Features of the work and installation of pellet boilers

Despite being classified as solid fuel equipment, pellet boilers are far superior to conventional units that burn coal or firewood because

  • Dry pellets burn, giving much more heat, which significantly increases the efficiency of the unit;
  • In the process, a minimum amount of fuel combustion products is produced;
  • The pellet is loaded into the hopper is much less common than when using firewood or coal.

This effect is attained by using highly efficient pyrolysis combustion processes in conjunction with a unique equipment design. The fuel’s humidity level, which should be less than 20%, is crucial to the functioning of a pellet boiler. In the future, the equipment’s power will decrease and condensed moisture will enter the system if this requirement is not met. And this can quickly result in significant equipment malfunctions.

Combination pellet boilers are available that have two furnaces, one for burning pellets and the other for burning regular solid fuel. These units have a marginally lower efficiency than boilers that solely use pellets, and they still have fairly high installation and strapping requirements.

A bunker, burner, and screw mechanism for the pellet supply must be installed in addition to the pellet boiler. Experts frequently advise using a specific buffer container, whose capacity can be as high as 50 liters for every kW of pellet boiler power. The boiler room, where the equipment installation and strapping will take place, will now be substantially larger.

How to bind such equipment?

The following sequence of steps makes up the general plan for installing heating boilers:

  • installation of distribution combs;
  • Installation of the corresponding pumping circuits for each consumer;
  • installation of safety equipment;
  • installation of an expansion tank;
  • installation of shut -off valves;
  • Connection of the boiler with the supply and reverse contours;
  • filling the contours with a coolant;

In actuality, everything is dependent upon the equipment’s power, the quantity of users, the boiler’s design elements, etc. P. It should be mentioned that the strapping of pellet boilers is subject to some fairly strict regulations. First, because the fuel’s humidity should stay low enough, and second, because the coolant and fuel are both heated to extremely high temperatures. A substandard strapping material may cause equipment operating conditions to be breached, resulting in a premature failure of the boiler.

It is advised to strap pellet boilers using non-combustible metal pipelines in compliance with fire safety regulations. In practical applications, the utilization of polypropylene structures poses a risk and is not economically advantageous due to the coolant temperature at the boiler’s output frequently surpassing the operating indicators of polymer materials. This means that pipelines will need to be replaced after a few years.

The pellet boiler is an intricate device. Experts strongly advise against novices without experience installing and strapping these kinds of devices. Nonetheless, the work of the invited team of installers will be efficiently managed if they are aware of the key steps and subtleties involved in the strapping process.

One way to strap the pellet heating boiler is depicted in the diagram: 1 is the pump MK, 2 is the mixing crane MK, 3 is the pump TK1, and 4 is the mixing crane TK1. 5- TK1’s water recirculation; 6- TK2’s pump; 7 TK2’s mixing crane; eight-TK2 water recirculation; nine-DIS pump; Heat exchanger number 10 11- The hot water supply’s running water supply

What you need to bind the pellet boiler is:

  • install the boiler;
  • connect the appropriate burner (if the combined boiler model is used);
  • install a pellet hopper;
  • Connect a fuel jacket;
  • Connect the automatic control panel of the boiler.

Following that, you ought to complete:

  1. Installation of a safety group for a boiler, which includes a pressure gauge, an automatic air vent and a reset valve.
  2. Installation of a thermoclapan sensor, if this is provided by the design of the model;
  3. Installation of a chimney, the diameter and height of which meet the technical requirements.
  4. Installation of the system of devices to maintain the reverse flow: two taps-manometers for feed and return, circulation pump and thermalogram.
  5. With a high probability of sudden power outages, it is recommended to supplement the system with a suitable IBP model.

Up until the coolant is admitted into the system, you can regulate the amount of heating it experiences thanks to control flow support. The coolant will stay in the small circulation circle until the return temperature reaches the necessary level, which is typically 60 degrees or higher. The hot coolant will start to circulate in the main circle and the cold coolant will only start to arrive through it once the coolant has heated to the necessary level for the thermal head.

You should never use a pellet boiler with a coolant temperature that is too low. The term "dew point" refers to the temperature at which a sizable amount of condensate begins to form, which is 55 degrees. As a result, there may be a considerable buildup of soot on the heat exchanger and in the chimney. The equipment’s power will drastically drop and more maintenance work will be needed.

This is the appearance of the furnace chamber in a pellet heating boiler following exposure to an excessive amount of condensate, which results from mistakes made during the recirculation system’s installation.

The video shows the procedure for strapping the combined pellet boiler in detail:

A unique tank accumulator that enables you to store heat is something that many pellet boiler manufacturers advise adding to the structure. You can save up to 20–30% on fuel. Moreover, a drive tank ensures optimal efficiency by preventing the boiler from overheating.

A few words about the chimney

Good traction plays a major role in how effective the pellet boiler works. The chimney, when positioned properly, will offer enough traction in any wind and temperature of the air. First and foremost, it is important to keep in mind that the output pipe’s diameter and the chimney’s diameter should match. A condensate removal device must be installed in such a chimney. A properly installed cap won’t obstruct the pipe’s cross section or provide an aerodynamic support.

Two installation options for a chimney for a pellet heating boiler are shown in the photo. On the left, the incorrect option is displayed; on the right, the chimney is installed correctly.

Chimneys are usually made of metal pipes, which need to be properly insulated and have cleaning hatches. There should be at least 130 mm of lumen between the chimney’s outer surface and the components of the roof and ceiling. It should be kept in mind that too much traction and small size can be hazardous for pellet boilers. You will require a traction stabilizer or gate damper to solve this issue.
