| Abstract: | With the help of CFD(computational fluid dynamics) software Fluent and by choosing a rational mathematical model,a numerical simulation was performed of a 600 MW ultra-supercritical wall-type-arranged tangentially-fired boiler.The influence of the aerodynamic field,temperature field,component field and different SOFA(separated over-fired air) air ratios on the NOx generation and flue gas constituent characteristics of the boiler in question were mainly studied.The research results show that the in-furnace t... |
