Patent number: 8758458Abstract: A gasifier includes a combustion chamber in which a fuel is burned to produce a syngas and a particulated solid residue. A quench chamber is disposed downstream of the combustion chamber. A dip tube is disposed coupling the combustion chamber to the quench chamber. The syngas is directed to contact liquid coolant in the quench chamber and produce a cooled syngas. A draft tube is disposed surrounding the dip tube such that an annular passage is formed. A baffle is disposed proximate to an exit path of the quench chamber. The cooled syngas is directed through the annular passage and impacted against the baffle so as to remove entrained liquid content from the cooled syngas before it is directed through the exit path. A cross sectional area of the annular passage is larger towards the bottom of the quench chamber and smaller towards the top of the quench chamber.Type: GrantFiled: September 14, 2012Date of Patent: June 24, 2014Assignee: General Electric CompanyInventors: Prashant Tiwari, Gregory Michael Laskowski, Judeth Brannon Corry, Helge Burghard Herwig Klockow, Allyson Joy Jimenez-Huyke, Shailesh Singh Bhaisora, Steven Craig Russell, Karl Hardcastle, Jennifer Lynn Moyer, Scott Reginald Parent, Yulianto Salahuddin Mohsin

Patent number: 8673036Abstract: A gasifier includes a combustion chamber in which a fuel is burned to produce a syngas and a particulated solid residue. A quench chamber having a liquid coolant is disposed downstream of the combustion chamber. A dip tube couples the combustion chamber to the quench chamber. The syngas is directed from the combustion chamber to the quench chamber via the dip tube to contact the liquid coolant and produce a cooled syngas. A draft tube surrounds the dip tube such that an annular passage is formed between the draft tube and the dip tube. An asymmetric or symmetric faceted baffle is disposed proximate to an exit path of the quench chamber. The cooled syngas is directed through the annular passage and impacted against the baffle so as to remove entrained liquid content from the cooled syngas before the cooled syngas is directed through the exit path.Type: GrantFiled: September 14, 2012Date of Patent: March 18, 2014Assignee: General Electric CompanyInventors: Prashant Tiwari, Gregory Michael Laskowski, Judeth Brannon Corry, Helge Burghard Herwig Klockow, Allyson Joy Jimenez-Huyke, Shailesh Singh Bhaisora, Steven Craig Russell, Karl Hardcastle, Jennifer Lynn Moyer, Scott Reginald Parent, Yulianto Salahuddin Mohsin

Patent number: 8240993Abstract: An air distribution system for manipulating a boundary layer of air across a wind turbine rotor blade. The wind turbine rotor blade includes at least one sidewall that defines a cavity therein. The sidewall extends between a leading edge and an axially-spaced trailing edge, and defines a chordwise axis between the leading edge and the trailing edge. The air distribution system includes a plurality of bleed flow assemblies that are positioned within the rotor blade and are configured to discharge air into the boundary layer to reduce a separation of the boundary layer from the rotor blade. Each bleed flow assembly of the plurality of bleed flow assemblies includes a bleed flow conduit that is coupled to an inner surface of the sidewall and is oriented with respect to the chordwise axis between the leading edge and the trailing edge. The bleed flow conduit is configured to channel air through the rotor blade.Type: GrantFiled: January 4, 2011Date of Patent: August 14, 2012Assignee: General Electric CompanyInventors: Shailesh Singh Bhaisora, Narasimha Shastri, Anurag Gupta
