Simulation on Flow Field and Temperature Field in Water Cooling Tuyere of Blast Furnace

Abstract:

Life span of water cooling tuyere is one of important factors of blast furnace’s direct motion and high yield. In order to improve the life of tuyere, the flow fleld and temperature field of tuyere were simulated by using computational fluid dynamics (CFD). Simulation results show that the maximum temperature appears at the front margin of tuyere outlet side. The highest temperature of tuyere reduces significantly with the increase of water pressure below 0.4MPa. When the water pressure exceeds 0.4Pa, the highest temperature reduces slowly. In consideration of economic benefit and cooling effect, the best point of inlet pressure is 0.4MPa or so.
