Provided is a glass melting furnace for use in an apparatus and process for producing a molten glass by melting batch material particles for glass and cullet pieces, the furnace being capable of maintaining the homogeneity of the molten glass. Batch material particles for glass are dropped from batch material particle heating units (14) comprising oxygen burners (34, 34, ···) and batch material particle introduction parts, and the batch material particles are turned into liquid glass particles (38, 38, ···) in a high-temperature gas phase due to flames (32, 32, ···) from the oxygen burners (34, 34). When the batch material particles are heated and melted, cullet pieces (30, 30, ···) are introduced radially through an introduction means (40) of a cullet piece introduction part (12) toward the multiple flames (32, 32, ···) located therearound. Cette invention concerne un four de fusion du verre utilisé dans un appareil et un procédé de production d'un verre fondu en faisant fondre des particules de matière en lot et des rognures, le four étant capable de maintenir l'homogénéité du verre fondu. Les particules de matière en lot proviennent d'unités de chauffage desdites particules (14) comprenant des brûleurs d'oxygène (34, 34, ···) et des éléments d'introduction des particules, les particules de matière en lot étant transformées en particules de verre liquide (38, 38, ···) dans une phase gazeuse à température élevée à cause des flammes (32, 32, ···) des brûleurs d'oxygène (34, 34). Lorsque les particules de matière en lot sont chauffées et fondues, les rognures (30, 30, ···) sont introduites radialement par un système d'introduction (40) d'un élément d'introduction de rognures (12) en direction des nombreuses flammes (32, 32, ···) situées autour.
