2D Modelling and Simulation of Heat Transfer in Blast Furnace Hearth Using ANSYS
Iron blast furnace is used in the metallurgical field to extract molten pig iron from its ore through a reduction mechanism. Hearth is the most important part to find life of furnace. Campaign life of furnace is reduced due to erosion of refractory line. Temperature inside the blast furnace is very high and practically observe these process inside the hearth is very difficult. In order to overcome this problem, the hearth is modelled by using various computational fluid dynamics (CFD) softwares such as ANSYS Fluent, ANSYS-CFX, FLUENT. The numerical model is then supplied with data which are already known from practical situations as boundary conditions. Materials’ proper physical properties are also used as input. The software runs several simulations and provides us with the result that can validate the experimental observations up to the most accurate level. In this study, temperature distribution profile inside a blast furnace hearth has been shown by modelling a simple hearth with the help of ANSYS 15.0 Workbench.
