Turbogenerator exhaust silencer

Abstract

An exhaust silencing device and method for silencing a turbogenerator includes a housing, an intake manifold, at least two exhaust outlet ports and flow channels which extend in a bifurcated path from the intake manifold to the exhaust outlet ports and which provide a length to height (or diameter) ratio permitting a compact fluid flow profile.

What is claimed as new and desired to be secured by Letters Patent of the United States is:  
     
         1 . An exhaust silencer device, comprising: 
 a housing;    an intake wall and an exhaust wall disposed within said housing, said intake wall and said exhaust wall and forming a flow channel;    an intake manifold formed within said intake wall;    at least two exhaust outlet ports formed within said exhaust wall; and    wherein said flow channel extends from said intake manifold, said flow channel is bifurcated to terminate at said two exhaust outlet ports.    
     
     
         2 . The exhaust silencer device of  claim 1 , wherein said flow channel is formed as a substantially T-shaped configuration.  
     
     
         3 . The exhaust silencer device of  claim 1 , wherein said flow channel has a length to height ratio that results in a compact fluid flow profile.  
     
     
         4 . The exhaust silencer device of  claim 1 , wherein sound attenuating material is disposed within said housing.  
     
     
         5 . The exhaust silencer device of  claim 4 , wherein said sound attenuating material is selected from the group consisting of fiberglass, mineral wool and ceramic wool.  
     
     
         6 . The exhaust silencer of  claim 4 , wherein said sound attenuating material is a fiberous bulk material.  
     
     
         7 . The exhaust silencer device of  claim 4 , wherein the sound attenuating material is in a form selected from the group consisting of woven material, blankets and blown material.  
     
     
         8 . The exhaust silencer of  claim 1 , wherein said flow channel has a length to height ratio between about 1 to about 20.  
     
     
         9 . The exhaust silencer of  claim 1 , wherein said bifurcation delivers a shape angle of at least 140°.  
     
     
         10 . An exhaust silencer system, comprising: 
 an exhaust silencer device including a housing, an intake manifold, at least two exhaust outlet ports and a flow channel formed in said housing, said flow channel extend from said intake manifold to the exhaust outlet ports in a bifurcated configuration; and    a turbogenerator coupled to said intake manifold, said turbogenerator supplying exhaust to said exhaust silencer device.    
     
     
         11 . The exhaust silencer system of  claim 10 , wherein said bifurcated configuration is substantially T-shaped.  
     
     
         12 . The exhaust silencer system of  claim 10 , wherein the diameter of said flow channel are based on the length such that a compact fluid flow profile is formed.  
     
     
         13 . The exhaust silencer system of  claim 10 , wherein said flow channel has a length to height ratio from about 1 to about 20.  
     
     
         14 . The exhaust silencer system of  claim 10 , wherein sound attenuating material is disposed within said housing.  
     
     
         15 . The exhaust silencer system of  claim 14 , wherein said sound attenuating material is selected from the group consisting of fiberglass, mineral wool and ceramic wool.  
     
     
         16 . The exhaust silencer system of  claim 14 , wherein the sound attenuating material is in a form selected form the group consisting of woven material, blankets and blown material.  
     
     
         17 . A method for silencing exhaust flow associated with a turbo generator, comprising: 
 directing exhaust flow into an intake manifold; and    directing said exhaust flow from said intake manifold to at least two exhaust outlet ports via a flow channel;    wherein said exhaust flow is bifurcated between said intake manifold and said at least two exhaust outlet ports such that said exhaust flow includes a compact fluid flow profile.    
     
     
         18 . The method of  claim 15 , wherein the bifurcated flow forms a shape angle of at least 140°.  
     
     
         19 . The method of  claim 15 , wherein said flow channel has a length to height ratio of between about 1 and about 20.  
     
     
         20 . The method of  claim 15 , wherein said flow channel has a length to diameter ratio of between about 1 and about 20.
