Incinerator

Incinerators are a medium to long range flamethrower, appearing in the Fallout 3 add-on Broken Steel and Fallout: New Vegas.

Background
Heavy incinerators utilize the same practical technology as flamers but rather than spraying a cloud of flames in front of the wielder, the heavy incinerator spits out individual fireballs in rapid succession that have a very far effective range.
