Impact of Pulverized Coal Preheating on Coal Combustion Behavior in Pulverized Coal Injection of Blast Furnace
煤粉预热对高炉喷吹中煤粉燃烧行为的影响

By establishing the mathematical model and using own program based on Fluent software,the combustion of pulverized coal injected at different preheated temperatures was simulated,and the impact of different preheated temperatures on coal burning was examined.The model contained the heterogeneous reactions of coal with oxygen,carbon dioxide and steam,and the burning reaction of coke was also considered.The size and shape of raceway were determined,and the coal combustion space was divided into four zones whi...
