PURPOSE: A high-efficiency solar concentrator boiler is provided to generate high-temperature steam with collecting sun-light using a mirror and tracking the sun. CONSTITUTION: A high-efficiency solar concentrator boiler comprises copper pipes(10), glass pipes(20), heat insulating materials(M3), upper and lower convex lenses and plane mirrors. The copper pipes collect solar heat and transfer the solar heat to water inside or heat medium oil(M1). A vacuum space(M2) is formed between an inner side of the glass pipes and an outer side of the copper pipes. Sun-light is incident into the copper pipes through upper and lower openings of the heat insulating material. The inner side of the insulating materials is attached to the outer side of the glass pipes with surrounding the glass pipes except the openings. The upper and lower convex lenses project the collected light to the plane mirrors. The plane mirrors reflect the light projected from the convex lenses through the upper and lower openings.
