Mandatory universal component of the fireplace is a smoke exhaust. This element provides absolute safety and more efficient operation of the heating system. Smoke exhausters for stoves and fireplaces efficiently and quickly remove harmful and hazardous smoke masses, which are formed during combustion and burning of fuel. This device allows you to organize the operation of the traction device.
Features of functioning
Regardless of the type of construction, all models for the most part have a similar structure and principle of operation. The main structural parts are a reliable and durable body, as well as an engine, which accounts for the bulk of the work. Of great importance are the guide and suction nozzles. The principle of operation of a smoke exhauster for a fireplace is that when cold air starts to flow from the room to the inside of the stove, it passes into the combustion chamber, where it is saturated with oxygen to the necessary degree. All this time, the wings of the smoke exhauster rotate vigorously at a set speed.
While fuel burns, the formation of smoke and combustion products. Using a traction device, they rise up the chimney, so they do not remain in the furnace and do not penetrate into the room itself. Since the impeller operates continuously, the air masses flow continuously. The fan a smoke exhaust for a fireplace is a kind of a peculiar amplifier of a chimney draft.
Benefits
The chimney fan is a smoke exhaust for the fireplace is needed in rooms where:
- the smell of burning is constantly present;
- narrow chimney flue;
- the chimney is too low.
This device perfectly solves these problems. In addition, this device has many other advantages:
- high power;
- profitability;
- resistant to the seasons and weather conditions;
- light weight;
- lack of noise;
- ease of installation;
- ease of further maintenance.
Thanks to this design, the life of the fireplace is extended. The operation of the smoke exhaust for the fireplace does not depend on the type of fuel.
disadvantages
This device also has disadvantages, one of which is the high cost. It should be noted that the fan will not work when there is a power outage. Then, in addition to stopping the provision of traction, the output of oxygen is difficult.
Varieties
There are two types of fans for the fireplace. A standard smoke exhaust with a vertical exhaust is a standard installation in homes. This variety is able to withstand temperatures above 210 degrees. Its power is enough to provide normal traction. Such a fan is equipped with several modes. This feature of it allows you to significantly save the consumption of electrical energy. So, for example, for the fireplace to work normally, it is enough to use the smoke exhauster at full power only until the time when the cold air is completely removed, then it needs to be switched to the saving mode.
More powerful is the horizontal fan outlet in the smoke exhaust for the fireplace. Such a device draws a burn after a strong fire, and then is able to function in normal mode. No additional maintenance is required. Due to the special design, soot and soot do not clog the system for a long time. It is noted that such a fan works properly at any time of the year, even in the most cold weather. Often for the sake of convenience, or following some other goals, people do not install an overall chimney system, but prefer do-it-yourself smoke exhausters for fireplaces.
Type of smoke exhauster
There is a special classification of roof fans for a fireplace. There are D type smoke exhausters, which are small appliances. In them, the wheel is located on the engine itself.
Another type of injection pump has the same design as the first option. However, the drive is more powerful, air intake is carried out by a one-way method, therefore it is possible to regulate the air supply. Such devices are more durable.
Electric smoke exhaust fan can have a different type of engine - centrifugal or axial. The main advantage of this device, which is powered by electric energy, is that it does not need to be installed permanently. DPE smoke exhauster is portable. This type of fan includes a trailed smoke exhaust (DP) and a fire engine (DPM). These designs are intended for fireplaces with a motor engine:
- centrifugal;
- axial;
- turbocharged.
Choosing a fireplace fan
Before buying a smoke exhaust, you need to pay attention to:
- the principle of the system;
- material reliability;
- functions.
Additional accessories should be purchased, namely special fasteners, protection against overheating and weather conditions. If all the components are selected correctly, then installing the system will be much easier, and the fireplace will work much longer. Choosing and purchasing this device, you should familiarize yourself with the temperatures of the warmed air masses and specifically the chimney. These devices can mainly operate at temperatures not exceeding 260 degrees. From time to time, the exhaust fan must be turned off to allow it to cool completely. The average duration of continuous operation is from 3 to 6 hours.
Today, a smoke exhauster for a fireplace is an indispensable attribute in every house where there is heating equipment. Despite the disadvantages present, the advantages of this device are much greater. Therefore, the purchase of such a fan can be considered as one of the best options for ridding air of combustion products.
