摘要： The heat exchange system is for heating water from a water source and comprises first and second flooded heat exchangers that have steam sides that are each independently fed with steam, but water sides that are serially fed with water through the first heat exchanger then through the second heat exchanger. The system also comprises first and second control valves located at or downstream of subcooled condensate outlets of the first and second heat exchangers, first and second water temperature sensors at or downstream of the heated water outlets of the first and second heat exchangers, and a control device for receiving temperature data from the first and second water temperature sensors and for controlling the first and second control valves. The proportions of the first and second steam sides that are flooded are respectively selectively adjusted by controlling the debit of condensate allowed through the first and second subcooled condensate outlets with the first and second control valves, for allowing heat exchange to the water to be adjusted as a result of the water temperature measured by the first and second water temperature sensors. The first and second control valves are set in one of a first state in which they are both at least partly opened to allow effective heat exchange from the steam to the water in both first and second heat exchangers, and a second state in which one of them is closed while the other is at least partly opened to have an effective heat exchange from the steam to the water in only one of the first or second heat exchangers while the first and second steam sides remain both supplied with steam.

摘要： An apparatus for the production of air gases by the cryogenic separation of air can include a cold box having a heat exchanger, and a system of columns; a pressure monitoring device; and a controller. The cold box can be configured to receive a purified and compressed air stream under conditions effective for cryogenically separating the air stream to form an air gas product. The apparatus may also include means for transferring the air gas product from the cold box to an air gas pipeline. The pressure monitoring device is configured to monitor the pipeline pressure, and the controller is configured to determine whether to operate in a power savings mode or a variable liquid production mode. By operating the apparatus in a dynamic fashion, a power savings and/or additional high value cryogenic liquids can be realized in instances in which the pipeline pressure deviates from its highest value.

摘要： An object of the present invention is to allow uniform distribution of a refrigerant by a distributor. A refrigerant pipe includes a bent pipe formed in the shape of a curve and a downstream pipe connected to the downstream side of the bent pipe and formed to be linear. A distributor to distribute the refrigerant into a plurality of flow paths is connected to the downstream pipe on the downstream side. An inner wall on the inner peripheral side of the bent pipe being on the side of the curvature center of the curve is a grooved surface with a groove formed therein, and an inner wall on the outer peripheral side of the bent pipe being on the side opposite to the curvature center of the curve is a smooth surface.

摘要： A method for converting heat to electric energy is described which involves thermally cycling an electrically polarizable material sandwiched between electrodes. The material is heated by extracting thermal energy from a gas to condense the gas into a liquid and transferring the thermal energy to the electrically polarizable material. An apparatus is also described which includes an electrically polarizable material sandwiched between electrodes and a heat exchanger for heating the material in thermal communication with a heat source, wherein the heat source is a condenser. An apparatus is also described which comprises a chamber, one or more conduits inside the chamber for conveying a cooling fluid and an electrically polarizable material sandwiched between electrodes on an outer surface of the conduit. A gas introduced into the chamber condenses on the conduits and thermal energy is thereby transferred from the gas to the electrically polarizable material.

摘要： Steam power plants utilize high pressure and low pressure feedwater heaters to increase overall system efficiency. Both types of feedwater heaters generally include a subcooling zone that is separate from a condensing zone. The viability of the separation of the zones is critical to the efficiency of the overall system, specifically with regard to the inefficiencies inherent in the leakage of steam from the condensing zone into the subcooling zone. An improvement in the viability of that zone separation for such feedwater heaters is taught by the use of dual end plates for the subcooling zone to create a triple layer of separation between the condensing and subcooling zones to prevent unwanted and inefficient steam leakage.
