Fabrication and Performance of Solar Parabolic Trough Concentrator With and Without Coating On Receiver Tube
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 4
Abstract
This paper is concerned with design, fabrication and experimental study to evaluate and compare the performance of two different PTCs, to produce hot water by coating and without coating black paint on receiver pipe. In PTC-1, the receiver pipe is without coating of black paint and PTC-2 receiver pipe is coated with black paint. Receiver pipe in both the PTCs are made of aluminium. Reflector materials used in both the PTCs are made of stainless steel. Rim angle and aperture area for both the concentrators are 90o and 2.131 m2. Concentration ratios for both the concentrators are 10.91. Maximum instantaneous thermal efficiency was obtained as 21.34% when solar intensity was 260 W/m2 by the concentrator which has its receiver pipe coated by the black paint.
