Evaluation of the dust potential hazard of thermal power plants through coal dust combustion and explosion characteristics
Thermal power is the main source of electricity in Taiwan, where coal is the primary fuel. However, concerns for potential fire and explosion hazards caused by coal dust are increasing. The problem regarding the storage or transportation process of coal cannot be neglected. This study explored four...
