摘要: An improved heat exchanger that reduces the thermal stress in components thereof especially tube plates or tube sheets so as to enable greater temperature differences across adjacent components while reducing the temperature gradient and thus extending the life of the heat exchanger is accomplished by attaching or bonding an insulating material of low thermal conductivity such as a sheet of PTFE, a metal jacketed layer of insulating cork or nonmetallic composite such as micarta sheeting to the metal component or tube sheet or tube plate.

摘要: The present invention relates to an improved heat transfer device and process, such as the heat exchanger included in a process for vaporizing cryogenic fluids industrial gas supply systems. The system having a water bath and heat exchange tube bundle disposed therein operating to vaporize and superheat industrial liquefied gases including fuel gases. Water contained in a tank transfers heat to the bundle by natural convection without benefit of forced water circulation. The water is heated by means such as steam, combustion processes or electric heat and a heat exchange tube bundle submerged within the water tank is used to vaporize and superheat liquefied gas, which passes within the tubular elements of the heat exchange bundle. Gas bubble agitation is provided by discharging nitrogen, air or other non-condensing gas into the water via a gas-sparging manifold located below the tube bundle for the purpose of increasing the rate of heat exchange from the heated water to the cooler liquefied gas and increasing the useable energy storage capacity of the water during operation when the heating means is shut off.

摘要: A cryogenic fluid vaporizer using ambient air comprising a conduit through which the fluid is passed having an outer finned tubular sleeve which includes a thermal insulation barrier between the conduit and the outer finned tubular sleeve. A fan may be included to provide an increased rate of heat transfer from the air to the outer surface of the fins of the tubular sleeve. The combination of the externally finned area and the insulating thermal barrier prevents the information of ice or frost on the exterior surface of the fins during the transfer of heat from the ambient air to the cryogenic fluid providing a frost-free cryogenic ambient air vaporizer for continuous operation.

摘要: A method for eliminating ground fog which results from vaporizing cryogenic fluids using ambient air. The method includes the steps of drawing an ambient air stream through an ambient air vaporizer thereby cooling the air stream and vaporizing the cryogenic fluid, and then passing the cooled air stream through a vent stack. The method further includes isolating the inlet air stream from the cold outlet air stream and dispersing the cold air into the atmosphere upon leaving the stack. The method further controls the relationship of the stack exit location and the ambient air vaporizer to prevent a temperature depression in the air surrounding the vaporizer which depression causes reduced vaporizer performance.
