Alcohol flake flame burner

The utility model provides an alcohol flake flame burner, which belongs to the technical field of combustion diagnosis and comprises a bottle body, a separated bottle cap is arranged at the upper end of the bottle body in a matched manner, and a plurality of separated sleeves are vertically arranged at the upper end of the bottle cap. The distance between every two adjacent sleeves enables adjacent flames to be in a fused state, and the phenomena of container temperature rise and alcohol boiling caused by long-time ignition are avoided. Combustion inner cores are arranged in the sleeves. The upper end of the burning inner core protrudes out of the upper end of the sleeve, the lower end of the burning inner core extends to the bottom of the bottle body, and a transparent outer cover is arranged on the outer side of the bottle body. The device is used for experiments of interaction between femtosecond laser filamentation and flame, and meets the requirement of full interaction between all positions of the laser
