Numerical investigation of influence thermal preparation coal on nitric oxides formation in combustion process

摘要：

Emissions of nitrogen oxides from coal combustion are a major environmental problem because they have been shown to contribute to the formation of acid rain and photochemical smog.Coal thermalpreparation before furnace delivery is effective method to reduce NOx emissions,shown by experiments in small-scale facilities 1.This paper presents the mathematical model of burning thermal preparation coal.Validation of the model was carried out on laboratory-scale plant of All-Russia thermal engineering institute.Modeling of low-emissive burner ,with preliminary heating coal dust is made for the purpose of ,search of burner optimal constructions which provides low concentration of nitric oxides in the boiler.For modeling are used in-house CFD code <oFlow>2.
