| Abstract: | With the CFD(computational fluid dynamics)software FLUENT,numerical simulation was made in a 600,MW ultra supercritical wall-tangentially fired boiler.The distribution characteristics of fuel NO,thermal NO and total NO in the furnace were analyzed in detail under the condition of deep air staged combustion,and the production characteristics of NO and HCN at the beginning of combustion were also studied.The result shows that a large amount of fuel NO is formed at the stage of evaporation.Homogenous subtracti... |
