用前炉。[Scope of Claim for Utility Model Registration] In a forehearth for feeding molten glass melted in a glass melting furnace to a supply furnace, a hanging wall portion is provided in the length direction of the central part of the ceiling of a furnace body block constituting the forehearth. A right-hand chamber and a left-hand chamber are formed on both sides of the hanging wall, and each ceiling of the right-hand chamber and left-hand chamber has a wall oriented substantially perpendicularly to the surface of the molten glass flowing through the furnace. A heating burner and an exhaust gas section from which the combustion products of the burner are discharged are arranged at appropriate intervals, and cooling holes are formed in the hanging wall section upward from the bottom surface thereof. A forehearth for molten glass, characterized in that the cooling hole is in contact with a cooling air passage via a heat sink.
