Sumario:The firing process for clay-brick production in traditional kilns generates atmospheric pollution when industrial and domestic scrap is used as fuel. Analternative is presented here, using the solar energy for clay-brick fi ring. Weare developing a system for clay-brick fi ring to reach temperatures between900°C and 1050°C, these temperatures are suffi ciently high to fi re bricks or similar ceramic products. The present paper describes the design and characterization of the components of a solar furnace for clay-brick fi ring with inner chamber dimensions of 0.48 × 0.61 × 0.64 m. To convey the sunlight to the fi - ring chamber, a heliostat with nine 1 × 1 m mirrors is used to send the rays of the sun to an off -axis parabolic concentrator that focuses the light on the entranceof the fi ring chamber. The heliostat has a solar-tracking system whichmakes primary and secondary adjustments to assure that the refl ected solar radiation always arrives at the concentrator. The fi ring chamber contains a prismatic cavity that absorbs the solar radiation to generate the heat which is needed for baking the bricks inside the fi ring chamber.
