Second, the Zhi Chengguan 400 being shown in which provide bearing assembly for reinforcement structure 401,402.Real at other Executing in example, reinforcement structure can use independent supporting control to obtain.Such as, Zhi Chengguan can cross first Hold height 225 to extend, but not crossing to extend in the second support height 226 returns；If necessary, different Zhi Chengguan may be used for the reinforcement structure at the second support height 226.3rd, as indicated, reinforcement structure 401 use two independent Zhi Chengguan 400,406.It is contemplated that only one of which supporting pipe is for reinforcement structure Other embodiments.This can be such as by being formed around the rectangle anchor ring (torus) of tube panel by supporting pipe And realize.This single Zhi Chengguan can provide the reinforcement structure 401 adjacent with the first surface shielded, and then wraps up It is in the screen on identical height, and the reinforcement structure adjacent with another surface of screen is provided.Knot is strengthened second Can also be realized by the Zhi Chengguan of identical Zhi Chengguan or different at structure height 402.

It should also be noted that in figure 3, each be in the charge of be connected on the same side tube panel upper header and Lower collector pipe.Such as Zhi Chengguan 400 is simultaneously connected to upper header 242 and lower collector pipe along first side edge 216 250.It should be appreciated that this can be different.Such as, if an only reinforcement structure, then Zhi Chengguan 400 can be connected to upper header 242 along the first edge 216, then across first surface and along Dual side-edge edge 218 is connected to lower collector pipe.

As it has been described above, the solar receiver of the present invention includes alar part assembly and middle part receiver assembly.Now Some different middle part receiver assemblies are described.

Fig. 9 is the view sub-anatomy of each parts of an exemplary embodiment of middle part receiver assembly.At this In exemplary embodiment, it is considered to heat-transfer fluid (HTF) is steam and water.Usually, middle part receptor group Part 800 has internal supporting structure 810 and tube panel 820 in the middle part of at least one.

Internal supporting structure 810 described herein from the side time be rectangle, time be seen from above square (i.e. overlooking surface figure).Here, internal supporting structure 810 by four vertical pylons 812 and is arranged horizontally in each Between pylon, the reinforcement 814 on three height is assembled into.Vertically pylon is attached to substrate 816.Internal Bearing structure 810 limits internal between holding 811, the positioning parts of solar receiver hold inside this between in 811 And it is not exposed to concentrate sunlight.Such as, here, vertical steam/water separator 802 is positioned at internal between holding In 811.Between internal appearance, 811 by outside tube panel and stop sunlight through the most bound tangent pipe Screen is protected against the irradiation concentrating sunlight.The terrace at entrance being in two level heights being shown in which 818 in order to the path in providing between the inside appearance entering this internal supporting structure.

Solar receiver described here has as vaporizer tube panel 822 and the two of superheater tube screen 824 Tube panel 820 in the middle part of set difference.Each middle part tube panel 820 extends between upper header 826 and lower collector pipe 828. Vertically steam/water separator 802 structurally interconnects with tube panel 822 and 824 with on fluid.Internal Bearing structure 810 support upright steam/water separator 802 and middle part tube panel 820.At reinforcement 814, in Portion's tube panel 820 is installed to internal supporting structure 810.

As indicated, each side of receptor 800 includes a vaporizer tube panel 822 and a superheater tube screen 824.A corner of receiver assembly 800 in the middle part of two main superheater (PSH) tube panels 824 formation, And two superheater (SSH) tube panels 824 form another corner (not shown).In view of the flexibility of pipe, Vaporizer tube panel 822 and superheater screen 824 are generally by the most bound pipe of the tangent of tight spacing (without film) Constitute, there is near collector the abundant pipe bend providing extra flexibility.Pipe can be minor diameter thin wall pipe With minimum heat-transformation side to cold side and the temperature difference of whole tube wall and thermal stress.Tube panel can the most in the horizontal direction With carry out thermal expansion on vertical direction, thus minimize pipe stress.It is also contemplated that vaporizer tube panel 822 He Other arrangement of superheater tube screen 824.Such as, vaporizer tube panel 822 and superheater tube screen 824 can Not to be positioned on every side, or superheater tube screen 824 can not intersect in corner portion, or the most permissible Given side arranges heteroid multiple vaporizer tube panel 822 and superheater tube screen 824.

Upper header 826, lower collector pipe 828 and other parts are extended by the periphery around middle part receiver assembly 800 Heat cover protect against overflow and dissipate from luminous energy.Upper heat cover 840 is in the top of middle part tube panel 820, lower heat Cover 842 is in the lower section of middle part tube panel 820.The exposed side of heat cover can be with painted white to reduce operating temperature. The dorsal part of heat cover is frequently not heat insulation, to reduce operating temperature.Heat cover 840,842 and middle part tube panel 820 Between can also there is space, to be allowed for the gravity-flow ventilation additionally cooled down.

Explain that fluid flowing can help to the connection between each parts is described.Middle part receiver assembly 800 is set Count into for Natural Circulation, and without wanting circulating pump, but one can also be arranged.Feeding water is at receptor The one half height vicinity of 800 enters and is vertically separated device 802.This relatively cool water is downward through and is in vertically The lower draft tube (not shown) of separator bottom.Water is transported to vaporizer tube panel from lower draft tube by supply pipe 850 The lower collector pipe of 822.Solar energy/heat from heliostat is inhaled by the water in the pipe flowing upwardly through vaporizer screen 822 Receiving, the density of this water is less than the density leaving the water being vertically separated device 802 so that produces and naturally pumps work With.The mixture of water vapour exits collector at the top of vaporizer tube panel 822.Upper draft tube 852 is by water The mixture of steam is transported to be vertically separated device 802, is vertically separated device 802 and separates the mixture into water and do Dry saturated vapor.The water being removed flows downward to carry out recirculation in being vertically separated device 802.

The saturated vapor being dried leaves to be vertically separated the top of device 802 and flow through saturated vapor pipeline 854 and arrives It is in the inlet header at main superheater screen 824 top.From the beginning of near vaporizer screen 822, steam flow through flat The tube side of the main superheater screen 824 of row.This arranges and is pushed by the coldest steam near vaporizer screen 822 to protect Protect superheater screen 824 to avoid overflowing on startup.When steam flows through main superheater screen, from heliostat Solar energy/heat by vapor absorption so that temperature is risen to more than saturation temperature.Then steam exits main superheater Screen 824, mixes, and flows through thermostat 856 and the pipeline 858 being associated, and then separates and enters It is in the secondary superheater screen (invisible) at top.Secondary superheater screen is positioned at middle part receiver assembly 800 On another corner.Similar with main superheater, it is parallel secondary overheated to begin to flow through near steam vaporizer screen 822 The tube side of device screen.It is overheated to protect that the coldest steam of secondary superheater is pushed near vaporizer screen by this layout Device screen avoids overflowing on startup.When steam flows through the passage of time superheater, from the solar energy of heliostat / heat by vapor absorption to promote temperature further.Final superheated steam can pass through main steam pipe (not shown) Leave middle part receiver assembly 800 (and solar receiver).

Figure 10 A is the middle part tube panel 820 utilizing side to absorb heat, and Figure 10 B is that the amplification of tube panel in the middle part of this is three-dimensional Exploded view.Reflecting module screen light barrier 836 is relatively positioned in pipe with the heat absorbing side (i.e. outside) of tube panel The rear portion (i.e. the non-exposed face of middle part tube panel) of 830.This light barrier is designed to protect insulation part 838, prop up The inner body of bearing structure 810 and solar receiver is from the most bound each tangent that may pass through tube panel The rain of the space entrance between pipe or beat exposure.The modularized design of light barrier simplifies for detecting and/or tieing up That protects removes operation.Light barrier 836 is made up of metallic plate array, and in tube side coat white paint or other Reflective material, so that the luminous energy being reflected back described pipe maximizes, and reduces the operating temperature of this light barrier. Light barrier is supported by pipe attachment structures i.e. reinforcement supporting system 814.At light barrier rear portion, (i.e. solar energy connects Receive device another inside) be the insulation part 838 covered by protective jacket.

Alternatively, in the another exemplary embodiment of solar receiver, it is contemplated that, heat transfer stream Body (HTF) is fused salt.Figure 11 shows use fused salt and flows through middle part receiver assembly 800 as fluid Schematic diagram.In this schematic diagram, fluid flow through solar receiver both sides (i.e. two tube panels 884, 886).The runner of the second parallel and independent control by the other both sides of this receptor has been not shown, but The two is identical.Starting, upper draft tube 870 provides sloppy heat salt to enter to fused salt from cold holding vessel 801 In mouth container 860, such as, " cold " fused salt can be about quilt the cold holding vessel of 550 °F from temperature Pumping.Inlet container 860 is fluidly connected to the first tube panel entrance 874 by inlet tube 872.In figure also Show the jumper pipe 896 between tube side.First tube panel outlet 876 is by cross pipe 875 fluidly It is connected to the second tube panel entrance 878.Second tube panel outlet 880 is fluidly coupled to fused salt by outlet 882 Exit vessel 862.Heat-transfer fluid can flow through the first tube panel 884 and the second tube panel 886 from inlet container 860 Arrive exit vessel 862.Lower draft tube 888 backs into downwards horizontal plane from exit vessel 862, herein, " hot " fluid can flow in thermmal storage tank 803.
