Burner ATMOS A 25 with actuator

Product detailed description

- for pellets, power: 4.5 – 24 kW

- is intended for boilers of type (high 3-chamber (3-door) boilers model 2018):

Boilers and burners DCxxSP and CxxSP in the Model 2018 version are equipped with the function of automatic closing or opening of the air supply to the boiler/burner using a servo motor when heating with wood or pellets. The boilers are equipped with a flue gas temperature sensor AGF2 and a boiler temperature sensor KTF20 for the function of automatic burner start after wood combustion is complete. They are also equipped with two sensors (TV and TS) KTF 20 for controlling the burner according to two temperatures on the storage tank. The complete set is therefore sold in maximum equipment for fully automatic operation and easy installation "plug and play".

- suitable for high-quality white pellets made from softwood without bark with a diameter of 6 - 8 mm, length of 10 - 25 mm and calorific value of 16 - 19 MJ/kg. An advantage of the burner is automatic fuel ignition using a heating coil, which ignites the pellets whenever heating is required. The burner and boiler thus operate at full power with the highest efficiency of 85 to 90% and the best combustion quality. Unlike many competing products, which do not have ignition devices and must always maintain a glowing layer in the combustion chamber.

Such low-power operation, where flue gas temperature drops below 100 °C, causes condensation of soot and acids in the combustion chamber and chimney. This results in lower efficiency, higher fuel consumption, worse combustion quality, greater boiler soot accumulation and more frequent cleaning. With our products, ash removal is performed every 7 to 30 days, depending on the fuel quality and boiler power. Burners are not intended for dark pellets.

If you want to burn lower quality wood pellets, equip the burner with a pneumatic cleaning system.

Ideal burner control is based on two sensors (TV and TS) on the buffer tank. The control unit fully automatically maintains the heating of the buffer tank and ensures sufficient energy for the heating system at all times. This method of connection will save fuel, electrical energy and increase the lifespan of the pellet burner.

The electronic control unit of the burner also controls the boiler exhaust fan, the pump in the boiler circuit and/or the solar system.

The electronic unit of the burner allows control of the burner operation using four sensors, so that if the sensor on the solar panel detects that it is advantageous to heat the buffer tank with energy from the solar collector, it ensures regulation of the burner charging the tank with energy from pellets only up to the level of the sensor TK (TS2), which is located in the tank between the sensors TS and TV.

The burner operation works as follows. If the burner receives a start command or a heating need arises, the conveyor feeds pellets into the burner throat and the heating coil ignites them automatically. After sufficient heating of the pellets, the burner reaches the set power and remains at this level until the system is heated. Then the burner turns off and the pellets in the burner chamber burn out. The entire cycle is repeated automatically in the case of further need. The boiler power and other burner functions are controlled by the electronic regulation of the burner, which allows the boiler operation to be adapted to specific conditions of the entire system.

The burner allows a large number of individual settings described in the operating manual.
