PER OPERATION OF THE AUTOMATIC HEAT SOURCE ON PELLETS WITH VARIOUS BURNER TYPES

Abstract

One of the most important issues in choosing a heating system is the question: What kind of fuel can be burned in given heating system. Modern automatic solid fuel boilers are often specialized only on a narrow range of suitable pellet materials. Pellets from cheaper sources are also beginning to appear on the market. However, many burners are unable to burn these new types of pellets without significant burning problems. The article deals with the influence of the proper construction of the burner on the smoothness of the combustion process and the smooth operation of the combustion equipment. The results of the experiments document the continuity of the combustion plant in the combustion of less quality pellets containing bark using more modern combustion technologies. In fact, less quality pellets cause the formation of ash sinters which cause the continuous combustion process to be interrupted, resulting in fluctuations in equipment performance and the onset of thermal discomfort. The results showed no problem with burning even when making sinters, but also showed a fluctuation in performance and the need for manual control, especially when heating or clogging the supply pipe. They also showed significant damage to pellets in the worm feeder section. These problems, therefore, ultimately require further research to ensure complete, seamless operation.
