ABSTRACT:
A heating apparatus for the vaporization of a mixture of two liquefied gases in chemical equilibrium with a binary compound thereof includes a vertically disposed enclosed vessel having a lower liquid zone to which the mixture to be vaporized is supplied as a liquid from an external supply source and an upper vaporized gas zone from which gas can be removed for use. A vertically disposed heating element, which may be an electric heating element, steam tube, and the like, extends downwardly in the vessel through the vaporized gas zone and terminates above the portion of the liquid zone communicating with the liquid supply and is adapted to supply sufficient heat to vaporize a gaseous mixture from the liquid zone. A housing is disposed about the heating element in spaced relationship thereto and a heat transfer medium is contained within the space. The heating element is controlled by a control unit responsive to a thermal sensing element disposed in the interior of the housing and arranged to monitor the temperature of the portion of housing in contact with the vaporized gas zone.
