This study aims to identify the factors enhancing the performance of Scheffler parabolic solar concentrators as part of the design of a solar kiln for firing ceramic materials, with a particular emphasis on the crucial role of the concentrator’s concentration factor in reaching the necessary sintering temperature of around 1000 °C. This challenge is addressed through a design methodology employing circular crossbars and rectangular mirrors, simplifying fabrication. The study further involves assessing and comparing concentration factors across multiple configurations, encompassing both traditional parabolic surfaces and rectangular mirrors. Findings indicate that using flat rectangular mirrors with dimensions of approximately (2.5 × 2.5) cm2 achieves performance levels comparable to those attained with parabolic surfaces. The Results also highlight the critical importance of accurately positioning the receiver’s surface to ensure optimal performance. Additionally, the study confirms that increasing the surface area of the dish offers significant advantages for achieving high temperatures.
Key words: Scheffler concentrator design / solar concentration ratio / Scheffler reflector performance / Scheffler concentrator area required
