Поширені поломки твердопаливних котлів
No matter how expensive and efficient the equipment is, it can break down over time. To understand that the heating equipment is out of order, you need to know the main malfunctions of solid fuel boilers and the reasons that caused them.
A solid fuel boiler will heat up until the safety valve is triggered by boiling water inside the system. In most cases, the boiler overheats due to an emergency power outage. To prevent this, it is recommended to install an uninterruptible power supply and a storage tank (heat accumulator).
To prevent such a trouble, it is important to ensure that the water temperature in the return pipeline is not lower than 55 degrees. For this purpose, a three-way mixing valve is installed.
Solid fuel boiler overheats
Why does the boiler temperature rise to too high values? This can happen for various reasons. For example, due to a breakdown of the circulation pump or if the equipment is selected incorrectly, so the heat generated by the boiler is much more than necessary to heat the room.
Condensation from the boiler or chimney
The reason may be insufficient temperature of the coolant in the return pipe if the solid fuel boiler does not reach the temperature. If this malfunction is not eliminated, soot begins to accumulate in the chimney. The service life of the equipment is also reduced.
Resin formation on the walls of the boiler
The cause of resin contamination of the heat exchanger can be:use of low-quality fuel;
The most common causes of tar formation on the boiler walls are improper installation and improperly selected fuel.
Poorly burning fuel in the boiler
If a solid fuel boiler burns poorly and the fuel in it does not completely burn, it is necessary to check the draft in the chimney and, if necessary, clean the equipment. The reason why a solid fuel boiler does not burn may be the lack of draft. Therefore, if cleaning the pipe did not help, you need to increase the height or cross-section of the chimney pipe.
Pressure rises strongly
The pressure in the system may rise because the expansion tank used has insufficient volume or is damaged.
Black smoke is coming from the boiler
The reason why black smoke comes from the pipe may be the use of low-quality fuel or insufficient air to ensure high-quality combustion.
Too much fuel consumption
Excessive fuel consumption may be due to its poor quality. For example, it has minimal calories or high humidity. Other reasons for high consumption include:- significant heat loss of the room;
- incorrect choice of boiler power;
- errors in the design of the heating system.
