Title:
HYDROGEN-FLAME COLORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208746
Kind Code:
A1
Abstract:
The present invention can excellently color a transparent hydrogen flame with high brightness, and can maintain a color developed state of the hydrogen flame for a long time period. The present invention is provided with: a plurality of burners (21) that generate a hydrogen flame (F) by burning hydrogen; and a coloring part (31) disposed at a position toward which the hydrogen flame (F) is generated from flame ports (21a) of the burners (21). The coloring part (31) is formed of color developing members (32) and through portions (33) through which the hydrogen flame (F) passes. The color developing members (32) are each formed by causing a porous body (32b) made of aggregated lava to carry a color developing material (32a) which gives a flame reaction. The through portions (33) are formed at spaces generated among the arranged color developing members (32).
