20090010721 | STEAM/WATER CONICAL CYCLONE SEPARATOR - A conical cyclone separator for separating steam from water in a steam/water mixture supplied to a steam drum of a boiler, comprises a conical portion with upper and lower cylindrical portions. Using a widened tangential inlet that extends the axial length of the conical portion of the separator, the disclosed separator has an inlet which is increased in width by approximately 16% with no derogation in steaming capacity but with substantially less pressure drop. The inlet design of this separator does not increase the overall length of the separator allowing for its use in smaller diameter steam drums that would be unable to currently utilize conventional separators. | 01-08-2009 |
20100101564 | SHOP-ASSEMBLED SOLAR RECEIVER HEAT EXCHANGER - A shop-assembled solar receiver heat exchanger having an arrangement of heat transfer surfaces and a vertical steam/water separator structurally and fluidically interconnected thereto. A vertical support structure is provided to support the vertical separator and the heat transfer surfaces. The vertical support structure is bottom supported, while the vertical steam/water separator and heat exchanger heat transfer surfaces are top supported from the vertical support structure. The vertical support structure provides structural support and rigidity for the heat exchanger and a means by which the heat exchanger can be picked up and lifted for placement at a desired location. A fabrication/transport/lifting fixture is provided which facilitates fabrication, assembly, transportation and erection of the heat exchanger from the shop to the field. The fixture supports two trunnion shafts attached to the support structure of the receiver. Lifting lugs would be located on the top end of the support structure. Upon arrival at the job site in the field, a crane lifts the heat exchanger receiver to vertical, rotating about the trunnion shafts on the fixture, and then lifts the heat exchanger receiver for placement at a desired location. | 04-29-2010 |
20100229805 | INTEGRATED SPLIT STREAM WATER COIL AIR HEATER AND ECONOMIZER (IWE) - An integrated water coil air heater and economizer arrangement for a boiler has a feedwater inlet for supplying feedwater to the boiler, and conduits and a valve for splitting the feedwater from the inlet into a first partial lower temperature, lower mass flow stream, and a second partial higher temperature, higher flow stream. A water coil air heater for passage of air to be heated for the boiler contains at least one heat transfer loop in heat transfer relationship with the air, the heat transfer loop of the water coil air heater being connected to receive the first partial stream. An economizer for passage of flue gas to be cooled for the boiler contains at least one heat transfer loop in heat transfer relationship with the flue gas, the heat transfer loop of the economizer being connected to the heat transfer loop of the water coil air heater for receiving the first partial stream from the water coil air heater. A mixing location downstream of the economizer receives and reunites the first and second partial streams and a conduit carries the second partial stream from the feedwater inlet to the to the mixing location. | 09-16-2010 |
20110188338 | STEPPED DOWN GAS MIXING DEVICE - An apparatus and method for mixing gas streams of different temperatures and/or compositions contemplates that at least one of the streams contains particle. The apparatus includes a main duct for the first gas stream and a plurality of duct assemblies extending in the main duct generally transversely to the first gas stream. Each assembly has plural inlets and outlets for receiving and discharging separate parts of the second gas stream, moving initially generally transverse to the first stream. The assemblies each have plural secondary ducts of mutually different lengths from inlet to outlet, the outlets being spaced from each other across the main duct for distributing the parts of the second gas stream into the first gas stream. A gas flow deflector is connected to each duct assembly for temporarily deflecting the first gas stream before it is combined with the parts of the second gas stream. | 08-04-2011 |
20130118477 | FREEZE PROTECTION SYSTEM FOR SOLAR RECEIVER - A solar receiver has an arrangement of heat transfer surfaces and a heat transfer fluid phase separator, such as a vertical steam/water separator, fluidly interconnected thereto. The receiver includes a plurality of heat transfer fluid filled components, and at least one alternate heat source. When various temperature measurements indicate freezing or solidification of the fluid is possible, the alternate heat source is activated to maintain a temperature of the fluid greater than the freezing/solidification point of the fluid. The application of the alternate heat source further induces natural circulation of the fluid within the components, further providing freeze/solidification protection to the receiver. A controller may be configured to receive sensed temperatures of the fluid, components, ambient air, etc., and use these temperatures relative to a threshold temperature to activate, vary output, and deactivate one or more alternate heat sources. | 05-16-2013 |
20130118481 | SOLAR RECEIVER WITH DUAL-EXPOSER HEAT ABSORPTION PANEL - A dual-exposure heat absorption panel is disclosed, which can be used in a solar receiver design. Generally, the heat absorption panel includes a tube panel through which a heat transfer fluid is flowed to absorb solar energy from heliostats that are focused on the tube panel. A structural support frame surrounds the tube panel. A stiffener structure runs across the exposed faces of the tube panel. The headers and other support structures on the periphery are protected by use of a heat shield. | 05-16-2013 |
20130118482 | HIGH EFFICIENCY SOLAR RECEIVER - A solar receiver includes a multi-sided central assembly with wing assemblies extending from corners thereof. The central assembly includes one-sided heat absorption panels, while the wing assemblies use two-sided heat absorption panels. Stiffener structures run across the exposed faces of the various heat absorption panels. | 05-16-2013 |
20140041359 | RAPID STARTUP HEAT RECOVERY STEAM GENERATOR - A rapid startup heat recovery steam generator (HRSG) comprises a gas inlet, a high pressure section, an optional intermediate pressure section, an optional low pressure section, and a gas outlet. At least one of the pressure sections includes a vertical steam separator. | 02-13-2014 |
