ABSTRACT:
A runner for hot metal as from a blast furnace is formed of a series of interconnected modular units which are prefabricated, preferably from consumable, combustible and/or disintegratable materials of desired densities. A plurality of tunnel-like refractory lined covers are positioned continuously of the runner formed of the interconnected modular units so as to confine fumes, gas, smoke and other air pollutants. Vacuum devices are in communication with the covers so as to remove the air pollutants from the same and direct them through scrubbers and/or precipitron equipment to remove the air pollutants before the air entrained in the system is released to atmosphere.
