| 20110315250 | VENT HEAD - A vent head for a steam system is provided. In one embodiment, the head comprises a body defining a vent head chamber and having a vent head outlet. The vent head comprises a steam inlet conduit having a steam outlet that opens into the vent head chamber and a baffle disposed within the vent head chamber above the steam outlet. A drainage passageway is provided for fluid communication between the vent head chamber and the steam inlet conduit. In use, the steam outlet may discharge steam into the vent head chamber which impinges on the baffle, thereby separating entrained liquid water from the steam. The separated water is collected in the vent head chamber returned to the steam inlet conduit via the drainage passageway. | 12-29-2011 |
| 20110314778 | VENT HEAD - A vent head for a steam system is provided. In one embodiment, the vent head may comprise a body defining a vent head chamber and having a vent head outlet. The vent head comprises a steam inlet conduit having a steam outlet that opens into the vent head chamber and a baffle disposed within the vent head chamber and above the steam outlet. The baffle may have an impingement region and a convex portion which is disposed between the impingement region and the edge of the baffle. In use, the steam outlet discharges steam into the vent head chamber which impinges on the impingement region of the baffle, thereby separating entrained liquid water from the steam. | 12-29-2011 |
| 20110220326 | ENERGY RECOVERY UNIT - Aspects relate to an energy recovery unit comprising a vessel having a condensate inlet and a condensate outlet and a fluid feed line defining a fluid path. First and second heat exchangers are located within the vessel and are arranged to transfer heat from flash vapor and condensate respectively, to fluid in the fluid feed line. The energy recovery unit can be used to recover waste energy from condensate and flash steam and use it to pre-heat process water, such as boiler feed water. | 09-15-2011 |
| 20110213573 | FLOW METER - A flow meter for monitoring fluid flow through a pipeline, the flow meter comprising a conduit having a fluid inlet and a fluid outlet for communication with respective sections of the pipeline; a target element positioned inside the conduit between the fluid inlet and the fluid outlet, the target element being mounted for resilient axial displacement under a pressure differential between the inlet and the outlet; an arm secured at an anchor point on one side of the conduit and extending radially across the conduit, the target element being coupled to the arm for applying a load to the arm, upon said axial displacement of the target element, so as to deflect the arm relative to the anchor point; a sensor arrangement for measuring deflection of the arm at a point on the opposite side of the applied load to the anchor point; and a processor configured for providing a signal representative of the steam flow through the conduit in response to said measured deflection. | 09-01-2011 |
| 20110203684 | DEVELOPMENTS IN OR RELATING TO A CONDENSATE RECOVERY SYSTEM - A condensate recovery system may comprises a plurality of drain lines for draining condensate from an associated steam plant. Each drain line may incorporates a steam trap and feeds into a common condensate return line running between the drain lines and a condensate receiver tank. The system further may comprises an acoustic sensor positioned along the common condensate return line, upstream of the receiver tank, for providing an acoustic output indicative of the collective steam loss through steam traps upstream of the sensor. | 08-25-2011 |
| 20110137584 | METHOD OF DETECTING SLUGS OF ONE PHASE IN A MULTIPHASE FLOW - A method of detecting the presence of a slug of condensate in a conduit carrying a saturated steam comprising using a flow meter to provide an output signal representing mass flow rate of the saturated steam through the conduit; determining the rate of change of the output signal; and generating an alert in response to a predetermined profile of the output signal, when the profile includes a rate of change of the output signal falling outside a predetermined range. | 06-09-2011 |
| 20110084222 | VALVE ELEMENT FOR A CONDENSATE TRAP - There is provided a valve element for a condensate trap comprising an expansion chamber in the form of a metallic bellows having a variable axial length and having first and second ends sealed with first and second end caps respectively. A valve closure member is provided on the second end cap and is arranged to cooperate with a valve seat. A first guide member is coupled to the first end cap and axially extends into the bellows and a second guide member is coupled to the second end cap, axially extends into the bellows and cooperates with the first guide member. This allows relative axial movement between the first and second end caps but restricts relative radial movement between the first and second end caps. This helps to ensure that the valve closure member properly seats on the valve seal. | 04-14-2011 |
