CONT

Vertical rotary burners consist of two type: the wall-flame burner and the sunflower-flame burner. ... The sunflower-flame type is a straight high-speed centrifugal atomizer, as is the horizontal rotary. ... This burner was a costly, though finely made, device, and the advent of less costly and simpler burners has resulted in its discontinuance.

OBS

Vertical rotary centrifugal atomizers stand vertically within the boiler or furnace, and the flame has the appearance of a giant sunflower. They spin the oil from a cup or from between disks that are rotating at a speed of anywhere from 3,450 to 12,000 rpm. Vertical rotary burners do not use a combustion chamber because of the manner in which they are installed within the boiler or furnace. Instead they use a circular hearth, ... the characteristic parts of these burners are their cups and high-speed motors, in addition to float valves or other devices used to maintain a constant flow of oil.

OBS

Le brûleurs à axe vertical se différencie de ceux que nous avons décrits précédemment [...] la vaporisation rapide du liquide ainsi que l'effet ascensionnel qui résulte de l'élévation considérable de la température, fait que le mélange de gaz se déplace selon une trajectoire F nettement incurvée vers le haut de la chambre de combustion; on obtient de cette façon une flamme globulaire en forme de tulipe [...].

OBS

[...] certains brûleurs américains [...] produisaient des flammes "tulipes" de faible volume.
