Research on the Reasonable Air Velocity of Blast Furnace Tuyere

Abstract:

Researching on the influence of blast furnace tuyere under the condition of hot gas flow rate range of 60 ~240m / s by the method of using computational fluid dynamics. During the process of going through the tuyere, the tuyere cool the hot gas due to the cooling water inner it . At the same time, the more slow hot gas flow velocity is, the stronger cooling effect is, the greater energy is lost. Take this to hot air flow field of three dimensional numerical simulation, and discussed the reasonable air velocity interval, which can guarantee low thermal load and prevent a loss to larger energy .
