PURPOSE:To provide the titled such system that dust catchers resistant to high temperature is equipped on the way of dust-collecting ducts to remove nearly all of coke powder, thus mitigating the load on the dust collector at the end of the duct along with reducing the burning loss of collector filter. CONSTITUTION:Dust catchers 13, 18 are equipped on the integrated duct from the head collecting duct and bottom collecting duct in an extinguishing oven 1, and connecting, to said dust catchers, a coke dust blower 22 to an extinguishing oven pre-chamber 3, thus preventing a bag filter 25 in the dust collector 23 of the extinguishing oven from burning loss, and at the same time, attempting increase in heat recovery efficiency by blowing, into the pre-chamber 3 without using any conveying means, the coke powder collected and utilizing said powder.
