Abstract
A heat receiver tube having first, second, and further partial heat receiver tube surfaces for absorbing and transferring solar energy to heat transfer fluid is presented. The first and further partial heat receiver tube surfaces are formed by solar absorptive coatings deposited on partial surfaces of core tube. The second partial heat receiver tube surface is formed by emission radiation inhibiting coating deposited on second core tube surface for inhibiting emissivity for infrared radiation. The further partial heat receiver tube surface is arranged in radiation window of second partial heat receiver tube surface such that direct sunlight impinges further partial heat receiver tube surface. The heat receiver tube is arranged in focal line of parabolic mirror of parabolic trough collector. The first partial heat receiver tube surface and sunlight reflecting surface is arranged face to face, second and further partial heat receiver tube surfaces are averted to reflecting surface.
