Background
Alcohol burners are used as a laboratory intensive heating instrument with flame temperatures up to 1000 ℃, and are commonly used for processing glass products. The traditional alcohol blast burner needs to be ignited and preheated before being used, so that the alcohol can be ignited for use after being gasified. However, in the way of using the alcohol burner after gasifying the alcohol, the alcohol burner is frequently extinguished, and the reliability of the alcohol burner is greatly influenced.
