Experimental Study And Mechanism Discuss Of NO_x Emission Characteristic In O₂/CO₂ Combustion Technology

This thesis summarizes the whole bag of tricks of controlling CO2 in power plant, and describes in detail the technologies and prospects of O2/CO2 combustion. The mechanisms of NOx reaction and reduction have been studied systemically. Based on the system of Entrained Flow Reactor, a series of experiments on emissions of NOx in O2/CO2 combustion technology are carried out. According to the datum,the emission characteristic of NOx under different medium, initial oxygen concentration, excess air coefficient, reaction temperature, reaction times and coals has been analyzed. The disciplines summarized from the experiments are significative for the theory and technology. It provides reliable reference for optimizing the emission characteristic in O2/CO2 combustion technology.
