Claim:
1. A solar heat boiler, comprising: a low-temperature heating device including a heat transfer tube which is disposed horizontally so that water supplied from a water supply pump can circulate through the heat transfer tube, and a reflecting mirror which collects sunlight in the heat transfer tube, so that the low-temperature heating device can heat the water by heat of the sunlight; a steam-water separation device by which two-phase fluid of water and steam generated in the low-temperature heating device is separated into water and steam; a high-temperature heating device by which the steam separated by the steam-water separation device is superheated by heat of sunlight; and a circulating pump by which the water separated by the steam-water separation device is supplied to the low-temperature heating device, wherein: the low-temperature heating device, the steam-water separation device and the circulating pump are placed on or near a ground surface, and the high-temperature heating device is placed in a higher site than the low-temperature heating device and the steam-water separation device; and a water level gauge which measures a water level in the steam-water separation device, a water supply valve which adjusts a flow rate of water supplied to the low-temperature heating device, and a circulation flow rate control valve which adjusts the amount of water circulating between the low-temperature heating device and the steam-water separation device are provided so that the flow rate of the supplied water or the amount of the circulating water can be adjusted by the water supply valve or the circulation flow rate control valve with the water level in the steam-water separation device being set at a predetermined value which corresponds to a value to achieve annular or spray flow of the two-phase fluid of water and steam in the heat transfer tube.
