摘要:
A continuous moving bed solar steam generation and storage system is provided to generate steam for production processes after loss or reduction of received solar energy. The system includes a receiver 10 that receives a flowing stream of particulate material 30 that absorbs solar radiant energy 15 as it passes through beams of the energy 15 received from collectors 14. The heated stream of material 30 passes into a first chamber 40 to heat a tube bundle 42 therein. Heat from the particulate material 30 is transferred to the bundle 42, evaporating the water to generate, reheat (RH) and/or superheat (SH) steam 46. The cooled material 30 passes to a second chamber 60. The material 30 is drained from the second chamber 60 and carried to a cyclone 80 in the receiver 10. The material 30 drains from the cyclone 80 to complete the flow cycle.

A solar power generation system includes a solar receiver disposed on a tower that receives radiant heat reflected from a field of solar collectors. The solar receiver includes an evaporator having a plurality of vertically oriented tubes to form a panel for receiving a fluid, such as water and/or steam, wherein the tubes have a rifled internal surface. The fluid within the tubes has a mass flow greater than 0.2×106 lb/hr/ft3 at a pressure in the range of 100-2850 psia, wherein radiant heat fluxes on the outside of the tubes exceed 185,00 but/hr/ft2.

A standby heat supply system is provided for a solar receiver steam generator to maintain the system at a relatively constant temperature during the nocturnal period when solar radiation is unavailable. An exemplary solar steam generator having a standby heat supply system includes a steam loop having at least one solar panel, a steam drum and circulating pump, whereby solar energy heats the water to generate steam which is provided to the steam drum. The standby heat supply system includes an external standby heater wherein the water from the steam drum is provided to the external standby heater. A heat isolation valve is actuated during the nocturnal period to allow the water to circulate through the standby heater. Another exemplary embodiment of a solar steam generator includes an internal standby heat supply system having heater elements immersed in the steam drum for direct heating of the water during nocturnal periods.

A sealpot for a combustion power plant includes a downcomer standpipe which receives solids of the combustion power plant, a bed including a first end and a second opposite end, the first end connected to the downcomer standpipe, a discharge standpipe disposed at the second opposite end of the bed, and an orifice plate disposed between the bed and the discharge standpipe separating the discharge standpipe from the bed. The orifice plate includes apertures disposed at a height above the bed which allow transport of fluidized solids and gas through the orifice plate.

摘要:
A liquid-vapor separator for two-phase fluids in general and specifically a steam-water separator in a steam drum of a steam generator includes axial or radial spinner blades to create a centrifugal motion which causes liquid to be forced outward against the outer wall and the vapor to be concentrated in the center. Conical extraction skimmers systematically extract and discharge the liquid outwardly and downwardly through the side walls such that it impinges on an oval discharge screen surrounding the skimmers. The vapor flows out the top through a central opening and enters a secondary separator packed with crimped wire mesh encased in a perforated enclosure.
