  • Patent number: 9163829
    Abstract: A moving bed heat exchanger (155) includes a vessel having an upper portion (200), a lower portion (210) with a floor (272) including a discharge opening therein, and an intermediate portion (205). The vessel directs a gravity flow of hot ash particles (140) received thereby from the upper portion (200) through the intermediate portion (205) to the floor (272) of the lower portion (210) of the vessel, where the hot ash particles (140) are collected. Tubes in the intermediate portion (205) of the vessel direct a flow of working fluid in a direction substantially orthogonal to the direction of the gravity flow of the hot ash particles (140) through the intermediate portion (205) of the vessel such that heat from the hot ash particles (140) is transferred to the working fluid thereby cooling the hot ash particles (140).

  • Patent number: 8307821
    Abstract: 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.

  • Publication number: 20090260622
    Abstract: 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.

  • Patent number: 5320652
    Abstract: 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 optional 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. The conical extraction skimmers include an outwardly protruding rim portion which forms an enlarged annular chamber between the rim and the underlying conical extraction skimmer. This forms a converging-diverging flow path out between skimmer sections and an outwardly extending ring forms a tortuous path.

  • Patent number: 5279158
    Abstract: A liquid level measuring system for the steam drum of a steam generator employs a plurality of bubblers spaced along the length of the drum to obtain a level profile. The steam pressure to the bubblers is supplied by tubes connected to the steam/water inlet space which has a pressure significantly higher than the steam space in the drum. Horizontal pressure taps on each bubbler transmit the pressure to pressure cells external to the drum where the bubbler pressure is compared to the pressure in the steam space. These reading can then be converted to liquid level readings.

  • Patent number: 5271753
    Abstract: A liquid-vapor separating drum has a screen dryer mounted in the upper portion between the primary separators and the vapor outlet. The screen dryer is constructed and mounted in such a way that only minimal access is required in the space above the screen dryer whereby the space can be minimized. A central pair of dryer rows is installed first when there is easy access. The two outside rows are then merely clipped in place which does not require any access. The bottoms of the rows are joined by drain panels which form a flow barrier and which serve to collect the liquid extracted by the screens. Hanging rods are used to support these drain panels and thereby indirectly support the bottoms of the rows. Vortex breakers in drain apertures of the drain panels improve the drainage rate.
