Solar thermal receiver and solar thermal power generation facility

摘要

Provided is a solar heat receiver, which improves power generating efficiency in solar thermal power generation and has a reduced manufacturing cost and improved thermal shock resistance. A solar thermal power generating system using the solar heat receiver is also provided. The solar heat receiver which receives radiation of solar light and heats a fluid is provided with: a metal heat receiving section (72), which configures at least a channel wherein the fluid flows; and a heat-resistant coating layer (75), which is arranged at least on the surface of the heat receiving section (72) in a region irradiated with solar light and absorbs energy of the solar light.
