the roofs of apartment buildings is becoming increasingly popular among developers. The advantages of such a boiler room are obvious. Among them
There is no need to erect a separate building for boiler room equipment
Reducing heat loss by 20% due to a small number of heating mains compared to heating from a central heating network
Savings on installation of communications from the coolant to the consumer
Absence of necessity forced ventilation
The ability to fully automate the system with a minimum of maintenance personnel
One of the disadvantages of a rooftop boiler room is vibrations from the boiler and pumps. As a rule, they are the result of shortcomings in the design, construction and installation of boiler room equipment. Therefore, responsibility for eliminating the increased noise level and measures for soundproofing the boiler room lies with the developer or housing management company.
The noise from the boiler room is low-frequency and is transmitted through the structural elements of the building directly from the source and through communications. Its intensity in a room equipped as a boiler room is 85-90 dB. Sound insulation of a roof boiler room is justified if it is done from the source side, and not in the apartment. Soundproofing the ceiling and walls in an apartment with such noise is expensive and ineffective.
Causes of increased noise levels in a roof boiler room.
Insufficient thickness and massiveness of the base on which the boiler room equipment stands. This leads to penetration airborne noise into apartments through the floor slab and technical floor.
Lack of proper vibration insulation of the boiler. In this case, vibrations are transmitted to the ceilings and walls, which emit sound into the apartments.
Rigid fastening of pipelines, communications and their supports is also a source of structural noise. Normally, pipes should pass through enclosing structures in an elastic sleeve, surrounded by a layer of sound-absorbing material.
Insufficient pipeline thickness as a design error leading to high speed water movement and the creation of an increased level of hydrodynamic noise.
Soundproofing of a roof boiler room. List of events.
Installation of vibration-isolating supports under boiler room equipment. Calculation of materials for vibration isolation is made taking into account the support area and weight of the equipment;
Elimination of “rigid connections” in places where pipeline supports are attached using strength meter material, thermal and sound insulation material or installation of vibration fastenings on studs fixing communications;
In the absence of elastic sleeves, the expansion of the passage of the pipeline through bearing structures, wrapping with an elastic material (k-flex, vibration stack, etc.) and a heat-resistant layer (basalt cardboard);
Wrapping the pipeline with a material that reduces heat loss and has sound insulation properties: Texaund 2ft AL;
Additional sound insulation of the enclosing structures of the roof boiler room;
Installation of rubber compensators to reduce the transmission of vibrations through the pipeline;
Installation of noise suppressors in the exhaust gas exhaust channel;
Installation of noise-absorbing materials based on basalt (Stopzvuk BP) or fiberglass (Acoustiline fiber) can reduce background noise in the boiler room by 3-5 dB.
SOUNDPROOFING A BOILER IN A WOODEN HOUSE.
Rules building codes And fire safety dictate the installation of the boiler in a special room equipped with a separate entrance. As a rule, it is located in the base or basement. With this arrangement, complaints about increased noise levels from the boiler are rare.
Boiler installed on the same floor with living rooms, which has high noise levels in complete silence in country house may cause inconvenience to residents. Therefore, soundproofing the boiler may be relevant.
The reasons for the increased noise level may be similar to those during the operation of a rooftop boiler room, but on a smaller scale. They are treated the same
Design features of the outer casing of the boiler. In most boiler models, the burner and fan are closed with a separate damper, which reduces the noise produced by the burner. If soundproofing protection is only plastic box boiler, the noise from the burner may be noticeable.
Noisy fan from the manufacturer.
Fan imbalance, dirt accumulation due to dust from outside and neglect of maintenance measures.
Air entering the heating system.
Incorrect setting gas burner.
Rigid mounting system for the boiler and outlet pipes.
Soundproofing a boiler begins with identifying the causes of increased noise levels and is associated with the work of the gas service employees servicing it or the company involved in soundproofing the premises.
If the boiler and system are working properly, then
We mount the boiler on a vibration-isolated platform on fastenings with a strength meter
Install rubber expansion joints where pipes exit from the boiler body
We purchase a soundproof casing for the boiler
We make additional sound insulation of the walls of the boiler room
