  • Patent number: 10386273
    Abstract: A 3D time series vector sediment trap includes a base disposed with trap pipes which includes water flow pipes and sedimentation pipes. The water flow pipes have a horizontal water inlet at the front end, a vertical downward water outlet at the back end and the water flow pipe is internally provided with a filter screen which tilts towards the water inlet. The filter screen is internally tangential to the water flow pipe, and the sedimentation pipes are vertically fixed underneath the water flow pipes. The top end of the sedimentation pipes have an opening and bottom end thereof is closed. The opening is connected to the water flow pipe and directly faces the filter screen so that materials with a diameter greater than the screen pore diameter are intercepted by the filter screen in the water flow pipe and collected in the sedimentation pipe.

  • Patent number: 9358878
    Abstract: A fluid energy reducing device includes a body having multiple, oppositely directed flow restrictors extending away from opposite sides of the body. Each flow restrictor can have a geometric shape such as a pyramid, triangle, or a conical shape. Fluid such as a fuel traveling in a wave entering the flow restrictors accelerates as the flow area in a flow passage of the flow restrictors decreases. The work performed by accelerating the fluid flow through one or more apertures created in each flow restrictor reduces the energy of the wave, thereby reducing noise in the fluid tank having the fluid energy reducing device when the reduced size and velocity wave subsequently strikes tank structure or walls.

  • Publication number: 20140202399
    Abstract: 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.

    Abstract: A freeze resistant method for draining liquid condensate from a condensate furnace includes quickly purging the liquid condensate from a condensate reservoir. A condensing heat exchanger connected to a condensing reservoir stores liquid condensate as the system is in use. An inducer produces a positive pressure along a condensate line to the outlet of the reservoir, creating a back pressure which prevents draining of the reservoir. When the inducer is shut off, the positive pressure is removed, and the liquid condensate rapidly flushes from the reservoir. The amount of liquid condensate remaining in the system and exposed to cold conditions can be minimized.

  • Patent number: 6148844
    Abstract: A condensate removal device for removal of condensate from a fluid system. The device includes a body adapted for connection to the fluid system, the body having an inflow opening and an outflow opening. A trap between the inflow opening and the outflow opening restricts flow of fluid to permit the passage of liquid condensate but to inhibit the passage of gas. The trap includes a fixed passageway extending through the trap constructed for continuous fluid communication between the inflow opening and the outflow opening through the trap. A variable passageway extends through the trap, the variable passageway being constructed to selectively permit fluid communication between the inflow opening and outflow opening through the variable passageway in correspondence with the amount of liquid condensate in the fluid system. The device may include a labyrinth path to trap steam and pass condensate and be constructed to promote heat transfer and condensation of steam within the trap.

  • Patent number: 6131602
    Abstract: A condensate discharge device which prevents metal ions from attaching and depositing on the condensate discharge port surface. An inlet, a condensate discharge port, and an outlet are formed in a valve casing, which valve casing includes an upper casing and a lower casing. A valve seat member having a discharge passage is screwed into the lower casing. The discharge passage includes a first orifice having a smaller opening area than the condensate discharge port, and a second orifice having a smaller opening area than the first orifice. A movable member is mounted through the second orifice. On end of the movable member rests on one side of the second orifice, and another end is located on the other side of the second orifice. Condensate flows slowly through the condensate discharge port, preventing metal ions from attaching there, and flows rapidly through the second orifice.

  • Patent number: 5948128
    Abstract: A device for draining condensate from a steam system while substantially eliminating the passage of steam. The device has flanged inlet and outlet ends and includes a unitary Y-shaped body defining a fluid flow conduit, a filter device disposed within the Y-shaped body, and flanged inlet and outlet body ends configured for corresponding bolted connection with the flanged inlet and outlet ends of the steam system. The device also has an insert housing removably connected within the Y-shaped body and abutting the flanged outlet end of the steam system, and a nozzle structure removably positioned within the insert housing and having a constricted passageway in fluid communication with the fluid flow conduit. The insert housing can only be removed from the Y-shaped body by first disconnecting the Y-shaped body from the steam system, providing added safety for steam system operators.

  • Patent number: 5922094
    Abstract: An apparatus for automatically removing water from a digester system includes a sediment trap attached to a drain system wherein gas, water and sediment enter the sediment trap by way of gas lines, water and sediment are separated from the gas and settle within the sediment trap while the gas is expelled from the sediment trap, and wherein the gas pressure and weight of the water column within the sediment trap are balanced against a water column within a water outlet line to form a water seal to prevent gas from escaping into the atmosphere while simultaneously expelling excess water accumulating in the sediment trap.

  • Patent number: 5756882
    Abstract: A method is provided for accurately determining the volume of gas that has leaked through and around a cap having a mouth and a seal situated about the circumference of the mouth. The method includes the steps of positioning the cap within a testing neck on a fuel cap testing apparatus, fixing the cap in the neck to create a general sealing engagement between the seal and the neck and to cause the seal to move into the neck, and "staging" the cap for at least 2.5 seconds. Staging refers to the necessary waiting period that must pass in order to allow the seal to complete moving into the testing neck. A test is then conducted for changes in pressure within the testing neck due to low-volume gas leaks through and around the cap.

    Abstract: A corrosion protector particularly suitable for use with pressurized gas relief valve systems using conduits in which moisture may enter. The valve corrosion protector comprises a spacer located between the bolted flanges of components of the gas exhaust system, and a tubular neck attached to the spacer extends toward the conduit system exit. The neck is of a diameter less than the inner diameter of the associated conduit and flange whereby moisture upon the inner walls of the conduit system is collected between the conduit and the neck, and a bleed passage adjacent the spacer bleeds the moisture from the conduit system preventing such moisture from contacting the valve and causing corrosion.
