Abstract:
A method for carrying out combustion in a glass melting furnace having a porous roof comprising:a) providing a combustion zone containing an atmosphere of furnace gases; b) providing a charge on the bottom of the furnace; c) injecting a low velocity oxidant stream through at least one oxidant injection side of the porous roof into the combustion zone at a flow rate of less than 600 SCFH/ft2; d) injecting a second source of oxidant through a lower portion of a sidewall and creating an oxygen rich zone between the combustion zone and the charge; e) injecting a fuel stream through at least one fuel injection side; f) mixing the low velocity oxidant, the second source of oxygen and fuel stream in the combustion zone to create a flame with reduced temperature.
