Description

Technical Field

[0001] The utility model relates to the technical field of external heat insulation of alcohol burners, and specifically relates to an external heat insulation component for an alcohol burner. Background Technique

[0002] An alcohol burner is a commonly used instrument for enhancing heat in a laboratory. Its flame temperature can reach about 1000 °C, and it is particularly suitable for experiments that require high temperatures such as the processing of glass instruments. The working principle of an alcohol burner is based on the mixed combustion of alcohol vapor and air. The heat generated by the combustion of ethanol in the preheating disk heats the ethanol rising along the wick in the preheating tube, causing a large amount of it to vaporize. Since there is no air in the preheating tube, the ethanol vapor gasified by high temperature cannot burn. Therefore, under the drive of pressure, the ethanol vapor is sprayed into the spray tube from the nozzle and mixes with air in the spray tube, and starts to burn after being ignited. The heat conduction performance of the burner enables once it is ignited, the temperature of the flame at the nozzle of the burner is sufficient to maintain the continuous vaporization of ethanol and enter the spray tube through the nozzle, thereby maintaining combustion.

[0003] However, traditional alcohol burners have no protective measures and are prone to burns caused by accidental contact during use. Therefore, technicians in this field have provided an external heat insulation component for an alcohol burner to solve the problems raised in the above background technique.
