Definitions

  • the invention is framed within the technology of solar collectors and more specifically it is focused on the design of solar receivers for Stirling disk.
  • the Stirling disk systems are electricity generation units that use solar radiation as a source of energy.
  • the capacity of a single unit is between 3 and 50 kWe.
  • the Stirling disk systems transform with high efficiency the concentrated solar radiation into electrical energy.
  • the essential components of the system are:
  • the mode of operation of a Stirling disk system is the following: the concentrator reflects the solar radiation to the receiver which is located at the focal point of the concentrator.
  • the solar radiation is absorbed in the receiver and this heats the gas (helium or hydrogen) of the Stirling engine at temperatures that are around 650° C. This heat is converted into mechanical energy in the Stirling engine.
  • An electric generator converts this mechanical energy into electricity. So that the reflected radiation hits the focal point during the entire day, a solar tracking system continually moves the concentrator to follow the path of the sun.
  • the technology of the solar receivers is developed depending on the type of process in which it will be used, i.e., the type of plant and the cycle used.
  • the invention filed relates to the solar receiver plant with disc and the cycle is Stirling.
  • the technologies used for solar plants in tower receivers represent a reference application.
  • the external receivers have absorption surfaces in direct view with the concentrators and depend on the direct absorption of the radiation.
  • the cavity receivers have, in turn, an opening through which the concentrated radiation passes to reach the surface of the receiver. The cavity ensures that most of the radiation that enters is absorbed by the internal surface of the receiver.
  • the receivers most widely used for the Stirling disk systems are the cavity receivers.
  • the receiver is located behind the opening to reduce the amount of lost heat and to decrease the intensity of the flow concentrated on its surface.
  • the concentrated radiation that enters through the opening of the receiver is spread inside the cavity. Most of the energy is absorbed directly by the receiver, and virtually all the remaining energy is reflected or irradiated again within the cavity to be absorbed later.
  • the first method consists of using a receiver of directly illuminated pipes, where small pipes through which the work fluid of the engine circulates are placed directly in the region where the concentrated solar flow hits.
  • the pipes form the surface of the receiver. In this way the working gas is heated as it passes through the interior of the pipes heated by the solar radiation.
  • the second method uses a liquid metal as intermediate heat transfer fluid.
  • the liquid metal is vaporized on the back surface of the receiver and is condensed in the pipes through which the working fluid of the engine circulates. That is, it absorbs the heat from the material that forms the receiver (which is hot by the exposure to solar radiation) and then transfers it to the pipes through which the working gas of the engine circulates.
  • This second type of receiver is called reflux receiver because the steam is condensed and returns to be evaporated again.
  • Invention relating to a collector for solar energy and in particular to one comprising an evaporator of a heat pipe-type heat transfer system
  • the present invention aims to provide a solar receiver that, overcoming the deficiencies found in the previous designs:
  • the new design allows to enhance the efficiency of the disc and to reduce the manufacturing and operation and maintenance costs. It also offers the possibility of:
  • the invention consists of a new receiver for Stirling disk that complies with the requirements defined previously.
  • the designed receivers comprise the following components: pipes, collectors, tanks and cupolas.
  • the receiver design claimed in this invention is composed of a series of pipes that perpendicularly exit from one collector and perpendicularly enter another.
  • the surfaces where the pipes are welded to the collectors are parallel to one another and perpendicular to the entrance of the pipes.
  • Each pipe has two 180° curves along its length so that each pipe covers almost three times the distance between the two collectors.
  • each pipe emerges from the origin collector perpendicular and in a straight line towards the target collector and before reaching the target collector turns 180° going slightly down in height and comes back in a straight line, by a horizontal plane parallel and below the departure one, towards the origin collector and before reaching the origin collector turns again 180° going down a little more in height, heading again in a straight line by a horizontal plane parallel and below the target collector, where it enters perpendicular and is connected by welding.
  • the welding point of the pipe to the origin collector is higher in height than the welding point of the pipe to the target collector.
  • each pipe consists of two semicircumferences (180° curves) and three straight parts which are: the central part, between curve and curve, and the two straight parts of the ends of the pipe, which are those that are connected to the collectors.
  • the three straight parts are parallel to each other according to horizontal planes, since all of them are at different heights, while the straight parts of the ends are in the same vertical plane, parallel to the vertical plane containing the center straight part.
  • each pipe is arranged in such a way that the straight parts of the pipe form a surface without gaps between pipes and without shading of some parts over others.
  • the arrangement at various planes of the pipes allows better cooling of the receiver by means of a fan when the temperature of the material is excessively high. Since there is greater gap between pipe and pipe, the heat transfer by convection between the air from the fan and the outer surface of the pipes will be more effective. Since there is no area of the pipes shaded by other pipes the distribution of temperatures along the pipes is more uniform.
  • the surface viewed by the concentrated solar radiation beam is completely compact, i.e., there are no gaps between the pipes if viewed from the predominant direction in which radiation hits.
  • a drawback which can be found in this design is that when the length of the pipes increases and the area of global passage decreases (sum of the passage areas of all the pipes) the associated load loss increases. This could result in a not quantified loss of engine power. But the power loss mentioned above is outweighed by the increase in the temperature of the gas. Since it has pipes of greater length, the temperature reached by the gas after it passes through the receiver is higher for the same surface temperature.
  • Another further advantage is that the manufacture of the pipes does not involve technical complications.
  • the simplest procedure would be to cut a straight pipe to the suitable length and then make the corresponding curves and angles to give it the desired final shape.
  • the best solution a priori is the placement of the sleeve since the number of cycles that it withstands is increased by a factor of five with respect to the case without sleeve.
  • the manufacturing process of the receiver it comprises the following steps.
  • the receiver model shown as well as its manufacturing process comply with the design constraints and improve the overall thermo-mechanical behaviour of the receivers known of the state of the art.
  • FIG. 1 Solar receiver from the state of the art. Patent DE19527272.

  • FIG. 2 shows the different views of the coil model solar receiver and in FIG. 3 the exploded view.
  • the receiver consists of a series of pipes ( 1 ), which are attached at both ends to two collectors and resting on the regeneration ( 4 ) and expansion ( 3 ) cupolas.
  • the receiver comprises 28 pipes ( 1 ) of a length of approximately 800 mm identical to each other and that perpendicularly exit from one collector ( 2 ) and perpendicularly entering another ( 2 ).
  • the surfaces or plates ( 5 ) where the collectors ( 2 ) are welded are parallel to one another and perpendicular to the entrance of the pipes ( 1 ).
  • FIG. 2 The plan view of the invention ( FIG. 2 below) as well as FIGS. 4 and 5 show the geometry of the pipes.
  • Each pipe ( 1 ) emerges from the origin collector ( 2 ) in a straight line ( 12 ) towards the target collector ( 2 ) and before reaching the target collector turns 180° ( 10 ) going slightly down in height and comes back in a straight line ( 11 ), by a horizontal plane parallel and below the departure one ( 12 ), towards the origin collector ( 2 ) and before reaching the origin collector it turns again according to a 180° curve ( 10 ) going down a little more in height, heading again in a straight line ( 12 ) by a horizontal plane parallel and below the target collector ( 2 ), where it enters perpendicular and is connected by welding.
  • each pipe has two 180° curves ( 10 ) along its length so that each pipe ( 1 ) covers almost three times the distance between the two collectors ( 2 ).
  • each pipe consists of three straight parts ( 12 , 11 , 12 ) and two curved parts ( 10 ).
  • the two curves ( 10 ) are semicircumferences with a radius of 11.1125 mm. and the straight parts are: the center ( 11 ) (between curve ( 10 ) and curve ( 10 )) of 220 mm and the ends ( 12 ) (between curve ( 10 ) and exit or entrance of a collector ( 2 )) of 255 mm (this includes the 3 mm of pipe ( 1 ) introduced in the collector ( 2 ) for welding).
  • the central part ( 11 ), between curve ( 10 ) and curve ( 10 ), and the two straight parts of the ends ( 12 ) of the pipe, are parallel to each other according to horizontal planes, since all of them are at different heights, while the straight parts of the ends ( 12 ) are in the same vertical plane, parallel to the vertical plane containing the center straight part ( 11 ).
  • each pipe ( 1 ) is arranged in such a way that the straight parts ( 11 , 12 ) of the pipe form a surface without gaps between pipes and without shading of some parts over others.
  • FIG. 6 shows the collector ( 2 ).
  • a row ( 20 ) are welded all the pipes ( 1 ) that have that collector as origin and in the parallel row ( 21 ) are welded all the pipes that have that collector as target. This arrangement prevents the pipes of one ( 20 ) and the other row ( 21 ) from coming into contact.
  • the distance between centres of pipes ( 1 ) of the same vertical row is equal to six times the diameter of the pipe.
  • This system is specially designed for application in Stirling disk receivers but its extension to other fields of the industry that require similar features is not excluded.
