BURNER: CATALYTIC COMBUSTION BURNER WITH A SPECIAL TIP AND EQUIPPED FLASK OF SUCH A BURNER

摘要

The catalytic combustion burner comprises a tip (1) made of porous material with a frontal wall (2) and a peripheral wall (3) delimiting together a cavity (4) extending the length of a principal axis (5), with this tip being intended for covering a higher extremity of a fuse engaged in the cavity according to an initial direction (7) and appropriate for the soaking up the tip of a combustible composition. A circular groove (11) is dug in the tip following direction that is the inverse of the first, with the peripheral having an external lateral face (12) at least part of which is doped by a catalyzer, and with the central area of the upper face being free of catalyzer. According to the invention, the groove is delimited by the lateral faces (13a, 13b) sloped with respect to the principal axis, with each one diverging following the initial direction.
