[0002] A glass kiln is a thermal equipment used to melt glass batch materials in glass manufacturing.

The rising pipe 105 is connected with the conveying pipe 104, and is integrally formed with the conveying pipe 104, and is located on the upper right side of the conveying pipe 104. A liquid outlet 109 is set at the top of the right side of the rising pipe 105.
