一、高炉内的欧根公式欧根(ergun)通过对汽体通过散料层时阻力损失的研究,给出了如下公式: (△P)/L=150(μW(1-ε)~2)/((d_pφ)~2ε~3)+1.75(1-ε)/ε~3×ρW~2/(d_pφ) (1)式中 (△P)/L——散料层的压力降梯度,公斤/米~3;W——气体的空气流速,米/秒;d_p——球形散料颗粒直径,米;ρ——气体密度,公斤/米~3;ε——散料的空隙率;φ——颗粒散料的形状系数;μ——气体粘度,公斤/秒·米。
First, the Eugen formula in the blast furnace Eugen (ergun) by the resistance of the body through the bulk layer when the loss of resistance is given the following formula: (△ P) / L = 150 (μW (1-ε) ~ 2 ) / (d_pφ) ~ 2ε ~ 3) +1.75 (1-ε) / ε ~ 3 × ρW ~ 2 / (d_pφ) (1) where ΔP / L is the pressure gradient , Kg / m ~ 3; W - gas air flow rate, m / s; d_p-- spherical bulk material particle diameter, m; ρ - gas density, kg / ; φ - particle bulk material shape factor; μ - gas viscosity, kg / s · m.
