Effect of fuel combustion method on the convection and temperature fields in molten glass

In the melting end, the transverse convective flows bring the chemically active batch out towards the side walls of the tank and this causes accelerated corrosion of the upper row of bricks in the tank and leads to the need for premature maintenance of the furnace. The transverse convection in the glass also has a bad effect on the formation of the boundary of the layer of batch, helping to move it from the axis of the furnace towards the wall regions thus reducing the surface area of the batch and increasing the area of the open, clear surface of the glass. Since the temperature of the batch is significantly lower than that of the glass, the reduction in the surface area of the batch leads to a reduction in the intensity of heat exchange and the heat emission of the flame.
