Abstract

The invention relates to a method for producing mineral wool, wherein a mineral base material is melted in a cupola furnace having a shaft to hold the base material, the lower section of said shaft being provided with a grate, and beneath said grate there is a combustion chamber. The combustion chamber is heated by one or a plurality of burners, the burner or burners being run on liquid or gaseous fuel and an oxygen-containing gas. The burners are operated such that the length of the flames occurring during combustion of the fuel with the oxygen-containing gas is between 60% and 100% of the combustion chamber diameter.
