Non-condensing exhaust system

Abstract

An exhaust system for relatively cooled gases. The exhaust system includes an exhaust pipe and a heater. The exhaust pipe is adapted to contain a flow of cold exhaust gas and the heater is adapted to heat the flow of cold exhaust gas.

1 . An exhaust system comprising: 
 an exhaust pipe coupled to pass a flow of cold exhaust gas; and    a heater adapted to heat the flow of cold exhaust gas.    
   
   
       2 . The exhaust system of  claim 1 , further comprising: 
 the exhaust pipe having a first end adapted to receive the cold exhaust gas.    
   
   
       3 . The exhaust system of  claim 1 , further comprising: 
 the exhaust pipe having a second end adapted to expel the cold exhaust gas.    
   
   
       4 . The exhaust system of  claim 1 , wherein the exhaust pipe is made from a thermally conductive material.  
   
   
       5 . The exhaust system of  claim 1 , wherein the exhaust pipe is made from one of stainless steel and copper.  
   
   
       6 . The exhaust system of  claim 1 , wherein the heater is a wire heater that is wrapped around the exhaust pipe.  
   
   
       7 . The exhaust system of  claim 1 , wherein the exhaust pipe is coupled to pass a flow of GN 2  exhaust.  
   
   
       8 . The exhaust system of  claim 1 , wherein the exhaust pipe has a bend.  
   
   
       9 . A method of preventing condensation on an exhaust pipe having cooled exhaust flowing there through, the method comprising: 
 directing a flow of cold exhaust into the exhaust pipe; and    heating the exhaust pipe with a heater embedded with the exhaust pipe.    
   
   
       10 . (canceled)  
   
   
       11 . The method of  claim 9 , further comprising: 
 outputting the flow of exhaust.    
   
   
       12 . The method of  claim 9 , further comprising: 
 transferring thermal energy from the pipe to the flow of cold exhaust.    
   
   
       13 . The method of  claim 9 , wherein the flow of cold exhaust is GN 2  exhaust.  
   
   
       14 . A method of forming an exhaust system, the method comprising: 
 integrating a heater with an exhaust pipe that is coupled to receive a cold exhaust flow.    
   
   
       15 . The method of  claim 14 , further comprising: 
 adapting a first end of the exhaust pipe to receive the flow of cold exhaust.    
   
   
       16 . The method of  claim 14 , further comprising: 
 adapting a second end of the exhaust pipe to expel the flow of cold exhaust.    
   
   
       17 . The method of  claim 14 , wherein integrating the heater with the exhaust pipe further comprises: 
 wrapping the heater around the exhaust pipe.    
   
   
       18 . The method of  claim 14 , further comprising: 
 forming a bend in the exhaust pipe.
