Abstract: A method of flow stabilizing for maintaining parallel channel flow through a multiple tube vaporizer wherein different mass flow rates may occur in the flow of the liquid to be vaporized through the different tubes. The stabilizer includes a plurality of inlet tubes in thermally isolated relationship to the vaporizer and having inner ends extending into the entrance end portions of the vaporizer heat exchanger tubes so as to discharge the incoming liquid to be vaporized inwardly of the entrance end of the exchanger tubes. A flow passage is provided for conducting vaporized liquids from the supply chamber into the heat exchanger tube entrance end portions to prevent choking of the system.

Abstract: An apparatus for providing from a supply of liquid fuel fluid a gaseous fuel fluid having a preselected calorific value. The apparatus includes means for vaporizing the liquid fuel fluid into air compressed by a compressor having a closed loop coolant system. A portion of the gaseous fuel fluid delivered from the apparatus is provided as a result of a heat exchange between a portion of the liquid fuel fluid and a coolant fluid utilized for cooling the air compressor. An adjustment means is provided for adjusting the preselected calorific value of the output gaseous fuel fluid as desired. In one form, a cascaded arrangement of means for flashing liquid fuel fluid and providing heat exchange therefrom is utilized to provide the desired gaseous fuel fluid.

Abstract: A method and apparatus for providing superheated gaseous fluid from a low temperature liquid supply wherein the liquid is provided to a closed chamber containing a heat transfer fluid to be in thermal transfer association with a vapor phase thereof. Heat is supplied to a liquid phase of the heat transfer fluid in the chamber to provide a continuous cycle of vaporization and condensation of the heat transfer fluid. A plurality of different heat sources may be provided for heating the heat transfer fluid, and one or more separate chambers may be utilized for heating the fluid.

Abstract: An apparatus for providing from a liquid fuel fluid supply an aerated gaseous fuel fluid. The liquid fuel fluid is delivered into a supply of hot air and the resultant mixture is delivered through a heat exchanger to an outlet. In the heat exchanger, a liquid fuel fluid phase of the mixture is converted to a gaseous phase thereof and condensed water is eliminated. The gaseous phase is superheated in a portion of the heat exchanger. A control is provided for limiting the level of the liquid phase in the heat exchanger.
