Graphite tube condensing heat exchanger and method of operating same

摘要: The present invention is directed to a method for recovering heat from gas stream contaminated with water vapor and an acid-forming moiety, said having acid dew point ranging about 200° F. 300° 90.20 150° inventive comprises passing the through exchange fitted plurality of generally-parallel tubes which flow exchanging fluid counter-current in exchanger. at temperature such that exterior tube or below both points, exiting exchanger points. are formed acid-resistant, resin-impregnated graphite exhibit smooth, washable surface. further pair side apertured sheets penetrate. ends penetrating interconnected non-graphite connectors establishing path therethrough. house interior heat-exchange chamber therebetween flows.
