英文摘要: the overall goal of this proposal is to develop a novel approach of plasma-assisted porous combustion for organic waste gases degradation by experimental and theoretical method. The generation and distribution of discharge streamer in porous media for various conditions will be studied; the method of producing uniform stable discharge in the plasma-assisted combustion process will be obtained. The coupled mechanism of thermal effect, the radial generation and the exothermal reaction will be developed; the temperature distribution and temperature variation in the reactor, the discharge zone propagation in reactor will be investigated. The plasma and thermal effect of organic wastes degradation will also be studied, and their impacts on degradation efficiency and energy utilization efficiency will be estimated. The optimized parameters of degradation and energy utilization will be obtained. A better understanding of organic waste gases degradation by plasma-assisted porous media combustion will finally be provided.
