Resumen
Selective absorber surfaces, based on soot, for solar applications were analyzed to achieve the best optical and thermal properties for a Jorhejpatarnskua solar cooker, which uses a CPC (compound parabolic concentrator) of revolution. The soot was obtained as residue of the biomass combustion in a home, from pine-wood resin sticks and resin combustion. These kinds of soot were analyzed using techniques such as X-ray energy dispersive, differential scanning calorimetry and thermogravimetric analysis. The best optical and thermal properties were presented in resin soot, which coincide with its good characteristics showing the highest C contained and the least number of mineral elements influencing in the thermal decomposition stage. A temperature that went from 200°C to 650°C was reached to begin the thermal decomposition in all kinds of soot. An additional advantage of the resin soot was its yield to produce it.
