A Numerical Simulation of Flow Field and Temperature in Water Cooled Tuyere

QIE Ya-na;ZHANG Shu-hui;L Qing;Metallurgy and Energy School,Hebei United University;  
Reasonable temperature field and flow field of tuyere in blast furnace is very important to tuyere service life. The flow field and temperature field of tuyere were simulated by using computational fluid dynamics( CFD). Simulation results show that the front edge of the tuyere outlet side has the highest temperature. Improving the water pressure when the pressure of the inlets below 0. 4 MPa,the flow velocity will increase,while the peak temperature of the tuyere front-end will obviously decreases. However,the situation result is reverse when the inlet pressure exceeding 0. 4 MPa. Comprehensive consideration,when the inlet pressure is about 0. 4 MPa,the highest temperature is low and the cooling effect is obvious.
