  • Patent number: 11828461
    Abstract: A dew point corrosion resistant heat exchanging system having a plurality of hollow heat transferring tubes through which cooler ambient air or hot combustion product gases flow. The other of the air or gas flows across the outer surfaces of the tubes, and heat is transferred from the hot gases to the ambient air, thus heating the air. A portion of the tubes includes an inner liner forming an air pocket chamber between the liner and the outer wall of the tube. The air pocket chamber provides heat transfer advantages that maintain the tubes at a temperature above the dew point of the gases in the system, thus inhibiting corrosion of the tubes.

  • Patent number: 8981628
    Abstract: The present invention provides an ultra violet irradiating device for aligning liquid crystal and also an water-cooling coaxial tube. The ultraviolet irradiating device includes a water-cooling coaxial tube configured with an inter tube and an external pipe enveloping the internal pipe. A light tube is disposed within the internal pipe, and an infrared filter layer is disposed between the internal and external pipes; and an ultra violet filter layer is coated over an external surface of the external pipe so as to filter out an ultra violet light beam having wavelength lower than 320 nm. The breakage of the unit filters resulted from inter pushing with each other or leakage resulted from overlapping of the unit filters can be readily resolved.

  • Patent number: 8978745
    Abstract: An exhaust gas heat recovery (EGHR) heat exchanger, for recovering waste heat from the hot exhaust gases of an internal combustion engine, having a housing and a cylindrical body disposed within the housing. The cylindrical body defines a central passageway and together with the housing defines an annular passageway for the flow of hot exhaust gases. A bypass means is disposed within the central passageway and adapted to selectively by-pass at least a portion of the exhaust gas from the central passageway to the annular passageway. The EGHR heat exchanger also includes at least one fluid tube extending along a tube axis and having at least one lobe extending the length of the tube thereby defining a lobed tube. The lobed tube is twisted about the tube axis forming a twisted lobed tube which is then coiled about the longitudinal axis within the annular exhaust gas passageway.

  • Patent number: 8980193
    Abstract: Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.
