A solar collector and turbine arrangement comprising:
- a collector (1) for receiving solar radiation;
- a motor turbine (4);
- and
- a compressor (16);
- wherein:
- said collector is a radial collector (1) of conical configuration having a conduit, the interior of which being of circular or square cross section, the conduit having a path following the conical form of the collector and forming a plurality of volutes or turnings;
- the conduit being arranged so that there is no gap between adjacent volutes or turnings of the conduit, the radially innermost volute or turning of the conduit being connected with the conduit (3) feeding the motor turbine (4), the radial collector having an inlet (6) for compressed air from the compressor (16);
- the radial collector is protected by a cover which has an insulating layer (23) covering ducts (18) leading from the compressor (16) to the collector (1), wherein within the insulating layer (23) there is a layer of ceramic (13) which is solid, in powder form or in pieces and which stores heat;
- said collector (1) further comprising nozzles (30) for generating heat energy by means of gas injection which produces flame and adds heat to the air coming from the compressor (16);
- the motor turbine (4) is fed with flow heated by solar radiation in the collector (1), wherein the motor turbine (4) is connected to the collector (1) but independent from the latter, the motor turbine (4) being connected to a shaft (9) linking the compressor (16) and an alternator or generator (10);
- the arrangement comprises a heat exchanger which separates the motor turbine (4) from the compressor (16), wherein the heat exchanger has two faces connected by tubes (40) respectively having an air outlet (17) and an air inlet (24), wherein these two faces have holes and a blind wall (20) that shuts off the air from the compressor and forces it to be led to the duct (18) through the tubes (40) from the inlets (24) to the outlets (17) thereof without contacting the area of the motor turbine (4);
- the arrangement has an intermediate zone that divides the compressor (16) from the motor turbine (4), wherein holes (19) are present on the face of the heat exchanger which is in the motor turbine area at an inside diameter thereof, through said holes (19)
- gas having passed through the motor turbine (4) flows in a direction to an outlet (8) and is cut off from the compressor area by the blind wall (20) and also from the heated air passing through the tubes (40) from the inlets (24) to the outlets (17) thereof;
- the compressor (16) is configured to send the compressed air through the Inlets (24) and unpressurised air to the motor turbine (4) by means of fins (22) which form part of the central part of the compressor (16);
- and
- a central passage is arranged in the intermediate zone, wherein the central passage communicates and passes along the shaft (9) between a chamber forming a duct (31), the duct being airtight except for the compressor (16) sending ambient air by means of the fins (22) towards the blades of the motor turbine (4), central fins (21) of the motor turbine (4) sending the air outside, where it mixes with air going to the outlet (8).
