A process for preparing and fining a glass melt in a glass melting tank and corresponding glass melting tank

In a method for the production and refining of a glass melt in a glass melting furnace of the glass melting tank is supplied with a mixture, transferred to the mixture under heat in the glass melting furnace in the molten glass and to generate heat in the glass melting furnace above the glass melt fuel under air and / or oxygen supply burned. In order to improve the thermal conditions within the glass melting furnace, it is proposed that introduced as fuel wood dust in the existing above the glass melt combustion chamber of the glass melting furnace and is burned there under air and / or oxygen supply.
