20100325954 | QUENCH CHAMBER ASSEMBLY FOR A GASIFIER - A gasifier includes a combustion chamber in which a combustible 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 is disposed coupling 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 is disposed surrounding the dip tube such that an annular passage is formed between the draft tube and the dip tube. An asymmetric or symmetric 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 asymmetric or symmetric baffle so as to remove entrained liquid content from the cooled syngas before the cooled syngas is directed through the exit path. | 12-30-2010 |

In an embodiment of the quench chamber, the cooling device includes a heat exchanger pipe. A quench chamber and scrubber assembly is also disclosed. | 05-26-2011 |
20130011307 | QUENCH CHAMBER ASSEMBLY FOR A GASIFIER - 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. | 01-10-2013 |
20130011308 | QUENCH CHAMBER ASSEMBLY FOR A GASIFIER - 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 smaller towards the bottom of the quench chamber and larger towards the top of the quench chamber. | 01-10-2013 |

20120183437 | METHOD AND SYSTEM FOR TREATING PACKAGED PRODUCTS - A system and method for decontamination of product is described. An object to be treated, which may be a food product or a medical device, is placed in a substantially closed dielectric container with a working gas. The container is placed in an apparatus capable of producing a controlled electrical discharge so as to create reactive ion species within the package. The object to be treated may be exposed either the immediate products of the electrical discharge or the long lasting reactive ion species, or both, so as to treat the object to reduce or eliminate specific contaminants, which may be biological pathogens or the cause of product spoilage, or inorganic contaminants. The reactive ion species may result from an atmospheric non-equilibrium plasma (ANEP) formed by the apparatus and the treatment may be performed without significantly increasing the bulk temperature of the object being treated. | 07-19-2012 |

20100263510 | APPARATUS FOR CUTTING FOOD PRODUCT - Method and apparatus for reducing food products. The apparatus includes a casing, an impeller adapted for rotation within the casing, and a cutting device. The casing has axial and circumferential openings for product entering and exiting, respectively, the casing. The impeller includes a drum, paddles mounted to the drum, and pockets defined by and between adjacent pairs of paddles that are radially aligned with the circumferential opening of the casing as each pocket travels past the circumferential opening. The cutting device includes a knife disposed at the circumferential opening of the casing and oriented perpendicular to the axis of the impeller. The knife lies on a sector of the casing and has a cutting edge located within an interior of the casing so that the knife extends into the path of the paddles and passes through relief slots defined in the paddles as the impeller rotates. | 10-21-2010 |
