Experimental Study on NO_x Emission of Pulverized Coal Combustion in

摘要

This thesis summarizes the whole bag of tricks of controlling CO_2 in power plant, and describes in detail the technologies and prospects of O_2/CO_2 combustion. The mechanisms of NO_x reaction and reduction have been studied systemically. Based on the system of Entrained Flow Reactor, a series of experiments on emissions of NO_x in O_2/CO_2 combustion technology are carried out. According to the datum, the emission characteristic of NO_x under different medium, initial oxygen concentration, 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 O_2/CO_2 combustion technology.
