Reducing the Power Consumption of Ventilation Systems Through Forced Recirculation

Abstract

A method of reducing dust emission and the power consumption of a ventilation system by improving the management of forced delivery of recirculated air to the charging trough is proposed. A portion of the ventilated air is fed to the charging trough, which tends to reduce the volumes of ejected air entrained by the stream of free-flowing material. The influence of the geometric parameters and the flow rate of the recirculated jet on the volume of discharged air are investigated by means of computer modeling.
