Numerical simulation in combustion space of an oil fired float glass furnace

To reduce energy consumption and prolong furnace life, numerical simulation in the combustion space of an oil fired float glass furnace was carried out. The gas phase is expressed with k-epsiv two-equation model; the combustion is described with non-premixed model; the oil drop motion is described with Discrete Phase Model; the radiation is expressed with Discrete Ordinates Radiation Model. The simulation results agree well with the actual industry data. The results show that the flame covers widely and uniformly with a thin stagnation flow layer near the glass surface, being beneficial for melting glass melt effectually; there are back flows occurring near the crown, being beneficial for decreasing the crown heat duty.
