Abstract

Oxy-fuel combustion is an important development direction of combustion technology, and the key technology to reduce the cost of flue gas purification is the reduction of denitration cost. Based on the experiments and simulation process with Aspen Plus of pressure denitrification process, the reaction time and equilibrium concentration were analyzed when the denitrification reaction was balanced. Finally, the denitrification process was optimized according to the simulation results. The results showed that the equilibrium concentration and time of the denitrification process decreased with the increase of pressure, initial oxygen content and the decrease of temperature. The content of NO in flue gas had little influence on equilibrium concentration and time. After analysis and calculation, it is considered that 30? and 26bar is more suitable for denitrification process of the pressurized flue gas.
