摘要

"A perpetual fire", which is characterized by a series of asbestos plates disks that superimposed form a limited cylinder in its two circular faces by an orifice metal plate; whose assembly is drilled in the longitudinal direction, carrying a wire or two that, when being twisted, serve as a fastening to the assembly and form a rod at the end of which it carries a plug, for its coupling and closure of the liquid combustion vessel that impregnates the cylinder.
