摘要： Provided is an inexpensive and simple solar power system. A solar power system according to the present invention includes: a heat collection apparatus (2, 4) ; a steam turbine (5), a power generator (16); a superheated steam supply line which supplies the steam turbine with superheated steam generated by the heat collection apparatus; a water supply line which condenses the steam expelled from the steam turbine into water and supplies the condensed water to the heat collection apparatus; a heat storage device (8) which has a heat storage medium; a first line which branches from the superheated steam supply line and which supplies the heat storage device with the superheated steam flowing through the superheated steam supply line; a second line which branches from the water supply line and which supplies the heat storage device with the water flowing through the water supply line; and a third line which supplies the steam turbine with superheated steam generated by the heat storage device. The heat storage device stores the heat of the superheated steam which has flowed through the first line in the heat storage medium, and heats the water which has flowed through the second line with the heat storage medium to thereby generate the superheated steam.

摘要： A deviation between an inlet-outlet temperature difference of a first superheater part and an inlet-outlet temperature difference of each of second superheater parts can be reduced so that a difference in thermal expansion between the first superheater part and the second superheater part can be reduced. It is therefore possible to avoid damage on heat transfer pipes. A solar collector for a solar heat boiler is provided with: cylindrical headers (1,3,5) which are connected to opposite end portions of heat transfer pipes; and a solar heat collection portion including the heat transfer pipes and membrane bars fixing the heat transfer pipes to one another; wherein: the cylindrical headers include an inlet header (1) into which a fluid to be heated flows, an intermediate header (3) which is disposed in a position opposed to the inlet header (1) with interposition of the heat transfer pipes, and two outlet headers (5,5) which are provided to extend on opposite end sides of the inlet header and through which the fluid from the intermediate header can be discharged to the outside; and the solar heat collection portion includes a first superheating portion (2) which has a group of the heat transfer pipes connected between the inlet header (1) and the intermediate header (3) so as to form a center region of the solar heat collection portion, and second superheating portions (4,4) which have groups of the heat transfer pipes connected between the intermediate header (3) and the two outlet headers (5) so as to be formed on opposite sides of the first superheating portion (2) respectively.
