Turbocharged gas boiler and what it is: the principle of operation - Setafi

It is not difficult to understand what a turbocharged gas boiler is when compared with an atmospheric installation. In the latter case, the thrust is natural, and the turbocharged equipment is equipped with a pump. It provides forced draft, due to which the combustion process is more complete. The features of the device, the pros and cons of such models are described in detail in the presented material.

Description and arrangement of a turbocharged boiler

To understand what is the peculiarity of this equipment, you need to get acquainted with the classification of boilers into 2 types:

1. Atmospheric (installation of an open type) - burns fuel due to oxygen, which comes from the environment. Moreover, the air flows without coercion, due to natural draft.
2. Turbocharged (closed type) also burns fuel, but due to forced air flow. It is carried out with the help of a fan. We can say about a turbocharged gas boiler that this is a device that runs on traction and therefore gives more heat.

The device consists of a closed chamber and a heat exchanger. A burner is installed here, as well as a gas model and a secondary pump. The inflow of air and the removal of gases and other combustion products is provided by a circulation pump powered by electricity. You can clearly understand what a turbocharged boiler is using the diagram below.

The main types, pros and cons of the boiler

A turbocharged boiler is used to heat residential premises of various sizes, including houses with several floors. This is explained by the fact that due to the influx of air, the gas burns almost completely and gives more heat.

Depending on the functionality, there are 2 types of turbocharged pump:

1. With one circuit - used only for heating.
2. With two circuits - used for both heating and hot water supply.

There is also a classification related to the number of nozzles:

1. With a single one (there are 2 pipes of different diameters, they are inserted into each other - a coaxial chimney is obtained).
2. With two separate pipes.

Finally, if we consider the division by location, we can note 2 classes of boilers:

• floor;
• wall.

Regardless of the features of the device, a turbocharged gas boiler has several advantages:

• it is safe because air is taken from the environment, and combustion products are forcibly removed to the outside;
• the fuel burns completely - the maximum possible amount of heat is generated (high efficiency);
• there is no need to make a separate chimney, because it is already provided in the boiler equipment;
• works almost silently;
• dimensions are usually small - it does not take up much space;
• The chimney system is compact, easy to install, and light in weight.

There are no shortcomings in this equipment as such. But it should be understood that turbocharged boilers are more expensive than atmospheric ones. In addition, they depend on electricity, because the circulation pump is powered by the mains. If power outages are common in rural areas, it is better to purchase a classic natural draft boiler.
