TUBULAR RADIATION ABSORBING DEVICE FOR A SOLAR POWER PLANT WITH REDUCED HEAT LOSSES |
摘要 |
The tubular radiation absorbing device ( 1 ) for solar thermal applications includes a central tube ( 3 ) made of chromium steel, particularly stainless steel; a glass tubular jacket ( 2 ) surrounding the central tube so as to form a ring-shaped space ( 6 ); and a barrier coating ( 4 ) on at least an interior side of the central tube ( 3 ), which is substantially impermeable to hydrogen and contains chromium oxide. The barrier coating ( 4 ) is provided by a process in which the central tube ( 3 ) is treated with steam containing free hydrogen at a temperature of 500° C. to 700° C.
