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.
