PROBLEM TO BE SOLVED: To provide a melting furnace that can melt a melting object with high-heat efficiency while generating a homogeneous and fine melting product material by preferably convecting melting object in a dissolver.SOLUTION: A melting furnace includes: a combustion device N for heating a melting object G loaded into a dissolver 11 with a flame K formed in a combustion space S in an upper part of the dissolver 11; a gas injection hole 30a for injecting a gas into the melting object G loaded into the dissolver 11; and a premixed gas introduction mechanism for leading a premixed gas premixed an oxygen-containing gas A with a fuel gas F with an air ratio within a combustible range into the gas injection hole 30a.SELECTED DRAWING: Figure 1 【課題】溶解槽の溶解対象物を良好に対流させて均質で清澄な溶解生成物を生成しながらも、高い熱効率で溶解対象物を溶解できる溶解炉を提供する。【解決手段】溶解槽１１に投入された溶解対象物Ｇを溶解槽１１上部の燃焼空間Ｓに形成する火炎Ｋにより加熱する燃焼装置Ｎを備え、溶解槽１１に投入された溶解対象物Ｇの内部へ気体を噴出する気体噴出孔３０ａを備え、酸素含有ガスＡと燃料ガスＦとを可燃範囲の空気比で予混合した予混合ガスを気体噴出孔３０ａへ導く予混合ガス導入機構を備える。【選択図】図１
