Abstract

Melting glass requires large amounts of energy, representing 15% of manufacturing cost for industrial producers. Melting glass furnaces’ primary source of energy is natural gas. Inefficiencies in furnaces cause energy consumption per ton of glass to range from 3.8 to 20 mm Btu. The majority, 70%, of the energy used to produce glass is for smelting and refining of the glass. The high inefficiencies cause 60% of the energy consumed for smelting and refining to be lost to the atmosphere. This represents a large amount of waste, 6.3% of total manufacturing cost. The rising cost of natural gas is expected to increase the fuel cost proportion of total manufacturing cost and decrees the competitiveness of glass producers. Thus there is a need for minimizing this amount of energy that is wasted. The development and verification of an innovative modeling technique for industrial gas fired glass melting furnaces will be discussed. Rapid and accurate modeling of industrial furnaces is needed for the development of advanced furnace control systems. Although, computational fluid dynamics modeling of industrial furnaces has been shown to be accurate, they are computational expensive. The CFD simulation match with information obtained via CCD camera for calculation heat exchange within the furnace. The calculated heat flux to the glass using turbulence and species model is in close agreement with the CFD model. It is also observed wall heat loss during combustion.
