Abstract
A method and an apparatus for cooling blast furnace gas for use in a blast furnace gas treating system having incorporated therein a coarse particle removing unit having a dust collecting box. Nozzles extend through the box as arranged circumferentially thereof at a plurality of locations for injecting a cooling fluid into the unit without wetting the inner wall thereof. Since the unit which has a large capacity is used also as a cooling container, a large quantity of cooling fluid can be injected to effectively cool the blast furnace gas even when the gas has a considerably high temperature. The system can be constructed at a low cost without necessitating any additional cooling container.
