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 refractory based materials. A plurality of flat slab-like covers are positioned continuously on the runners formed of the interconnected modular units so as to confine fumes, gas, smoke and other air pollutants. Live steam is introduced at selected locations along the runners to collect, absorb and mix with the fumes, gases and air pollutants. Vacuum devices in communication with the covered runners remove the air, steam and pollutants and direct them through scrubbers and/or precipitron equipment to remove the air pollutants before the air entrained in the system is released to the atmosphere.
