Refractory materials used in the glaze melting furnace Ⅱ

The furnace for melting glaze is small and shallow. The feeding port is always set on the sidewall. The bottom of the feeding port is 115mm higher than the tank bottom. The center of the feeding port should not be located in the intersection of the flame of the burner and the bottom. The size of the feeding port should be proper. If too big, the heat dissipating capacity will be big; if too small, the batching materials cannot be spread evenly. The feeding port is generally 300-350mm high and 400-450mm wide. 
 
Refractory materials used in the glaze melting furnace Ⅱ
The burner is provided on one end of the pool sidewall and the outlet of flame. The flame is ejected into the pool in a certain angle. The size of the inclination angle has a greater impact on the rate of melting.
 
If the flame is ejected horizontally or upward, the range of flame may be too far and the melting rate may be reduced; if the flame is ejected downward, it may cause incomplete combustion and uneven distribution of the temperature and easily blow away lighter components. 
The appropriate angle can make the flame just reach the surface of batching materials and make the temperature highest. 
 
In addition to adequate air, a certain combustions space is needed to achieve substantially complete combustion. The combustion space is the space composed of the bottom, sidewall and the lower crown. The size of the space should be appropriate. If it is too small, it may cause incomplete combustion which will affect the quality of glaze and waste of energy; if it is too big, it may make the temperature unstable and uneven and the flame cannot fill the entire space which will affect heat transfer and increase heat loss. The space volume of small glaze furnace is generally about 2.5-3.5m.
