ABSTRACT
An absorber tubes of selective coatings for parabolic trough collector (PTC) having width 1.03 meter and length 1.8 meter was
developed. PTC and absorber tubes was developed by available local technology and resources. The various combinations of
absorber materials and coatings was tested for eight days with aluminum foil reflector. Combinations of absorbers are black
powder coating on copper tube, anodized coating on aluminum tube. During testing it is observed that. Increase in global
radiation causes increase in instantaneous efficiency. When PTC is covered with glass during period of 27/05/2014 to
29/05/2014 instantaneous efficiency varies from 58 % to 59 % which is more than 08 % when collector is without glass cover
having efficiency of @ 50.06%. Copper tube having black powder coating gives maximum efficiency than the anodized coating
on aluminum tube. PTC gives maximum efficiency when it is covered by glass.
Keywords: - parabolic trough collector, absorber test, absorber thermal efficiency, solar thermal application. |
