Paperback. Condición: New. Print on Demand. In this analysis of coal dust's flammability, the author investigates the conditions that determine the likelihood of a coal dust explosion. Through a meticulous series of experiments, the author establishes a scale for categorizing the relative combustibility of coal dust from different sources. Detailed graphs illustrate the progression of each experiment, aiding the reader in understanding the process and its results. The work not only provides a valuable tool for evaluating the fire risk associated with coal dust, but also enriches our theoretical understanding of the combustion process.
