Claims

[Claims for Utility Model Registration] (1) A crucible is disposed within a combustion chamber in which a burner of a furnace body is provided, and the burner has a passageway for guiding exhaust gas from the combustion chamber and a passageway for guiding combustion air from the burner. A metal melting furnace characterized in that the two are separated by a heat transfer wall. (2) A partition member that surrounds the crucible and forms the combustion chamber is disposed in the furnace body, and the partition member allows exhaust gas to be reversed from the bottom of the combustion chamber and formed radially outward of the partition member. The first utility model registration claim is characterized in that the combustion air is guided through an exhaust gas passage, the burner faces the combustion chamber, and the combustion air is preheated by the exhaust gas from the exhaust gas passage. Metal melting furnace as described in section.
