Numerical Simulation Research On The Top Burner Of KALUGIN Hot Blast Stove

Kalugin hot blast stove is a top-combustion hot stove which was successfully designed by Russia companies. It was introduced and used by Jinan Steel Works, Laiwu Steel Works and Qingdao Steel Works in China and it demonstrates its unique superiority. Its successful application of these enterprises indicates there is a very wide application prospects. The specificity of the stove is in the Burner. The burning chamber of the burner are replaced by the vault. In the limited vault space the gas and the air are ignored and exhausted. So it is a excellent burner from the structure.In order to understand better about the burner of Kalugin hot blast Stove, in this paper by applying theκ-ε-f-g model of turbulent diffusion flame, 3-D numerical simulation of the combustion in the pre-burning chamber and the dome of Kalugin hot blast stove is carried out. The field of flow, temperature and components concentration distribution were obtained, and the shape of the flame in the dome was also gained. we draw a conclusion that tangential velocity of inlet stream is the survival key of Kalugin hot blast stove by analyzing the results.In addition, under the other conditions remain unchanged the different angel of tangential velocity were simulated, the different velocity of inlet stream were simulated, the state which the third inlet stream are turned to tangential stream from radial stream were simulated, the final simulated results may provide reference for the useful of top combustion hot blast stove.
