A New Method to Optimize Furnace Designs Using Daily Flow Rates to Maximize Energy Savings in the Steady Production
Fluid dynamic simulations within a float glass furnace model with a variable siege height were performed by using the FLOTRAN module within an ANSYS software package. Steady circulatory patterns of glass fluid are established and identified in various regions of the furnace, and corresponding daily flow rates within the furnace were calculated. By increasing the siege height, the region of bottom backward flow was found to have decreased at the waist and working chamber. For a typical siege height of 0.3 m, the furnace required 5.39 × 1010 J/day less energy to reheat the glass fluids, as compared with a traditional siege height.
