Heating with boilers with pellets
The main and very important difference between the heating water boiler with pellets and the solid fuel boiler is rooted in the way the combustion process is done. The electronic control in the pellet systems is crucial for the efficient combustion, such as software and controller have an essential role. In general solid fuel boiler in the combustion chamber there is a low resistance inside and free access to oxygen. The temperature in the combustion chamber varies between 230-250⁰ C, and the temperature in the chimney is 130-150⁰ C. This means that the transferred heat to the water jacket is on average 100⁰ C. The residue is lost in the air. This is why this type of equipment to achieve in practice, efficiency 60-70%. In boilers of pellets we have automatic control over the process of filing and giving oxygen to the combustion chamber and giving it to the chimney. Thus the facility maintains a high internal resistance and minimal traction in the chimney, which "prevents" the heat to leave the combustion chamber. Thus the temperature in the combustion chamber reaches 350⁰ C, and the temperature of exhaust gases in the chimney is in the range 80-100⁰ C. That is to say, more than 250⁰ C heat to the water jacket and a much higher efficiency to 93%.
There are more pros in the described above combustion technology. Because the pellet boiler itself is the "heart" of the heating system, it adapts automatically to the needs of consumers. What does it mean? At any time, the facility generates just as much heat as it is needed. Desired heat is determined by the user through manual control over thermal heads and room thermostats or by selecting the programs and settings of the electronic control panel of the boiler. Modern solutions include modules for remote control with a mobile phone and the Internet.
