20120180996 | JACKETED FIRETUBE SYSTEM FOR A PROCESS VESSEL - A jacketed firetube system for use in a process vessel such as a heater or heater/treater has a jacket which extends along the firetube, at a flame inlet end. The jacket can be external to the firetube or internal to the firetube. A heat transfer fluid is circulated along the firetube between the jacket and the firetube for recovering heat from the firetube and reducing the firetube's temperature. The recovered heat is reintroduced into the system. | 07-19-2012 |
20120145373 | FIRETUBE HAVING THERMAL CONDUCTING PASSAGEWAYS - A firetube is immersed in a fluid to be heated and transfers heat from hot gases flowing through the firetube to the fluid surrounding the firetube. The firetube has a plurality of thermally conductive passageways which extend through the firetube for increasing the surface area available for heat transfer. Fluid is conducted through the passageways by a thermosiphon effect resulting from a temperature differential in the vessel, the fluid below the firetube being cooler and denser than fluid above the heat exchanger. | 06-14-2012 |
