Parametric Analysis of a Concentrated Solar Receiver with Scheffler Reflector
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 5
Abstract
In this work, the effect of various parameters on the thermal performance and heat losses from the concentrated solar receiver is studied parametrically. A parabolic dish solar concentrating collector is used to heat the fluid in the receiver. The effect of the solar radiation, wind and ambient temperature on the receiver surface temperature is investigated for the thermal output. The wind velocity and ambient temperature are responsible for the heat losses from the receiver. The increase in wind velocity increases the forced convection heat losses and the increase in the ambient temperature reduces the thermal output of the system. The emissivity of the receiver coating plays a major role in the reduction of the radiation heat losses from the receiver. A reduction of emissivity from 0.9 to 0.2 decreases the radiation heat loss by 75%.
