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 ...

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 ...
