An experimental gasodynamic study of a model of furnace for ferroalloy production

A gasodynamic study of a model of hood space was performed based on measurements of velocity and concentration distributions of gases. The experiments have shown that the absolute values of gas velocities in the hood and the outlet channel as well as their profi les do not depend on the negative pressure value in the channel. Location of ceiling nozzle outlets does not signifi cantly aff ect the gasodynamic parameters of the hood space. Moreover, uniform distribution of the air, delivered through the ceiling nozzles, has been observed in the whole hood space, which creates conditions for afterburning of gaseous reaction products in this space.
