| Zusammenfassung: | The thesis presents an overall model of the mechanism of dust explosions. The ignition process of a dust explosion in general is defined by the balance of the rate of heat production and the rate of heat loss to the surroundings. Ignition parameters such as the minimum ignition energy, the minimum ignition temperature and the maximum experimental safe gap can be derived by using this balance. However, very small ignition volumes, smaller than the critical ignition kernel, need extra energy to ignite. Burning dust clouds with volumes smaller than this critical ignition kernel can not initiate a dust explosion. A unique laser ignition method has been applied to determine the kinetic data of the ignition reaction and to study the phenomenon of the critical ignition kernel. To better test the correctness of the dust explosion propagation theory, a high pressure, high temperature explosion bomb has been built. This apparatus allows study of the propagation of dust explosion at high temperatures, high pressures, high levels of turbulence and extreme stoichiometric conditions. |
