  • Patent number: 10773880
    Abstract: A heating assembly for heating a liquid storage tank includes a heat exchanger tank supported in one wall of the storage tank to extend into the storage tank in contact with liquid stored therein. The heat exchanger tank contains a heat exchanger fluid therein which is heated by a burner tube extending through the heat exchanger tank whereby heat is only transferred to the liquid in the storage tank through the heat exchanger fluid. A controller actuates the burner head of the burner tube to maintain temperature of the heat exchanger fluid between upper and lower temperature limits. The operation of the burner head is interrupted in response to temperature of the liquid in the storage tank exceeding an upper limit, or fluid level in the heat exchanger tank being below a lower limit as determined by respective sensors.

  • Patent number: 9922740
    Abstract: A nuclear power generation system and related power cycle are disclosed, in one embodiment, the system includes primary coolant circulation through a hydraulically interconnected reactor containing nuclear fuel and a steam generating vessel collectively defining a steam supply system. Liquid secondary coolant for the power cycle flows through the steam generating vessel and is converted to steam by the primary coolant to drive a low pressure turbine of a turbine-generator set. Steam exiting the turbine is condensed and heated prior to return to the steam supply system, thereby completing a secondary coolant flow loop. In one embodiment, a majority of the secondary coolant heating occurs within the steam generating vessel via heat exchange with the primary coolant rather than externally in the secondary coolant flow loop. This creates a temperature differential between the primary and secondary coolant sufficient to create natural thermally induced convective circulation of the primary coolant.

  • Patent number: 9366476
    Abstract: A system and method for the concurrent condensation of a nitrogen-rich vapor and vaporization of an oxygen-rich liquid in a distillation column based air separation unit is provided. The disclosed system includes a condenser-reboiler heat exchanger located between a lower pressure column and a higher pressure column and configured to condense a nitrogen-rich vapor from the higher pressure column and partially vaporize an oxygen-rich liquid from the lower pressure column. Within the condenser-reboiler heat exchanger, the nitrogen-rich vapor flows in an upward direction such that any non-condensables present in the nitrogen-rich vapor will accumulate proximate the upper portion or top of the condenser-reboiler modules where they can be easily removed through venting by means of a venting apparatus having a plurality of perforated tubes.

  • Publication number: 20150007781
    Abstract: The present disclosure relates to a system for producing high pressure steam from low quality feedwater for a designated process. The system includes a first closed loop in fluid communication with a boiler and a heat exchanger assembly. A first fluid flows through the first closed loop, and is of acceptable quality for use in a boiler. Heat from the boiler is transferred to a second loop through the heat exchanger assembly. The second loop includes the low quality feedwater, which is converted to high pressure steam. The high pressure steam produced from the low quality water can be used in the designated process. This reduces corrosion/downtime in the boiler that might otherwise occur if the low quality water was directly heated by the boiler.

  • Publication number: 20140245973
    Abstract: A method of recovering oil from an oil well and producing steam for injection into an injection well is provided. After recovering an oil-water mixture from the oil well, oil is separated from the mixture to produce an oil product and produced water. In one process, the produced water is directed to an indirect fired steam generator which is powered by an independent boiler or steam generator. As water moves through the indirect fired steam generator, the same is heated to produce a steam-water mixture. The steam-water mixture is directed to the steam separator which separates the steam-water mixture into steam and water. The separated water is directed from the steam separator back to and through the indirect fired steam generator. This separated water is continued to be recycled through the indirect fired steam generator. Steam separated by the steam separator is directed into the injection well.
