摘要： Embodiments of the present disclosure can include a system for generating steam. The system can include a direct steam generator configured to generate saturated steam and combustion exhaust constituents. A close coupled heat exchanger can be fluidly coupled to the direct steam generator, the close coupled heat exchanger can be configured to route the saturated or superheated steam and combustion exhaust constituents through an exhaust constituent removal system. The system can include an energy recovery system that reclaims the energy from the exhaust constituents.

摘要： Steam generators in power plants exchange energy from a primary medium to a secondary medium for energy extraction. Steam generators include one or more primary conduits and one or more secondary conduits. The conduits do not intermix the mediums and may thus discriminate among different fluid sources and destinations. One conduit may boil feedwater while another reheats steam for use in lower and higher-pressure turbines, respectively. Valves and other selectors divert steam and/or water into the steam generator or to other turbines or the environment for load balancing and other operational characteristics. Conduits circulate around an interior perimeter of the steam generator immersed in the primary medium and may have different cross-sections, radii, and internal structures depending on contained. A water conduit may have less flow area and a tighter coil radius. A steam conduit may include a swirler and rivulet stopper to intermix water in any steam flow.

摘要： An Air Separation Unit is disclosed which is thermally integrated into a coal fired oxy boiler power plant. The Air Separation Unit has a Dryer with a dryer heater, wherein an extraction line connects the steam extraction port to the dryer heater. A drain line of the dryer heater then fluidly connects the regeneration heater to a point of a Rankine steam cycle fluidly within the condensate system.

摘要： Apparatus for electric power generation. A system includes a boiler for heating a fluid, the boiler directing a first portion of the heated fluid to a turbine for the generation of electric power and a second portion of the heated fluid to a thermoelectric (TE) generator, and a condenser connected to the turbine that condenses hot fluid emitted from the turbine and feeds the condensed fluid to the TE generator, the TE generator generating electric power from a difference in temperature of the second portion of the heated fluid and the condensed fluid from the turbine.

摘要： In a multi-stage steam power plant a portion of the bleed steam is passed through a heat exchanger in the combustion air input duct to preheat the combustion air. The condenser output water is also passed through a heat exchanger in the combustion air input duct and then, before returning to the boiler feed water line, is passed through a heat exchanger in the flue and then a further heat exchanger in the air input duct. In this way heat from the condensate is retained in the system and heat from the flue gas is returned to the intake combustion air.

摘要： An apparatus for rapidly evaporating liquid includes an exhaust flow channel having opposing openings including an upstream opening and a downstream opening. The channel defines an exhaust path proceeding from the upstream opening through the exhaust flow channel and through the downstream opening. Within the exhaust flow channel, a conduit path includes repeated passes transverse to the exhaust path. Attached to the exhaust flow channel proximate the downstream opening, a spray fixture is coupled to an exit port of the conduit. The spray fixture includes a divider to divide fluid from the exit port into multiple streams and an aimer to direct the multiple streams into the exhaust path.
