Abstract
The vaporizer is connected to a liquid out let of the propane supply tank. The liquid propane flows to High pressure regulator which reduces the pressure to 50 psig. By reducing the pressure of the liquid.
the enthalpy of the liquid vaporizes about 12% of the propane and the temperature of the liquid propane is reduced to 20 degrees F. The propane then flows through a helical coil which is immersed in water with antifreeze which is heated by propane vapor burner. The bath transfers heat to helical coil which vaporizes the balance of liquid propane. The vapor outlet is then reduced with a regulator The the vaporizer is equipped with pressure switch control the pressure and would shut off the Bruner if the pressure went to high. This could happen if the vapor demand exceeded the capacity Of the vaporizer.

Description
_ Background of the Invention 1. Field of the Invention This invention relates to a vaporizer that supplies heat to liquid L.P. gas.
(T o turn one imperial gal. of propane to vapor takes approx.. 1,000 B.T.U.$) to supply vapour propane for devise that Utilize vapor propane and other LP gases.

Description of prior Art.
Vaporizers for liquid propane and other L.P. gases exsist. Most vaporizers use a boiler heated with direct flame on the boiler. The commercial propane contain a small amount Of butane and other heavier hydro carbons. The lighter propane boils off leaving the heavier Hydro-carbons to accumulate until the vaporizer fails.
