Abstract

For centuries dust explosions have been causing great damage to facilities and even lead to fatal incidents. The Chair of Thermo Process Technology at the Montan University Leoben is doing researches on this topic. The knowledge of how the flame front spreads in a dust-air mixture is necessary to develop safety devices. In order to measure the flame speed under low turbulent conditions, an apparatus was constructed at the department using the TUBE-Method. Inserting dust into the system is an essential part of the experiment. Trickling dust from above has proven itself due to its simplicity and high accuracy. The control variables of this process are an important feature for the reproducibility of the explosion tests. In the scope of this work, the dust-promoting stirrers were equipped with load cells and sensors. In addition, the entire system control and measuring electronics for the flame speed were programmed via LabVIEW. The control is carried out with the help of an Arduino Mega 2560, which was installed and wired together with other electronic components in a control box. The test facility was successfully commissioned.
