Abstract: A disc-type concentrator comprises a disc rack vertical post, a disc rack, a rotating shaft, a rotating reflection mirror, a power driving device, and a control system. The rotating shaft is arranged on the disc rack and rotatably connected with the disc rack. The rotating reflection mirror is arranged on a side of the rotating shaft and fixedly connected with the rotating shaft. The power driving device is arranged on the disc rack or on the back surface of the rotating reflection mirror and driving the rotating reflection mirror to rotate. The control system is connected with the power driving device and controlling the working state of the power driving device.

Abstract: An apparatus for heating a working fluid of a gas turbine-solar power generation system, comprising, sequentially connected, a cold air flow channel, a heat collecting cavity, and a hot air passage. The hot air passage is formed by connecting an inner housing on the front side to a supplemental heating section on the rear side. Also comprised is a burner for heating a primary heating air within the supplemental heating section when having insufficient solar power, and the burner is arranged at the supplemental heating section.

Abstract: The present invention discloses a dish-type solar concentration device, comprising a reflection surface, a heat absorber and a dish-type support frame being provided above and below the reflection surface, respectively; further comprising a rigid turntable and a circular orbit fixed onto the ground, the rigid turntable being connected in a rotary manner to the circular orbit through a plurality of bearing wheels, at least one support and one fixed leg being provided on the rigid turntable, a driving mechanism for adjusting an elevation angle of the dish-type support frame being provided on the top end of the support, and the top end of the driving mechanism and the top end of the fixed leg being articulated to the dish-type supporting frame by two first horizontal articulating shafts parallel to each other. By such a structure, the stability and strength of the dish-type solar concentration device can be enhanced.

Abstract: A heat collector of a dish-type solar thermal power generation system and the solar thermal power generation system having the heat collector. The heat collector of the dish-type solar thermal power generation system comprises a heat collecting cavity and at least one layer of heat absorbing coil. The heat collecting cavity is provided with an opening. The heat absorbing coil forms a cavity structure. The cavity structure is provided with a hole. The cavity structure is arranged within the heat collecting cavity. The hole and the opening are aligned. A low temperature inlet of the heat absorbing coil is arranged on the cavity structure at a location where incident light energy distribution density is at maximum. The heat collector is capable of preventing ablation of the heat absorbing coil due to localized overheating and burning of the heat collector due to abrupt drop in convective heat transfer coefficient caused by phase transition of working fluid.
