Blake Floyd A, Howerton Murlin T: Peak efficiency solar energy powered boiler and superheater. Martin Marietta Corporation, Sughrue Rothwell Mion Zinn & Macpeak, December 23, 1975: US3927659 (42 worldwide citation)

A cup-shaped enclosure forms an energy conversion chamber open at one end to a solar energy radiation field which is generally in axial alignment therewith, the conversion field incorporating, in order, from the thermal energy receiver aperture at the open end, a boiler heat exchanger and a superhea ...

Allan J Zadiraka: Control system for a solar steam generator. The Babcock & Wilcox Company, Vytas R Matas, Joseph M Maguire, September 15, 1981: US04289114 (40 worldwide citation)

A once-through solar steam generator assembly (16) is controlled by a control system wherein the outlet temperature of superheated steam from two independent boiler flow paths (1-12; 1'-12') is independently controlled to a common set point by a combination of water spray attemperation (32) at the p ...

Jerome S Spevack: Utilization of impure steam contaminated with hydrogen sulfide. Deuterium Corporation, Hall & Houghton, October 31, 1978: US04123506 (25 worldwide citation)

Certain impure streams, especially those from geothermal sources, are polluted with hydrogen sulfide, ammonia, carbon dioxide, other gases, and finely divided particulate solid matter in a form resembling dust or smoke. These contaminants reduce the efficiency of the steam as a heat transfer fluid, ...

Richard H Morse: Method and apparatus for controlling steam temperature at a boiler outlet. Leeds & Northrup Company, William G Miller Jr, Raymond F MacKay, December 30, 1980: US04241701 (24 worldwide citation)

Boiler outlet temperature in a sliding pressure operation is controlled in a routine way by varying the fluid or heat distribution in the boiler. The effect a change in pressure has on steam temperature is anticipated by supplying a feedforward signal to the temperature control system from drum pres ...

Nomura Masami, Nomura Masaaki, Marukuni Yuzuru: Superheated steam generator. Nomura Masami, Nomura Masaaki, October 8, 2003: EP1351016-A2 (22 worldwide citation)

A superheated steam generator of an electromagnetic induction type includes: a conduit, which provides a passageway of generated steam; a superheating tank, which is part of the conduit midway through the conduit; and a coil, which is disposed around the superheating tank and is connected to a high- ...

Ritland Paul D, Peake Charles C: Method for increasing effective scavenging vent steam within heat exchangers which condense vapor inside long tubes. Westinghouse Electric Corporation, September 18, 1973: US3759319 (22 worldwide citation)

A device for scavenging condensate from long heat exchange tubes by recirculating the steam which is passed through one portion of a U-shaped tube bundle through another portion of the tube bundle and thus reducing the build-up of slugs of liquid in the tubes by increasing the velocity therethrough ...

Donald J Dziubakowski: Advanced steam temperature control. The Babcock & Wilcox Company, Vytas R Matas, Robert J Edwards, October 11, 1988: US04776301 (21 worldwide citation)

A control system for a heat exchanger, such as a superheater in a fossil fuel fired steam generator, uses a multivariable non-linear regression equation to develop a feed forward signal that continuously adapts itself to changes in system variables to adjust the enthalpy of the steam entering the su ...

Robert W Fisk: Shell and tube moisture separator reheater with outlet orificing. General Electric Company, John F Ahern, November 17, 1981: US04300481 (20 worldwide citation)

Shell and tube heat exchangers achieve greater efficiency and substantially eliminate instabilities due to condensate subcooling by the location of flow restricting orifices at the outlet ends of heat exchanger tubes adjacent to the outlet header. Outlet orificing preferentially passes liquid conden ...

Self Richard E: Method of and device for conditioning steam. May 15, 1973: US3732851 (20 worldwide citation)

Steam is conditioned, to reduce its temperature and pressure, by introducing cooling water into the steam and thereafter reducing the steam pressure.
