Abstract
Abstract A connection device for connecting between the flue conduit extending from a combustion furnace or reactor and a washingabsorption tower which concurrently serves as high temperature gas quenching means comprising a double-walled structure which includes an inner porous cylinder and an outer impervious cylinder surrounding the inner cylinder in a peripherally spaced relationship thereto, a cooling liquid inlet means in said outer cylinder, a water-proof porous annular plate member provided between said flue conduit and double-walled cylindrical structure and gas inlet means adjacent to said water-proof porous annular plate member.
